Effects of the hFSSC secretome on proliferation of HUVEC. a Immunofluorescent staining of antibody on HUVEC. b Percentages of Ki-67-positive cells in HUVEC. c The proliferation curves of HUVEC using hFSSC secretome. Note that hFSSC secretome group showed the highest percentage of Ki-67-positive cells and proliferation rate compared to the other two groups. HUVEC, human umbilical vascular endothelial cell; SFM, serum-free medium; hUCMSC, human umbilical cord mesenchymal stem cell; hFSSC, human fetal skin stem cell. *p < 0.05, **p < 0.01, ***p < 0.001, when compared to SFM; bar = 200 μm; data, n = 3; mean ± SD
