Figure 10: Effects of cmAFSCs and cmADSCs on the production of intracellular collagen-modifying enzyme PLOD2 in HDF-27 and HDF-73. Fibroblasts were treated with or without CM of AFSCs or ADSCs for 48 h. Representative immunofluorescence stainings and quantification of the % of cells positive for PLOD2 in HDF-27 (upper panel) and HDF-73 (lower panel) are shown. White scale bar represents 200 μm.
