An Overview on Mesenchymal Stem Cells Derived from Extraembryonic Tissues: Supplement Sources and Isolation Methods

Area of Science:

• Regenerative Medicine
• Stem Cell Biology
• Tissue Engineering

Background:

• Extraembryonic tissues are abundant sources for mesenchymal stem cells (MSCs).
• Isolation methods aim for maximum yield of viable and functional cells.
• MSCs from these sources exhibit low immune-rejection potential.

Purpose of the Study:

• To comprehensively review and update methods for isolating MSCs from human extraembryonic tissues.
• To assess the efficacy of different isolation techniques.
• To highlight the potential of these MSCs in clinical applications.

Main Methods:

• Review of literature on MSC isolation from cord blood, amniotic fluid, placenta, and umbilical cord.
• Analysis of reported cell yields, viability, and functional characteristics.
• Evaluation of differentiation potential and clinical trial data.

Main Results:

• Extraembryonic tissues provide a readily accessible source of MSCs via non-invasive isolation.
• These MSCs demonstrate significant differentiation capacity into various cell types.
• Clinical trials are exploring their therapeutic use in conditions like cartilage, lung, liver, and neural disorders.

Conclusions:

• MSCs derived from extraembryonic sources are promising for therapeutic applications.
• Established protocols allow for isolation, expansion, and cryopreservation in cell banks.
• Further research and clinical trials are warranted to fully harness their regenerative potential.
