“…In addition, chitosan hydrogel applied in the wounds of mice, rats, and pigs accelerates collagen synthesis, re-epithelialization, and angiogenesis [ 40 , 41 , 42 ]. In addition, TCS is known to possess a broad spectrum of antibacterial properties because it can inhibit the synthesis of fatty acid required for the membrane and wall of bacteria at low concentration and disrupt the membrane of bacteria at high concentration [ 7 , 35 , 38 ]. The stage of wound healing is a complex process involving numerous cells and cytokines in the temporospatial relationship [ 43 ].…”
