Visualization of vascular structures in CEB by staining for PECAM-1. (a) An attached day 16 CEB showing vascular cords and networks. The growing fronts of the vascular networks (arrows) as well as remodeling (arrow heads) within the vascular cords are clearly visible. (b) A section of a day 19 ‘floating’ CEB showing endothelial cell-lined channels (*). Bars=200 μm.
