Mesenchymal stem cells in drug/gene delivery: implications for cell therapy

Area of Science:

• Regenerative Medicine
• Stem Cell Biology
• Immunology

Background:

• Hematopoietic stem cell transplantation has a long history.
• Adult stem cells, particularly mesenchymal stem cells (MSCs), are emerging as potential therapeutics for diverse diseases.
• MSCs are sourced from bone marrow, umbilical cord, and adipose tissue.

Purpose of the Study:

• To review the therapeutic potential and emerging properties of mesenchymal stem cells (MSCs).
• To discuss the potential neuroectodermal origin of MSCs and their in vivo transformation status.
• To highlight the utility of MSCs in targeted drug delivery and their immunomodulatory functions.

Main Methods:

• Literature review of current research on mesenchymal stem cells (MSCs).
• Analysis of MSC differentiation, origin, and immunomodulatory properties.
• Examination of MSC applications in targeted therapeutics for cancer, cardiovascular, and neurodegenerative diseases.

Main Results:

• MSCs exhibit immunosuppressive properties, enabling 'off-the-shelf' applications.
• MSCs possess chemotactic receptors for migration to injury sites, facilitating targeted delivery.
• Evidence suggests MSCs may be neuroectodermal, contrasting with earlier mesodermal assumptions.

Conclusions:

• MSCs offer significant therapeutic potential due to their immune privilege, low tumorigenicity, and ability to act as cellular vehicles for targeted drug delivery.
• Further research is needed to fully understand MSCs' in vivo behavior and confirm their origin.
• MSCs present a promising avenue for treating serious diseases with limited therapeutic options.
