Biomaterial-assisted cell therapy in osteoarthritis: From mesenchymal stem cells to cell encapsulation

Area of Science:

• Regenerative Medicine
• Biotechnology
• Orthopedics

Background:

• Osteoarthritis (OA) is a degenerative joint disease causing pain and cartilage damage.
• Current OA drugs offer symptomatic relief but do not prevent disease progression.
• Mesenchymal stem/stromal cells (MSCs) possess therapeutic properties including immunomodulatory and anti-inflammatory effects.

Purpose of the Study:

• To review the therapeutic potential of MSCs for osteoarthritis (OA).
• To explore MSC encapsulation as a strategy to enhance OA treatment.
• To highlight advances in using encapsulated MSCs for OA therapy.

Main Methods:

• Review of current literature on MSCs and their application in OA.
• Discussion of MSC properties and limitations of intra-articular injection.
• Analysis of MSC encapsulation techniques and their benefits for OA treatment.

Main Results:

• MSCs secrete bioactive factors with potent therapeutic effects relevant to OA.
• Intra-articular injection of MSCs faces challenges like cell death and leakage.
• MSC encapsulation offers a promising solution to improve cell survival and targeted delivery for OA.

Conclusions:

• MSCs hold significant therapeutic potential for osteoarthritis.
• Encapsulation is a key strategy to overcome MSC delivery limitations in OA.
• Advances in MSC encapsulation pave the way for improved OA treatment modalities.
