Proangiogenic effects of hADSC-Exo in vitro. (a) The CCK8 revealed that 100 μg/mL of hADSC-Exo had the most significant promotion effect on the proliferation of HUVEC, and this promotion effect persisted with increasing culture time. (b, c) The expression levels of VEGFA genes in fat grafts were treated with hADSC-Exo or HFF-Exo. (d) Proliferating HUVECs were stained with red fluorescence, and all nuclei were stained with blue fluorescence. (e) The cell proliferation rate of hADSC-Exo group was higher than that of HFF-Exo group. (f, g) The migration of HUVEC in the hADSC-Exo group was better than that in the HFF-Exo group. ().
