Figure 11: Effects of cmAFSCs and cmADSCs on the proliferation (Ki-67) of HDF-27and HDF-73. Fibroblasts were treated with or without TGFβ1 and in combination with either CM of AFSCs or ADSCs for 48 h. (A) Representative immunofluorescence stainings and (B) quantification of the % of cells positive for Ki-67 in HDF-27 and HDF-73. White scale bar represents 200 μm.
