[Gene therapy based on human mesenchymal stem cells: strategies and methods]

Area of Science:

• Biotechnology
• Stem Cell Biology
• Gene Therapy

Background:

• Human mesenchymal stem cells (hMSC) are multipotent cells with significant therapeutic potential.
• Efficient and controlled genetic modification of hMSC is crucial for advancing their clinical applications.
• Various viral vectors are employed for transgene delivery into hMSC, each with distinct characteristics.

Purpose of the Study:

• To review and compare major technologies for transient and stable transgene expression in hMSC.
• To evaluate the properties and transduction efficiencies of different viral vectors in hMSC.
• To outline the diverse applications of hMSC transgenesis in research and therapy.

Main Methods:

• Comparative analysis of established viral vector systems.
• Review of literature on lentiviruses, adenoviruses, adeno-associated viruses (AAV), and baculoviruses for hMSC transduction.
• Assessment of vector properties including efficiency, safety, and integration potential.

Main Results:

• Different viral vectors exhibit varying efficiencies and properties for hMSC transduction.
• Lentiviruses, adenoviruses, AAV, and baculoviruses offer distinct advantages and disadvantages for transgene delivery.
• Transient and stable expression can be achieved depending on the vector system and application.

Conclusions:

• The choice of viral vector is critical and depends on the specific application for hMSC transgenesis.
• Understanding vector properties is essential for optimizing gene delivery for directed differentiation, functional enhancement, and disease correction.
• Transgenesis in hMSC holds promise for both basic research and therapeutic interventions.
