- Abstract
- Natural biopolymers have attracted considerable attention in a variety of biomedical applications. Herein, tempo-oxidized-cellulose nanofibers (T) were incorporated into sodium alginate/chitosan (A/C) to reinforce the physicochemical properties and further modified with decellularized skin extracellular matrix (E). A unique ACTE aerogel was successfully prepared, and its nontoxic behavior was validated using mouse fibroblast L929 cells. In vitro hemolysis results revealed excellent platelet adhesion and fibrin network formation abilities of the obtained aerogel. A high speed of homeostasis was attained based on the quick clotting in <60 s. Skin regeneration in vivo experiments were conducted using the ACT1E0 and ACT1E10 groups. In comparison to ACT1E0 samples, ACT1E10 samples demonstrated enhanced skin wound healing with increased neo-epithelialization, increased collagen deposition, and extracellular matrix remodeling. ACT1E10 was found to be a promising aerogel for skin defect regeneration due to its improved wound-healing ability.
