Fresh Collection of Umbilical Arteries from C‐Section Ensure Endothelial Integrity. (a) Sections obtained from a single umbilical artery were stored at the noted temperature and stained with fluorescent CD31 (green) to visualize endothelium over time. (b) Sections from a single umbilical artery show endothelial cell coverage and cellular junctions at increasing magnification (10x, 40x, and 100x). Vessels are stained for CD31 (green) and VE‐cadherin (red) at 3 hours after C‐section; vessels were stored at 4˚C prior to staining. All scale bars are 20 μm
