Fig. 2From: Engineering biomimetic periosteum with β-TCP scaffolds to promote bone formation in calvarial defects of ratsCell morphologies of rat bone marrow-derived mesenchymal stem cells (rBMSCs) (a) and induced endothelial cells (iECs) (b). Nondifferentiated rBMSCs show a typical spindle shape, while iECs are cobblestone-like and oval. Flow cytometric analysis of CD31 of nondifferentiated rBMSCs (c) and iECs (d). Flow cytometric analysis of CD90 of nondifferentiated rBMSCs (e) and iECs (f). The results indicate that rBMSCs have the ability to differentiate into endothelial cells under experimental conditions.
