Intervertebral discs (IVD) are among the most important structures in the human body, playing a vital role in supporting the spine and facilitating movement. With the increasing prevalence of degeneration of these discs, which poses a significant public health challenge, there is growing interest in studying their composition and functions. In this context, this article highlights the crucial role of the cartilaginous endplates (CEP) associated with intervertebral discs, reviewing the relationship between the degeneration of these plates and the pathological changes resulting from disc degeneration. We will also discuss the underlying mechanisms behind CEP degeneration, the contributing factors, as well as reviewing targeted therapies that may help slow the process of intervertebral disc degeneration. Through this article, we aim to provide new insights into the pathogenic mechanisms and regenerative repair strategies relevant to spinal health.
Health and Factors Affecting Disc Health
The intervertebral disc is a vital component of the human spine, providing support and flexibility. As age progresses and risk factors such as obesity and an inactive lifestyle increase, the disc becomes dehydrated, contributing to the deterioration of its functions. The health of the disc is affected by several factors, most notably age, where the degeneration process begins at an early age. Nutrition plays a key role in enhancing disc health, as it relies on a network of microvessels distributed throughout the cartilaginous endplates. This enhances cell vitality to effectively distribute nutrients, preventing health deterioration. Insufficient nutrition can exacerbate issues such as disc disease, where quality of life declines due to chronic pain and movement dysfunction.
The Importance of Endplates in Disc Health
The cartilaginous endplates are vital structures that reduce pressure and distribute loads across the vertebrae, helping to maintain spinal stability. The endplates function as a nutritional barrier, containing microscopic channels that allow for nutrient exchange. Reduced blood flow to the endplates can lead to deterioration in disc functions. The endplates also act as a means of protecting the disc from bulging and tearing. When the endplates degenerate, the level of nutrient and waste flow diminishes, leading to increased formation of harmful substances. These chemical compounds result in a continuous deterioration in disc health and mark the beginning of disc degeneration. Therefore, maintaining proper nutrition and care for the cartilaginous endplates is essential to preserve the health of this vital area.
The Relationship Between Endplate Degeneration and Spinal Disorders
The condition of the cartilaginous endplates affects the development of spinal problems, such as disc herniation and arthritis. Research indicates a clear correlation between endplate degeneration and changes known as Modic changes, which are early indicators of disc degeneration. These changes appear through magnetic resonance imaging, indicating inflammation and issues with blood supply. Studies suggest that degeneration of the endplates significantly contributes to the development of these health issues. Inefficient blood flow may exacerbate lipid deposits, increasing pressure on the spine and consequently leading to chronic pain.
New Therapeutic Strategies to Improve Endplate and Disc Health
Recent years have seen remarkable developments in research related to treating endplate degeneration and disc disease. One emerging trend is the use of stem cell therapy, which shows promise in repairing damaged tissues. These treatments aim to enhance blood flow and improve disc nutrition. The integration of “targeted” molecular therapy to boost collagen production and improve nutritional diversity is being explored. The use of certain growth factors to stimulate the proliferation of cartilaginous cells and assist in tissue regeneration is also under investigation. Furthermore, ongoing research highlights the importance of identifying genetic causes of endplate degeneration, which may assist in developing tailored therapies according to the patient’s genetic characteristics. These comprehensive innovations require further studies to confirm their effectiveness and expand their use in improving spinal health overall.
Osteoporosis
Genetics and Its Role in Intervertebral Disc Degeneration
Genetic fragility is a key factor contributing to intervertebral disc degeneration (IDD), as research shows that certain components of the extracellular matrix (ECM), such as COL2, COL9, and COL11, play a vital role in this context. The gene COL2A1, for example, is associated with the occurrence of IDD, and studies have shown that gene silencing of this gene in mice reveals significant negative effects on disc structure. Mice with partial gene silencing exhibited a thicker and more irregular cartilaginous end plate (CEP), indicating early damage. This underscores the importance of COL2 in maintaining the natural characteristics of the disc layer.
On the other hand, the gene COL9A2 also plays a pivotal role, as studies indicate that the loss of this gene leads to abnormal remodeling in the supportive tissues of the discs, making them more susceptible to degeneration. Understanding these intricate genetic relationships can aid in developing new therapeutic strategies that address the causes of IDD starting from the molecular level.
Immune Response and Inflammation
Intervertebral discs are the largest avascular structures in the human body, making them particularly susceptible to inflammatory conditions. When the CEP undergoes degeneration, it leads to increased production of cytokines such as IL-1 and TNFα, which promote catabolic processes in the disc. This sets the stage for microbial invasion that may stimulate the proliferation of immune cells in the affected area, exacerbating symptoms and increasing IDD severity.
