Mesenchymal stem cells (MSCs) are defined as multipotent cells that can give rise to various kinds of differentiated mesenchymal cells, and are thus considered to be useful for clinical therapy. However, the big hurdles of MSC therapy are the inability of MSCs to reach the appropriate tissues or sites with high efficiency and engraftment after transplantation. In this study, we investigated how adipose tissue-derived MSCs (AT-MSCs) improve their homing ability after intravenous injection. We previously found that human endothelial progenitor cells with low aldehyde dehydrogenase activity (Alde-Low EPCs) are suitable for the treatment of ischemic tissues. In addition, we demonstrated that microvesicles (MVs) derived from Alde-Low EPCs possessed the ability to improve the homing ability of non-functional Alde-High EPCs, resulting in wound healing. We initially transfected MVs derived from Alde-Low EPCs (EMVs) to human AT-MSCs, which were originally unable to cure ischemic tissues by intravenous transplantation. Remarkably, AT-MSC transfected EMVs dramatically repaired the ischemic skin flap compared with AT-MSC derived-MV (MMVs) transfected AT-MSCs or control AT-MSCs. We then found that the expression of CXCR4, an important chemokine receptor for cell migration, was highly elevated in EMV-transfected AT-MSCs. Moreover, AT-MSCs transfected with EMVs, but not control AT-MSCs, migrated to wound sites after intravenous injection. Consequently, CD45(+) inflammatory cells were successfully recruited at the wound sites after the injection of EMV-transfected AT-MSCs. These results demonstrate that EMVs are a useful source to improve the homing ability and wound healing ability of MSCs at the wound sites.
