Mesenchymal Stem Cell Migration and Tissue Repair

Xiaorong Fu et al. Cells. .

Abstract

Mesenchymal stem cells (MSCs) are multilineage cells with the ability to self-renew and differentiate into a variety of cell types, which play key roles in tissue healing and regenerative medicine. Bone marrow-derived mesenchymal stem cells (BMSCs) are the most frequently used stem cells in cell therapy and tissue engineering. However, it is prerequisite for BMSCs to mobilize from bone marrow and migrate into injured tissues during the healing process, through peripheral circulation. The migration of BMSCs is regulated by mechanical and chemical factors in this trafficking process. In this paper, we review the effects of several main regulatory factors on BMSC migration and its underlying mechanism; discuss two critical roles of BMSCs-namely, directed differentiation and the paracrine function-in tissue repair; and provide insight into the relationship between BMSC migration and tissue repair, which may provide a better guide for clinical applications in tissue repair through the efficient regulation of BMSC migration.

Keywords: differentiation; mechanochemical regulation; mesenchymal stem cells; migration; paracrine; tissue repair.

Proposed schematic diagram of the relationship between BMSC migration and tissue repair. Once BMSCs sense the injury signal released from damaged tissue, they migrate from bone marrow into the injured tissue through peripheral circulation, which is regulated by multiple mechanical and chemical factors. After reaching the damaged tissue site, BMSCs perform wound healing of damaged tissues through two key roles: the paracrine mechanism and/or directed differentiation.