When degeneration occurs in the CEP, the disc becomes prone to inflammation and can develop a favorable environment for bacterial growth. Studies suggest that cells within the discs may exhibit characteristics similar to immune cell functions, effectively performing phagocytosis and clearing dead cells. Severe mechanical stresses also play a significant role in increasing the risks associated with degeneration.
Progression of Degeneration after Injuries
Injuries resulting from sustained high pressure can lead to degeneration of intervertebral discs. For instance, excessive loading can damage the central part of the discs, allowing proteins within the disc to bulge through the CEP into the vertebral bones. This results in the formation of what is known as Schmorl’s nodes. Research indicates that these nodes are a significant pathological change associated with disc degeneration and can lead to major complications.
Multiple hypotheses explain how these nodules occur, with some studies suggesting that various vascular changes during growth may be the primary cause. Other studies propose that minor breakdown in the surrounding tissues may lead to herniation of the gelatinous material, causing nodules to form. Addressing the effects of these injuries is a crucial focus for understanding future treatments for IDD patients.
The Impact of Smoking on Disc Degeneration
Smoking is one of the major contributing factors to CEP degeneration and accelerates the process of IDD. Studies have shown that smoking reduces the content of glycosaminoglycans (GAG), a vital component necessary for maintaining the functionality of structural discs. The chemicals present in tobacco also affect blood flow, reducing the discs’ ability to exchange nutrients. Research further indicates that exposure to secondhand smoke impacts the gene expression of important factors related to disc health.
Increases in gene expression of nucleotidases have shown that smoking negatively affects bone structure. This demonstrates the close relationship between spinal health and lifestyle factors. Quitting smoking is recommended as a preventive measure against cognitive decline and mechanical injuries.
The Relationship
Degeneration of CEP and Modic Lesions
The degeneration of CEP and Modic lesions is an important topic in studying the relationships between pathological changes in discs and the adjacent vertebral tissues. MRI studies show that injuries in CEP often lead to changes in the signal of the adjacent bones, known as Modic changes. These changes are classified into three types that illustrate the health status of the surrounding bone tissues, allowing physicians to diagnose degeneration from various angles.
Research has linked CEP degeneration to an increase in dysfunction in the structural properties of bones, as materials associated with proteins found in the vertebral layer are linked to changes and are made more vulnerable. Immune and inflammatory factors significantly intersect in this relationship, making it essential to guide future research towards understanding how targeted therapies can contribute to enhancing healing.
Modic Changes and Their Impact on Immune Cells in the Intervertebral Disc
Modic changes are important phenomena that affect the spine, often seen in patients suffering from various spinal issues. Following the occurrence of Modic changes, cells in the tissue area surrounding the intervertebral disc, known as the transitional zone (CEP), interact with the immune system in a way that may lead to damage to these tissues. Studies have shown that cells in the CEP region express higher amounts of Tumor Necrosis Factor (TNF) and Macrophage Migration Inhibitory Factor (MIF), along with its specific receptor CD74. These factors play a central role in triggering a strong inflammatory response, where TNF increases the production of MIF, contributing to the enhanced secretion of additional inflammatory factors, indicating the presence of a feedback loop that may worsen the health condition of the intervertebral disc following Modic changes.
One negative impact of this relationship is that damage occurring in the CEP can lead to ongoing inflammation with the vertebral body, contributing to the worsening of pathological symptoms like back pain. Additionally, Modic changes allow components from the nucleus pulposus (NP) to have direct contact with the immune system, leading to an immune response that may negatively affect the adjacent tissues, including the CEP. Therefore, it is important to understand how these changes impact the overall condition of the spine and how they may interfere with future therapeutic processes.
Modern Therapies Targeting CEP and Delaying Disc Degeneration
Medical care options for spinal pain resulting from degenerative disc disease include both surgical and non-surgical treatments. While these therapies aim to alleviate symptoms, many do not restore the biomechanical function of the disc as required. Recently, regenerative medicine and tissue engineering have emerged as promising solutions to treat spinal issues, as these treatments focus on targeting specific tissues according to the stage of degeneration. In the early stages, cellular activities within the tissues remain active, and these activities can be exploited to stimulate cell regeneration through molecular therapies. As the condition progresses, therapeutic interventions may require additional modalities, including cell transplantation and platelet-rich plasma therapies.
During the later stages of degeneration, cellular changes are quite evident, and treatment relies on using cellular structures and biomaterials to support the compensation of damaged tissues. Reviewing these treatments is essential for understanding how to address disc degeneration and tackle its root causes. Furthermore, a deep understanding of these mechanisms can provide new insights into treating spinal disorders.
