TLDR Adding insulin-like growth factor 1 and bone marrow-derived stem cells to a collagen-chitosan scaffold helps wounds heal faster and regrows hair follicles.

In this study, the researchers investigated the effects of incorporating insulin-like growth factor 1 (IGF1) and bone marrow-derived mesenchymal stem cells (BM-MSCs) into a collagen-chitosan scaffold on wound healing and hair follicle regeneration. They found that the IGF1- and BM-MSC-incorporating scaffolds promoted wound healing and effectively regenerated hair follicles in a rat model of full-thickness skin injury. The scaffolds also inhibited inflammatory cytokines during wound healing. In vitro experiments showed that IGF1 promoted the proliferation and migration of BM-MSCs. These findings suggest that the topical application of IGF1 and BM-MSCs in collagen-chitosan scaffolds could be a feasible and effective therapeutic approach for improving functional wound healing.

Hair growth can be induced by transplanting certain cells, but these cells lose their properties during culturing. The best cell interaction happens in a liquid medium under gravity, and using collagen doesn't help. Future research could focus on using growth factors to stimulate these cells.
