Abstract

CHyCoGel, a novel injectable hydrogel scaffold, supports high cell viability and promotes significant wound healing.

  • CHyCoGel is composed of chitosan, hyaluronic acid, chondroitin sulfate, and an amphiphilic stabilizer.
  • Primary dermal fibroblasts isolated from neonatal rat skin exhibit well-organized cytoskeletal structures when grafted into CHyCoGel.
  • Gene modulation related to tissue remodeling is observed, including increased expression of α-SMA, fibronectin, Col1A1, and TGF-β.
  • Application of PDF-loaded CHyCoGel enhances wound healing, epithelialization, and the regeneration of skin appendages.
  • CHyCoGel promotes angiogenesis by upregulating VEGF and supports balanced remodeling through enhanced type I collagen expression.