Molecular Stimulation and Cell Therapy in Delaying Degeneration
Molecular therapy is considered a promising option in the early stages of disc degeneration. This treatment involves injecting growth factors or other molecules into the disc to stimulate cell growth and increase metabolism of materials in the affected area. A study indicates that injecting compounds capable of binding calcium in the CEP area led to significant improvement in nutrient supply to the disc, reflecting the effectiveness of this type of treatment. However, the potential risks of molecular therapy must also be considered, as these treatments may accelerate the occurrence of additional injuries in the CEP, leading to exacerbation of the degeneration condition.
Increase
Molecular therapy includes the use of a product called MMP8, which helps improve nutrient absorption within the CEP, aiding in delaying extinction. Despite these benefits, the possibility of tissue irritation or chronic inflammation due to repeated injections should be considered. It is important to have a thorough assessment of the potential risks associated with molecular stimulation to minimize possible negative effects.
Cell Cultivation** and its Associated Challenges in Treatment Procedures
Cell cultivation represents an effective means of addressing degenerative disc extinction, as many clinical trials have been conducted using autologous cells and cells derived from donors. The main advantage of using autologous cells is that there is no risk of microbial transmission, and these cells possess a modified ability to survive in tissues. However, cell cultivation faces several challenges, including the necessity for the transplanted cells to survive in a harmful environment, and when they succeed in surviving, they need to have adequate nutrients to support their growth and metabolism.
Another challenge is ensuring good connectivity between the transplanted cells and the patient’s tissues, as insufficient integration may lead to repeated extinction. Additionally, using donor-derived cells may involve immune risks, necessitating the use of immunosuppressive drugs which may carry their own risks. Therefore, it is crucial to conduct a comprehensive evaluation of the long-term implications of cell transplantation and its impact on treatment efficacy.
Tissue Engineering and Regenerative Medicine as Effective Treatments for Degenerative Extinction
Tissue engineering and regenerative medicine represent new innovations in the field of treating degenerative extinction. Regenerative medicine focuses on reconstructing damaged tissues by utilizing multifunctional biomaterials that support cell growth and enhance the properties of targeted tissues. However, issues arise from the inability to effectively integrate these materials with living tissues, which can lead to chronic inflammation in the absence of optimal integration between the materials and the surrounding biological structures.
There is also a concern regarding the mechanical effects of these materials in the natural environment of the spine, where failure to withstand mechanical forces raises concerns about the durability and effectiveness of these materials over time. Current studies highlight the importance of interaction between the implanted materials and supporting cells. Consequently, the focus should be on developing materials that can be properly integrated with living tissues, marking a pivotal shift in emphasis on the necessary research and techniques in this field.
Disc-like Endplate Structures as Ideal Alternatives
Disc-like endplate structures (eDAPS) are promising models for intervertebral disc replacement in animal studies. These structures are made from porous polycaprolactone (PCL) foam, integrated with components from the nucleus pulposus (NP) and annulus fibrosus (AF). Research has shown that after 20 weeks of implantation, live cells from adjacent tissues migrate into the CEP structure, gradually leading to the production of matrix components and rare blood vessels. This process is crucial for reversing degeneration in the CEP and enhancing nutrient diffusion in the intervertebral disc. This suggests that developing effective regenerative materials for both NP and AF, while promoting stable integration with CEP, could lead to a more efficient reconstruction of the intervertebral disc. However, it should be noted that vascularization significantly impacts slowing the degeneration of the intervertebral disc when targeting CEP, but if it occurs in NP tissue, it may accelerate degeneration and worsen clinical symptoms such as lower back pain.
Research
Applications in 3D Bioprinting
3D bioprinting is a popular technique in tissue engineering research, but it faces numerous challenges. In recent years, researchers have used various types of bioprinting inks, such as aluminum sheets or carbon fibers, to enhance structural strength and recreate load-bearing tissues like the CEP. However, printing accuracy has been a significant challenge in this field. Furthermore, using a decellularized extracellular matrix is another option that not only addresses issues like low printing accuracy but also contributes to the design of 3D printed structures. Nevertheless, the mechanical properties of modified chemical matrices are weak compared to the original tissue, and factors such as expandability, low reproducibility, and high manufacturing costs hinder the development of new intervertebral disc constructs.
Research on Traditional Chinese Medicine and Its Effects on CEP Degeneration
For millennia, traditional Chinese medicine has been employed in Asian countries such as China, Japan, and South Korea to treat various musculoskeletal disorders, including intervertebral disc degeneration. Curcumin, the active ingredient in turmeric, has anti-inflammatory and antioxidant properties and stimulates cell division. Researchers created a model of CEP cell degeneration by inducing cyclic tensile loading and applying curcumin to observe changes in function and metabolism in CEP cells under high tensile stress. Results showed that curcumin could inhibit cell death through the autophagy pathway, reduce morphological loss related to CEP cells caused by high stress, and alleviate intervertebral disc degeneration due to mechanical imbalance. Additionally, sulforaphane A exhibits the ability to enhance vascular tissue permeability, targeting specific factors to mitigate extracellular matrix degradation in CEP cells.
