Research Progress on Immunomodulatory Activity and Clinical Application of Mesenchymal Stem Cells-Derived Extracellular Vesicles--Review / 中国实验血液学杂志

ABSTRACT

Mesenchymal stem cells (MSC) have been widely used in tissue regeneration and treatment graft versus host disease (GVHD) and immune diseases due to their self-renewal, multi-differentiation and immunoregulatory potential. However, more and more scholars begin to put weight on the MSC -derived extracellular vesicles (MSC-EV) for its regulation of inflammation and immunity. MSC-EV can activate the relevant signal pathways and regulate the function and biological behaviors of cells via acting on target cells and mediating communication between cells. MSC-EV has important potential clinical applications for its powerful immunomodulatory and hematopoietic regulatory functions. It is considered as a potential therapeutic tool to treat autoimmune diseases and GVHD. This paper reviewed the immunomodulatory activity of MSC-EV as well as the research progress of MSC-EV in hematopoietic stem cell transplantation, and discussed its potential clinical applications in the future.
