Figure 3. BMSCs-GSSM-gel accelerated wound healing. (A, B) BMSCs-GSSM-gel greatly improved skin wound healing in rabbit model (6 animals in each group). (C, D) BMSCs-GSSM-gel greatly improved skin wound healing in mouse model (9 animals in each group). (E) HE staining was performed to investigate skin histological changes. (F, G) Collagen deposition was evaluated with Masson’s trichrome and Sirius red staining. *p < 0.05 compared with control group, **p < 0.01 compared with control group, ***p < 0.001 compared with control group.