Modern Treatment Strategies Targeting CEP
In this area of modern medical care, there is a consensus that CEP degeneration and its microvascular network accelerate intervertebral disc degeneration. Studies indicate that the process of intervertebral disc degeneration driven by CEP is a slow and complex process closely related to factors such as natural degeneration, genetics, immunity, injury, and smoking. Modern approaches, such as molecular therapy, offer opportunities to influence the early stages of disc degeneration by enhancing nutrient supply and preventing damage to surrounding tissues. On the other hand, stem cell research shows potential for achieving better regeneration, but more clinical studies are needed to ensure its effectiveness.
Future Challenges in Intervertebral Disc Research
Despite the progress made in strategies addressing CEP degeneration, many research gaps still exist. Current studies predominantly focus on pathological, physiological, and biomechanical aspects, with limited exploration of the genetic and immune factors involved. Most studies on Western and Chinese medicine treatments concentrate on laboratory experiments, highlighting the need for studies involving animal or human models. Ongoing research is crucial to expand our understanding of these diseases and explore the complex interactions between genetic and environmental factors and their impact on CEP degeneration.
Causes of Intervertebral Disc Degeneration
Intervertebral disc degeneration is a common health issue that impacts people’s mobility and quality of life. Disc degeneration refers to the wear and tear of the cartilage covering the discs, leading to loss of disc elasticity and increased pressure on adjacent vertebrae. Genetic and environmental factors are among the main causes of this degeneration. For example, research shows that repeated exposure to certain movements or physical stress can exacerbate the condition. Aging is also a significant factor, as cartilage naturally deteriorates over time due to loss of water and nutrients.
Added
external factors such as smoking and obesity, where smoking is associated with reduced blood flow to the cartilage tissues, accelerating the degeneration process. Additionally, excess weight adds extra pressure on the spine, increasing the risk of disc problems. Furthermore, a sedentary lifestyle can also lead to weakness in the muscles surrounding the spine, increasing the risk of injury.
Psychological factors are also part of the picture, as studies have shown that individuals experiencing psychological and emotional stress may face an increase in symptoms related to disc degeneration. The psychological factor contributes to pain management and coping with stress, which may affect physical health.
Evaluation Methods for Spinal Disc Degeneration
Imaging assessments such as MRI and X-rays are vital tools in diagnosing spinal disc degeneration. These tools help determine the severity of degeneration and reveal changes in surrounding tissues, such as vertebral inflammation or spinal canal narrowing. MRI provides a precise view of soft tissues, such as intervertebral discs, and can detect herniated discs, a condition that occurs when a disc protrudes from its normal position.
Additionally, clinical assessments involving movement tests and functional assessments are used to evaluate the impact of degeneration on individuals’ quality of life. These tests assess pain and mobility, assisting doctors in developing an appropriate treatment plan. Genetic testing is also playing an increasingly important role in understanding individual risks for spinal degeneration, as research has shown that certain individuals may be more susceptible to disc degeneration due to genetic factors.
Treatment strategies are based on the severity of symptoms, age, and overall health factors. These strategies may range from physical exercises and physical therapy to surgical procedures in severe cases. The goal is to manage pain and improve movement and quality of life.
Treatment and Intervention Strategies
Effective treatment strategies for spinal disc degeneration involve a combination of non-surgical and surgical treatments. Non-surgical techniques, such as physical therapy and targeted exercises, help strengthen and improve flexibility. Flexibility exercises and stretching techniques are an essential part of treatment, as they help improve range of motion and reduce pain.
Medications are also used as part of the treatment plan. Non-steroidal anti-inflammatory drugs can aid in pain management and reduce inflammation. In cases where conventional treatments do not improve symptoms, advanced therapies such as injections, like corticosteroid injections or platelet-rich plasma, may be considered to target the affected area directly.
In severe cases of degeneration, surgery may be required. Surgical options may include discectomy or disc replacement. These procedures are handled with care, and the benefits and risks must be assessed before making a decision. The goal of surgical intervention is to reduce or eliminate pain and restore spinal function.
Recent research aims to develop new techniques to treat disc degeneration, through the use of stem cells to promote healing in damaged discs. This technology may provide new hopes for patients whose conditions do not respond to conventional treatment.
