Osteoarthritis (OA) is a common disabling joint disorder. This review explores how mesenchymal stem cells (MSCs) and regenerative therapies like PRP and exosomes may reverse early OA progression.
Area of Science:
- Orthopedics and Regenerative Medicine
- Musculoskeletal Disorders
- Immunology
Background:
- Osteoarthritis (OA) is the most prevalent chronic musculoskeletal condition, a leading cause of disability in older adults.
- OA involves a progressive degenerative cycle affecting the entire joint, including inflammation, cartilage breakdown, and bone erosion.
- Early OA is characterized by inflammatory-immunologic processes and the involvement of specific cells like synoviocytes and chondrocytes.
Purpose of the Study:
- To investigate the role of joint-resident mesenchymal stem cells (MSCs) in maintaining joint homeostasis and tissue repair.
- To explore the potential of minimally invasive interventions for halting and reversing early-stage OA.
- To review regenerative therapies including platelet-rich plasma (PRP), MSCs, and exosomes for OA treatment.
Main Methods:
- Literature review focusing on the pathophysiology of osteoarthritis.
- Analysis of the role of resident mesenchymal stem cells (MSCs) in joint regeneration.
- Examination of current and emerging regenerative interventions for early OA.
Main Results:
- Mesenchymal stem cells (MSCs) play a crucial homeostatic role, regulating cell turnover and tissue repair within the joint.
- MSCs establish and maintain a local regenerative microenvironment essential for joint health.
- Understanding OA pathogenesis highlights mechanisms for regenerative interventions.
Conclusions:
- Minimally invasive interventions targeting the regenerative microenvironment hold promise for early OA.
- Platelet-rich plasma (PRP), MSCs, and exosomes are key regenerative therapies to consider for OA.
- Further research into MSC-based therapies could offer new avenues for OA treatment and reversal.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
