Figure 3. — Expression of senescence related markers. Transwells containing HAMSCs were moved into the correlating wells containing HDFs which accepted 9 J/cm² UVA irradiation. (A) mRNA expression of MMP1 and p53 in UVA irradiated HDFs co-culturing with or without HAMSCs for 72 h. (B) Expression of p53, MMP1 and SIRT1 in UVA irradiated HDFs co-culturing with or without HAMSCs were determined by western blot, GAPDH served as an internal control. Values are means ± SD of 3 independent experiments with each performed in triplicate. ^##P<0.01 vs the HDFs group; **P<0.01 compared with the group treated with UVA alone.
