hAMSCs and hAMSC-CM inhibited heat stress-induced apoptosis and promoted proliferation of skin cells in vivo. a Estimation of apoptosis in sections from day-7 and day-14 skin tissues of normal, PBS, hAMSCs, H-DMEM, and hAMSC-CM groups by using the TUNEL assay. b Proliferation of skin cells was determined by immunohistochemistry using antibodies against PCNA in sections from day-7 and day-14 skin tissues of the PBS, hAMSCs, H-DMEM, and hAMSC-CM groups. (C) Western blot analysis of PCNA protein levels in day-7 and day-14 skin tissues of the PBS, hAMSCs, H-DMEM, and hAMSC-CM groups. d Representative immunofluorescence images of CK19 expression for re-epithelialization in skin tissues. e Western blot assay for CK19 expression in skin tissues at 7 days and 14 days after treatment
