Adipose-Derived Stem Cells Exosomes Improve Fat Graft Survival by Promoting Prolipogenetic Abilities through Wnt/β-Catenin Pathway

hADSC-Exo enhanced the survival rate of fat grafts in the nude mouse model. (a) The design of the nude mouse model. (b) Gross observation of the fat grafts demonstrated that the hADSC-Exo group (the right side of each picture) had larger graft sizes compared with that in the HFF-Exo group (the left side of each picture). (c–f) Harvesting the fat grafts at 1, 2, and 3 months after fat transplantation, the weight and volume of fat grafts were significantly better in the hADSC-Exo group compared to the HFF-Exo group (, , and ).