Disc Degeneration and Its Health Effects
Disc degeneration is a common condition affecting individuals worldwide. It is considered a major cause of chronic back pain, negatively impacting quality of life. This degeneration results in a loss of disc flexibility and its ability to withstand stress, increasing the risk of herniated discs and nerve pain. Some studies indicate that genetic factors play a role in disc degeneration, with specific genes associated with an increased risk of this condition, highlighting the importance of genetic factors in spinal health.
known factors that contribute to spinal disc degeneration are aging, where the body’s ability to regenerate tissues and utilize nutrients declines. Additionally, lifestyle factors – such as physical inactivity and smoking – play a significant role in exacerbating the condition. For instance, smokers have been found to be more susceptible to developing disc problems compared to non-smokers, as smoking negatively affects blood flow to the discs and increases inflammation.
These factors lead to the degradation of the disc structure, which enhances the sensation of pain and decreases daily performance. In many cases, this requires multiple therapeutic interventions, ranging from physical therapy to surgical options, aimed at alleviating pain and restoring flexibility.
Biotechnology Treatment Strategies for Disc Regeneration
Biotechnology treatment strategies are considered effective tools in formulating new therapies against spinal disc degeneration. Among these strategies, biomaterials such as hydrogels made from alginates are used, which have been shown to enhance tissue healing and regenerate damaged tissues. This type of treatment provides an ideal platform for the application of stem cells and units for studying cellular interactions in a suitable environment. Researchers have monitored the effect of hydrogels on stem cell responses, allowing the spinal disc to recover and regain its lost elements.
Furthermore, studies show that the use of stem cells in treatment provides an important opportunity to stimulate disc regeneration through cell renewal and reduction of inflammation. Stem cells derived from various tissues, such as spinal cord tissue and bone tissue, have been studied to identify the best methods for spinal disc regeneration.
Clinical applications based on this research are promising, especially in the potential to significantly reduce pain and improve functional capacity for patients suffering from severe disc degeneration. However, there is still a need for further research to understand the detailed biological mechanisms and how to enhance tissue regeneration.
Future Challenges in Treating Disc Degeneration
Despite significant progress in biotechnology and healthcare, there are multiple challenges that still require special attention. The challenges point to technical limitations regarding the effectiveness of available treatment strategies. For example, the individual response to treatment needs to be evaluated, as patient responses can vary widely due to genetic and environmental factors.
Long-term safety and the impact on quality of life are major issues that require further study, in addition to legal and regulatory obstacles that may hinder the application of new treatments. There should be a clear framework to ensure that these new strategies are safe and effective before they are implemented on a large scale.
There is also an urgent need for long-term clinical studies to gain a comprehensive understanding of the effects of new treatments on disc degeneration and their impacts on overall quality of life. Therefore, collaboration between researchers and medical clinics is essential to enhance understanding, develop future therapies, and provide suitable and safe options for patients.
Addressing Lower Back Pain and Contributing Factors
Lower back pain (LBP) is one of the main factors affecting human quality of life. This condition is considered a public health problem, as issues related to it are increasing in parallel with an aging population. Lower back pain poses a significant economic burden, affecting productivity and increasing healthcare costs. Lower back pain is associated with various pathological changes such as intervertebral disc degeneration, which occurs due to multiple factors including genetics, obesity, aging, and an unhealthy lifestyle. Essentially, this degeneration is characterized by a loss of water content in the disc tissues, leading to decreased flexibility, reduced height, and an inability to adequately respond to mechanical loads.
Causes
Pathological changes associated with spinal disc changes, such as bone formation outside the vertebrae, vertebral instability, and disc herniation, contribute to increased lower back pain severity. The spinal disc is one of the largest avascular structures in the human body, making nutrient supply critical for its functions. The small vascular plexus within the cartilaginous endplate (CEP) plays an important role as it facilitates the exchange of nutrients and waste within the spinal discs.
Structure and Activity of the Cartilaginous Endplate and Small Vascular Network
The [[IVD]] consists of an avascular structure made of fibrous tissues that separates the vertebrae, allowing them to withstand loads and provide effective flexibility during movement. The cartilaginous endplate (CEP) extends due to layers of thick spongy bone and hyaline cartilage, forming the upper and lower boundaries of the spinal disc. The cartilaginous endplate plays a vital role in preventing disc protrusion into adjacent vertebrae and provides important mechanical support for the stabilization of the nucleus pulposus (NP) and annulus fibrosus (AF).
The cartilaginous endplate is part of the main nutritional network for the spinal disc. At the junction where the cartilaginous endplate meets the apex of the bones, a dense network of blood vessels is formed, extending into the spinal canal, known as the “vascular network ring.” These vessels are mainly distributed in the central region, which contains numerous hematopoietic stem cells, fats, and nerves. These vascular structures enhance the delivery of nutrients and waste to the spinal disc.
