Review: mesenchymal stem cells: cell-based reconstructive therapy in orthopedics

Area of Science:

• Regenerative Medicine
• Tissue Engineering
• Stem Cell Biology

Background:

• Adult stem cells are vital for tissue repair and regeneration.
• Mesenchymal stem cells (MSCs) have been studied for their therapeutic potential.
• Early research utilized embryonic chick limb bud cells to understand differentiation and inductive factors.

Purpose of the Study:

• To review the historical development and advancements in utilizing mesenchymal stem cells (MSCs) for tissue engineering.
• To highlight the development of cell-coating technology for targeted cell delivery.
• To discuss the ongoing challenges and future directions in skeletal tissue regeneration.

Main Methods:

• Historical review of stem cell research from the 1970s to the 21st century.
• Development of techniques for isolating, expanding, and preserving adult bone marrow-derived MSCs.
• Innovation of cell-coating technology ('painting') for targeted protein delivery to cell surfaces.

Main Results:

• Established methodologies for isolating and expanding MSCs with preserved stem cell capacity.
• Demonstrated the use of MSCs with delivery vehicles for repairing various connective tissues.
• Developed a novel cell-coating technology for precise targeting of reparative cells to specific tissue sites.

Conclusions:

• Cell-coating technology represents a significant advance in directing MSCs for tissue repair.
• Perfecting cell-based tissue engineering protocols is key to harnessing the body's regenerative potential.
• Future efforts should focus on integrating scaffolds, bioactive factors, and reparative cells for skeletal tissue regeneration.
