Polymer coating and mechanical test. (A) Chemical structure of 8g7 polymer. (B) Scanning electron microscopy image of glass coverslip coated with the 8g7 polymer (white arrows). (C) Transmission electron microscopy image of polymer-coated decellularized artery section. Polymer coating (white arrows). (D) Mechanical analyses of native arteries (NA), decellularized arteries (DA) and polymer-coated decellularized arteries (PDA). Measurements of mean burst pressure, load and ultimate tensile strength are compared between artery groups(*P < 0.05), (**P < 0.01).
