Umbilical Cord Mesenchymal-Stem-Cell-Derived Nanovesicles as a Novel Strategy to Promote Wound Healing in Diabetes

Investigators constructed a method to produce umbilical cord mesenchymal stem cell-derived nanovesicles (UCMSC-NV) by serial extrusion through filters, and investigated the effects of UCMSC-NV on wound healing in vivo and in vitro, as well as the potential mechanisms.
