Characteristics of PlaMSCs. a Bright-field microscope image of colonies formed by PlaMSCs. Scale bar = 300 μm. b Oil Red O staining showing lipid droplet formation in PlaMSCs after adipogenic induction. Scale bar = 100 μm. c Calcification assessed by Alizarin Red S staining of PlaMSCs. Scale bar = 300 μm. d Chondrogenic differentiation of PlaMSCs assessed by Alcian blue stain. Scale bar = 100 μm. e Flow cytometric analysis of MSC-related cell surface markers. Dotted line histograms represent cells stained with isotype control IgGs. Solid line histograms represent cells stained with the indicated antigen-specific antibodies
