Abstract

The use of stem cells in the treatment of various diseases and injuries has received increasing interest over the past decade. Injected stem cells, such as mesenchymal stem cells, stimulate tissue repair largely through the secretion of soluble factors that regulate various processes of tissue regeneration, including inflammatory responses, apoptosis, host cell proliferation, and angiogenesis. Recently, it has become apparent that stem cells also use membranous small vesicles, collectively called microvesicles (MVs), to repair damaged tissues. MVs are released by many types of cells and exist in almost all types of body fluids. MVs serve as a vehicle to transfer protein, mRNA, and miRNA to distant cells, altering the gene expression, proliferation, and differentiation of the recipient cells. Although animal models and in vitro studies have suggested promising applications for MV-based regeneration therapy, its effectiveness and feasibility in clinical medicine remain to be established. Further studies of the basic mechanisms responsible for MV-mediated tissue regeneration could lead to novel approaches in regenerative medicine.
