Fig. 1From: Bone marrow mesenchymal stem cells attenuate the progression of focal segmental glomerulosclerosis in rat modelsCharacterization of rat BMSCs. a Morphological observation of the adherent P3 cells under an inverted microscope. b Adipogenic differentiation of BMSCs: BMSCs were cultured for 21 d alternately in adipogenic induction medium. Lipid droplets were visualized by Oil Red O staining. c Osteogenic differentiation of BMSCs: cells were cultured for 21 d with osteogenic induction medium, and calcium deposits were visualized by Alizarin Red staining. a-c I: original magnification × 40; a-c: II, original magnification × 200Back to article page
