Osteoarthritis-The Role of Mesenchymal Stem Cells in Cartilage Regeneration

Osteoarthritis (OA) is a condition that can cause substantial pain, loss of joint function, and a decline in quality of life in patients. Numerous risk factors, including aging, genetics, and injury, have a role in the onset of OA, characterized by structural changes within the joints. Most therapeutic approaches focus on the symptoms and try to change or improve the structure of the joint tissues. Even so, no treatments have been able to stop or slow the progression of OA or give effective and long-lasting relief of symptoms. In the absence of disease-modifying drugs, regenerative medicine is being investigated as a possible treatment that can change the course of OA by changing the structure of damaged articular cartilage. In regenerative therapy for OA, mesenchymal stem cells (MSCs) have been the mainstay of translational investigations and clinical applications. In recent years, MSCs have been discovered to be an appropriate cell source for treating OA due to their ability to expand rapidly in culture, their nontumorigenic nature, and their ease of collection. MSCs' anti-inflammatory and immunomodulatory capabilities may provide a more favorable local environment for the regeneration of injured articular cartilage, which was thought to be one of the reasons why they were seen as more suited for OA. In addition to bone marrow, MSCs have also been isolated from adipose tissue, synovium, umbilical cord, cord blood, dental pulp, placenta, periosteum, and skeletal muscle. Adipose tissue and bone marrow are two of the most essential tissues for therapeutic MSCs. Positive preclinical and clinical trial results have shown that, despite current limitations and risks, MSC-based therapy is becoming a promising approach to regenerative medicine in treating OA.

Automated summary

Osteoarthritis is a common and painful condition for which there is currently no cure or effective symptom relief. Regenerative medicine, specifically stem cell therapy, is emerging as a promising approach to changing the course of osteoarthritis. Mesenchymal stem cells, with their unique characteristics, are considered to be a suitable source for treating this condition.
