Effects of the ASC-CM on proliferation of HUVECs and NIH-3T3 cells using Ki-67 staining. a Immunofluorescent staining of HUVECs and NIH-3T3 using Ki-67 antibody. b, c Percentages of Ki-67-positive cells in HUVECs and NIH-3T3, respectively. Note that ASC-CM showed the highest percentage of Ki-67-positive cells compared to all four control media in the two cell lines; HUVECs, human umbilical vascular endothelial cells; **p < 0.01, ***p < 0.001, when compared to DMEM; ##p < 0.01, ###p < 0.001, when compared to IGF1; bar = 200 μm; white arrow, Ki-67-positive cells; n = 3; mean ± SD
