Mesenchymal Stromal/Stem Cells in Regenerative Medicine and Tissue Engineering

Area of Science:

• Cell Biology
• Regenerative Medicine
• Tissue Engineering

Background:

• Mesenchymal stromal/stem cells (MSCs) have been investigated for over 50 years.
• MSCs are recognized for their multipotency, perivascular identity, immunomodulation, and angiogenic signaling capabilities.

Purpose of the Study:

• To review the history and evolution of MSC research.
• To discuss MSC developmental origins and differentiation potential.
• To highlight clinical applications, considerations, and risks associated with MSCs.

Main Methods:

• Literature review of MSC research spanning five decades.
• Synthesis of findings on MSC multipotency, perivascular identity, immunomodulation, and angiogenesis.
• Discussion of developmental origins, differentiation capacity, and clinical use considerations.

Main Results:

• MSCs possess multipotent differentiation capacity.
• MSCs exhibit significant immunomodulatory and angiogenic properties.
• The perivascular niche is increasingly recognized as the in vivo identity of MSCs.

Conclusions:

• MSCs are a versatile cell source with broad therapeutic potential in regenerative medicine and tissue engineering.
• Further research is needed to fully elucidate MSC developmental origins and therapeutic mechanisms.
• Careful consideration of isolation, expansion, and clinical use is crucial for safe and effective MSC-based therapies.
