Fig. 5From: In vivo performance of electrospun tubular hyaluronic acid/collagen nanofibrous scaffolds for vascular reconstruction in the rabbit modelVascular grafts fabricated with cellularized tubular HA/collagen nanofibrous scaffold facilitates vascular reconstruction. H&E staining (a), VVG staining (c) and fluorescent staining (f) the cross-section of a retrieved tubular HA/collagen nanofibrous grafts 6 weeks after transplant at 10\(\times \) (a, c, f) compared with rabbit carotid artery (b, d, g). Scale bars, 20 μm. Fluorescence relative to vascular ECs (red), SMCs (green) and nuclei (blue). Quantification of the percentage of elastin area (e), CD31- (h) and α-SMA-positive (i) in the retrieved explants 6 weeks after transplant and carotid artery (n = 3). *p \(<\) 0.05, **p \(<\) 0.01Back to article page
