Fig. 1From: Notch1 activation of Jagged1 contributes to differentiation of mesenchymal stem cells into endothelial cells under cigarette smoke extract exposureDynamic changes in morphology, marker expression, and function of mesenchymal stem cells (MSCs) as they differentiate into endothelial-like cells after standard induction. A Induced MSCs retained a spindle-shaped morphology until day 3 and looked similar to rat aortic endothelial cells (ECs) after 14 days of induction (× 100). B vWF was detectable after 14 days of induction. However, we found only marginal expression of vWF in undifferentiated MSCs (× 400). C Induced MSCs showed tube-forming potential after culture in Matrigel for 24 h (× 200). i-MSC: induced MSCBack to article page
