hBM-MSC-Ex promotes proliferation in HaCaT and HDF skin cells. The cell proliferation curve were shown from respective HaCaT and HDF skin cells after treated with hBM-MSC-Ex (a, b). Immunofluorescent staining was performed in HaCaT and HDFs for PCNA-positive cells, and representative images were shown (c). The quantification of PCNA-positive cells (in percentages) in HaCaT and HDFs were determined (d). HaCaT, human keratinocytes; HDFs, human dermal fibroblasts; bar = 100 μm, *p < 0.05, **p < 0.01, n = 3; data are reported as mean ± SD
