毛细血管的再生 • Enzymatic dissolution of the basement membrane of existing capillaries. • Endothelial cells proliferate, migrate, and begin to form vascular channels. • The channels join adjacent capillaries to form a series of vascular channels. At first, the newly formed vessels have gaps between the endothelial cells and a poorly formed basement membrane. • Some vessels become arterioles. Others enlarge to form thin-walled venules
