Fig. 2From: Distinct chemical composition and enzymatic treatment induced human endothelial cells survival in acellular ovine aortaeImmunofluorescence imaging of decellularized ovine aortae with DAPI (a, b). 7-day incubation of samples with decellularization buffer and enzymatic treatment (b) yielded in cell nuclei removal from vascular intima and media layer compared to the control sample (a). Verhoeff-Van Gieson staining revealed a decrease of elastin fibers (black strands) in decellularized samples while levels of collagen fibers (yellow fibers) remained unchanged (c, d)Back to article page
