Allogeneic Adipose-Derived Stem Cells Protect Fat Grafts at the Early Stage and Improve Long-Term Retention in Immunocompetent Rats

Background Syngeneic adipose-derived stem cells (ASCs) promote the survival of fat grafts. But it is unclear whether allogeneic ASCs have a similar protective effect. In this study, we investigated the protective effect of allogeneic ASCs in a fat graft model of immunocompetent rats.
