A, B Toluidine blue stain for immobilized heparin after coating in decellularized scaffold. B In hDA blue stain indicates immobilization of heparin in scaffold. Scanning electron microscopy of DA and hDA vascular scaffold. C, D Cross-sectional scan of DA and hDA (E) inner surface scan of the DA (F) inner surface scan of heparin coating decellularized artery graft after platelet adhesion test. The arrowheads indicate adhered platelets on luminal surface of DA. (L-Luminal area) (G) Hemolysis assay for hDA where distilled water (DW) and 0.9% NaCl (Normal saline NS) were used as positive and negative controls, respectively
