Figure 1: Characterization of the rat ADSCs. (a) FACS analysis revealed that surface antigen expression of ADSCs (P3) was consistent with that of mesenchymal stem cells. Representative images of (b) osteogenic-induced ADSCs with Alizarin red S staining and (c) adipogenic-induced ADSCs with Oil Red O staining. Original magnification is ×100; ADSCs = adipose tissue-derived stem cells; FACS = fluorescence activated cell sorting.
