Fig. 3From: Regenerative and protective effects of dMSC-sEVs on high-glucose-induced senescent fibroblasts by suppressing RAGE pathway and activating Smad pathwayCharacteristics of dMSCs. A Bright-field microscope image of colonies formed by dMSCs. Scale bar = 50 μm. B Flow cytometric analysis of cell surface markers. C (a) Calcification assessed by Alizarin Red S staining of dMSCs. C (b) Lipid droplet formation stained by Oil Red in dMSCs after adipogenic induction. Scale bar = 50 μm. C (c) Chondrogenic differentiation of dMSCs assessed by Alcian blue stain.