Deterioration of the Cartilaginous Endplate and Its Effects on Spinal Health
Deterioration of the cartilaginous endplate involves the reduction of blood vessels and decreased permeability, leading to an imbalance in the energy metabolism process within the spinal disc, which is a primary cause of disc degeneration. Inadequate nutrient intake is a key factor in triggering this deterioration. Microstructural changes in the vascular bundles within the cartilaginous endplate lead to the formation of pathological changes in the spinal disc, thus exacerbating the patient’s health condition.
Studies indicate that inadequate nutrient supply can evolve into a pathological condition that leads to increased severity and dysfunction of the disc. This drives patients to suffer from more pain, and spinal health complications, such as the emergence of new bone in the vertebrae or nerve injuries. Periodical sources attribute these changes to a deficiency of normal nutrient levels in the spinal discs, which are essential for disc function.
Treatment Strategies and Therapeutic Developments for the Musculoskeletal System
Current treatment strategies aimed at addressing the deterioration of the cartilaginous endplate and its effects on the spinal disc are diverse. Surgical treatment techniques play a crucial role in alleviating pain and improving the quality of life for patients. However, there is a notable increase in research on advanced treatments such as stem cell therapy, which appears promising in restoring disc tissue.
These treatments represent a significant advancement in the field of precision medicine, aiming to leverage the vascular endplate (CEP) as an essential component of therapy. Research has been conducted on the effects of these treatments that show efficacy in slowing the disc degeneration process, while also supporting the regeneration of cellular systems.
Future research recommends additional clinical studies to ensure the efficacy of these treatment strategies based on clinical and laboratory investigations. There is an urgent need for innovation in comprehensive treatment methods that take into account multiple aspects covering nutrition, rehabilitation, and surgical interventions to improve outcomes for patients suffering from spinal disc degeneration.
The Importance of Ongoing Research in Spine Medicine
Efforts to improve spinal health or address disc degeneration require meticulous examination and ongoing research to understand the complex biological processes governing them. The key lies in exploring new ways to understand the impact of nutrition on the spinal disc and restore the vital capabilities of the vascular system.
Represent
Future research is a vital step toward improving treatments and intervention techniques, thereby enhancing the effectiveness of current therapies. Strengthening education and clinical practice is a critical investment for the future as the healthcare system faces ongoing challenges due to imbalances caused by spinal degeneration and its diseases.
Common Causes of Endplate Degeneration in Intervertebral Disc Degeneration
Endplates (CEP) are a vital part of the intervertebral disc, playing a crucial role in maintaining the spine’s health and nutrition. Many individuals suffer from the degeneration of these endplates, contributing to the development of conditions like intervertebral disc degeneration (IDD). The causes of CEP degeneration are varied, and one of these causes is the natural deterioration associated with aging. This process begins at an early age as bone growth affects the internal environment of the endplates, increasing the rate of cell death and leading to the formation of calcified foci. As one ages, blood flow through the microvessels decreases, affecting the disc’s ability to obtain essential nutrients. For instance, the degeneration of endplates contributes to a reduction in collagen concentration, thereby negatively affecting disc health.
Genetic factors also play a significant role in the development of endplate degeneration. Studies suggest that genetic changes may contribute up to 74% to intervertebral disc degeneration. The analysis of twins is an example of how heredity impacts the manifestation of disc degeneration cases.
On another front, the immune inflammatory response can also be a significant factor; as the intervertebral discs are a source of numerous cytokines that promote catabolic processes within the discs, making them an ideal environment for bacterial growth. These cytokines increase during endplate degeneration and exacerbate the condition.
On the other hand, exposure to injuries resulting from excessive pressure on the spine, such as undue stress on the back area, can lead to damage to the endplates and increase the risk of intervertebral disc degeneration.
Degeneration Resulting from Environmental and Lifestyle Factors
Environmental factors and lifestyle, such as smoking, play a primary role in endplate degeneration. Smoking is a detrimental factor affecting the health of connective tissues, as it reduces the content of essential nutrients such as glycosaminoglycans in the endplates. Smokers experience faster deterioration in intervertebral disc health due to nicotine’s effect, which reduces blood flow through the microvessels of the endplates.
In addition, passive smoking is also a compelling causative factor that requires monitoring. Studies indicate that the adverse effects of passive smoking are not far removed, as it impacts the gene expression of tissues associated with the spine. All these factors lead to rapid degeneration of spinal discs and increase the risk of developing back problems such as back pain.
