Subcutaneous implantation assay was used to evaluate the angiogenic ability of bionic membrane in vitro. (A) Schematic diagram of subcutaneous implantation experiment. (B) H&E staining was performed on day 10 (black arrows indicate neovascularization and M represents bionic membrane). (C) Representative images of immunofluorescence staining for CD31(red) and VEGF (green), and (D) the fluorescence intensity of CD31 in each field. (n = 6 **p < 0.01, ****p ​< ​0.0001)
