Abstract

Regenerative therapy with keratinocyte growth factor (KGF) is a novel therapeutic approach for treatment of chronic wounds. However, KGF cannot be used directly to the wound site due to its physicochemical instability. In previous study, sacran, a natural megamolecular polysaccharide, showed potential properties as a biomaterial for hydrogel film in wound healing. In this study, we fabricated sacran hydrogel film containing KGF (Sac/KGF-HF) and evaluated the effects of Sac/KGF-HF on fibroblasts migration and re-epithelialization process. We successfully prepared a homogenous and -amorphous Sac/KGF-HF by a casting method. In addition, Sac/KGF-HF had a high swelling ratio and flexibility. Sac/KGF-HF promoted a migration process of NIH3T3 cells and improved wound healing ability in mice with a percentage of wound closure reaching 90.4% at 9 d. Interestingly, the addition of KGF in Sac-HF considerably increased the number of epithelial cells compared to control, which is important in the re-epithelialization process. It could be concluded that KGF in Sac-HF has the potential for promoting Sac-HF abilities in wound healing process.
