<p>(A) The biomaterial manufacture, skin culture and mouse skin wound healing model. (B) Proposed schematic presentation of collagen (0.6%, w/v, 93.75 mM), HA (0.01%, w/v, 0.05 mM), gelatin (1%, w/v, 2 mM) cross-linked by EDC. (C), (D) SEM of collagen/HA/gelatin scaffolds. The pore size was 132.5±8.4 μm.
