Fig. 1From: Distinct chemical composition and enzymatic treatment induced human endothelial cells survival in acellular ovine aortaeThe appearance of ovine aortae pre- and post-decellularization of day 7 (a, b). Hematoxylin–Eosin staining revealed a large number of cell nuclei in the tunica media layer while 7-day incubation of ovine aortae with decellularization solution and enzymatic treatment eliminated cell nuclei (c, d)Back to article page