Exposure to an unhealthy environment and harmful environmental factors, along with unhealthy lifestyle patterns, such as lack of exercise and prolonged sitting, are important factors that negatively impact the health of the endplates. Studies have proven that regular exercise promotes spinal health and reduces the risk of intervertebral disc degeneration.
Theories Related to the Formation of Schmorl’s Nodes and Their Impact on the Spine
Studies indicate that the formation of Schmorl’s nodes is intrinsically related to damage to the endplates. These nodes are a marker of the permanent injury sustained by the spine due to continuous stress or injuries, leading to the herniation of the intervertebral disc into the vertebral bones.
The traditional theory regarding Schmorl’s node formation is linked to abnormal changes in spinal vascularization during developmental stages. Some perspectives suggest that internal blood vessels suffer early collapse, causing the intervertebral discs, even into adulthood, to be inadequately vascularized, thereby weakening the function of the endplates.
While this theory is supported, there are varied opinions on the physiological mechanisms that determine the formation of Schmorl’s nodes. Studies of tissue analysis have shown that complex manipulations occur beneath the endplates, indicating the presence of necrosis resulting from chronic blood deficiency. On the other hand, the formation of these nodes is associated with catabolic tissue processes, suggesting a complex interaction between the organism and environmental factors.
Response
The Immune System and Its Role in Tissue Degeneration
The immune response is considered one of the critical factors that play a role in tissue degeneration, as the role of endplates emerges as a barrier between the intervertebral disc and the immune system. When the endplates deteriorate, the immune interaction begins to affect the cellular level within the intervertebral disc. Responsive cytokines induce a stimulatory environment that accelerates tissue degradation and increases inflammatory processes.
The intervertebral disc is characterized by the presence of distinctive microbic cells within the tissues, which play a significant role in stimulating immune responses. If the endplates are intact, the intervertebral disc is considered a tissue protected from immune readiness. However, when the endplates deteriorate, these cells begin to increasingly interact with what is known as the microbial cell, enhancing inflammation and metabolic slips.
In general, the immune response in the tissues is regulated by a complex set of elements, including the balance of cytokines and metabolic factors. The degeneration of the endplates is associated with increased rates of immune reactions, leading to further functional degeneration.
Future Directions in Treating Intervertebral Disc Injuries and Degeneration
Back pain and intervertebral disc degeneration represent a significant health challenge in the contemporary world. Therefore, it is important to develop new treatments and management methodologies to assist patients. In addition to traditional medicine, researchers are turning toward methods that combine modern medical technology with spinal rehabilitation.
Recent trends include gene therapy, where gene-targeting techniques are used to improve tissue composition and restore healthy functions. The importance of research on stem cells and their ability to regenerate damaged tissues also stands out, presenting great hope in treating injuries and critical conditions.
Additionally, the focus on lifestyle and mental health is a key factor in determining success and treatment. Emphasizing the importance of maintaining physical activity and avoiding negative factors such as smoking or obesity is fundamental to addressing spinal issues. By combining traditional and modern therapeutic techniques, significant progress will be achieved in the treatment and rehabilitation associated with intervertebral disc problems.
The Effect of Smoking on Circadian Clock Genes
Studies have shown that smoking, whether active or passive, significantly impacts the expression of many genes associated with the circadian clock. In particular, it has been observed that these genes exhibit circadian rhythmic expression in intervertebral disc (IVD) cells, where most of them show a phase shift ranging from 6 to 9 hours when exposed to passive smoking. This effect alters cellular functions in the intervertebral disc, leading to delays in the biological response to certain growth factors, and consequently may influence the tissue regeneration process.
Furthermore, evidence suggests that smoking also changes the expression of protease enzymes and protease inhibitors. These changes lead to a reduction in the expression of nucleus pulposus (NP) marker genes, increasing the risk of cell depletion in the intervertebral discs. Epidemiological studies suggest that when risk factors such as systemic diseases, harsh working conditions, obesity, injuries, and family history are excluded, smoking significantly contributes to the degeneration of lumbar discs, indicating a strong relationship between smoking and the exacerbation of degeneration in intervertebral discs.
Focusing on the importance of quitting smoking, it becomes clear that it may help prevent the degeneration of the cartilage endplate (CEP) and thus may contribute to slowing down the process of intervertebral disc degeneration. For example, data indicates that quitting smoking may generally improve the immune response of the body and enhance the ability of tissues to regenerate, providing a better environment for cell and membrane representation.
