Fig. 2. Scanning electron micrographs. (A) The endothelial cells of the basilar artery bifurcation were fusiform in the sham operation group; (B) 1.5 months after bilateral common carotid artery ligation, the endothelial cells of basilar artery bifurcation were morphologically changed from fusiform to column shape; (C) three months after bilateral common carotid artery ligation, the endothelium presents wide gaps between the endothelial cells (ECs), and ECs and endothelial cell nucleus showed margination.
