Fig. 1From: Mechanical stretch: physiological and pathological implications for human vascular endothelial cellsMorphological change of human cerebral microvascular endothelial cells (HCMECs). The HCMECs were stained with Alexa 594 (red) for actin, and the nucleus was stained by DAPI (blue). a HCMECs that were not exposed to stretch were rounded in shape. b HCMECs that were exposed to 18Â h cyclic stretch became elongated in shapeBack to article page