Conclusions
Clinical Changes Associated with Modic Changes
The changes in MRI signal intensity of the vertebrae surrounding the intervertebral disc, known as Modic changes, are significant topics in the study of degenerative diseases. Modic changes are classified into three types based on MRI technology. Type I exhibits low signal intensity on T1 images with high signal intensity on T2 images, historically representing reduced fluid balance due to inflammation in the tissue. Type II is characterized by high signal intensity on T1 images and moderately or equally high signal on T2 images, indicating the presence of microfractures or fissures. Type III, on the other hand, shows low signal intensity on both T1 and T2 images, suggesting stiffness changes in the CEP tissues.
Many studies indicate that injury to the outer covering of the disc associated with Modic changes plays a pivotal role in exacerbating degenerative diseases such as intervertebral disc degeneration. Thus, it becomes crucial to investigate the relationship between CEP injury and Modic changes from a clinical perspective. This research aids in identifying effective methods to mitigate horizontal tissue degeneration related to pain reduction and improving patients’ quality of life.
Furthermore, the relationship between CEP injury and Modic changes may contribute to a deeper understanding of the widespread inflammatory mechanisms that facilitate the disease’s progression, potentially leading to new treatment strategies. For example, future studies may indicate the importance of targeting inflammation resulting from these changes as part of treatment protocols.
Modern Medicine Strategies Targeting Intervertebral Disc Covering Improvement
Research related to treating degenerative spinal diseases is among modern research areas aimed at providing new strategies to enhance clinical outcomes. In addition to traditional treatment methods, both surgical and non-surgical, regenerative medicine and tissue engineering methods emerge as promising new options for improving the overall health of the intervertebral disc. In the early stages of disc diseases, cellular activity within the disc tissue is high, allowing this tissue to respond effectively to treatments.
Molecular therapies, such as growth factor injections, can be effective in enhancing tissue balance within the intervertebral disc, contributing to delaying disease progression. Additionally, studies have shown that improving nutrient availability within the intervertebral disc can lead to enhanced genetic information of the tissues and cell regeneration. For instance, the injection of certain compounds has improved blood flow and circulation in that area.
As this treatment progresses, transplanted cells face various challenges, including oxygen deficiency and excessive immune response conditions. Thus, cell transplantation processes are vital solutions that need to be considered. However, cell transplantation faces many challenges, including the need to enhance the successful integration of transplanted cells with intervertebral disc tissues.
Incomplete Integration with Host Tissues
The issue of incomplete integration with host tissues stands as a major challenge in cell therapy, leading to recurrent dissolution. This type of dissolution can have dire consequences on the efficacy of treatment and the ability of new tissues to integrate properly with the surrounding tissues. In many cases, these issues lead to re-exposure of the transplanted cells to dissolution again, emphasizing the need for evaluating the long-term effects of cell transplantation. Among the significant concerns that must be addressed are immune rejection, especially when using foreign cells, where patients may face immune risks requiring immunosuppressive treatments. These beneficial therapies may also carry negative side effects that impact patient health. Therefore, it is crucial to conduct long-term studies to understand these consequences and the potential for cellular mutations or cancerous transformations over time, as these factors could significantly affect the overall safety and efficacy of cell therapies.
Techniques
Tissue Engineering and Regenerative Medicine
Tissue engineering and regenerative medicine are advanced fields that provide new possibilities for delaying intervertebral disc degeneration (IDD). The core idea behind tissue engineering is to reconstruct and regenerate damaged tissues, and composite biological materials are considered key tools in this process. Biological scaffolds provide a three-dimensional space that ensures functional and structural stability for the cells involved in the regenerative repair process. However, the long-term integration of these engineered tissues with the host tissues remains a major challenge. The less the scaffold is integrated, the more it may cause chronic inflammatory responses, leading to further degradation of the treated tissues. Despite the success of some studies, the materials used still require improvement in mechanical properties to withstand physiological loads and meet the requirements for normal function.

However, caution should be exercised as repeated therapies may lead to damage to other tissues or negatively affect the energy balance in the patient’s body.
Modern Treatment Strategies and Future Research
Current treatment strategies require a separation of the different stages of disc degeneration. Stages of degeneration range from early stages where the focus is on improving nourishment, to intermediate stages where the use of autologous cell grafts is preferred to reduce the risk of immune rejection. Cell transplantation is a common option, but it faces challenges related to the rapid loss of grafts in the harsh disc environment. Research on stem cells derived from endplates and several modern techniques shows promise in improving repair techniques.
Tissue engineering and regenerative medicine are promising therapies targeting the late stages of degeneration. These strategies rely on reconstructing damaged discs using biological materials and scaffolds, while the main challenge remains achieving strength and stability similar to the original tissue. Challenges lie in cell integration with the new tissue and minimizing inflammation caused by the implantation of foreign materials. New research is moving towards using three-dimensional printing technologies and engineered tissues, along with increasing vascularization to achieve effective repair.
