The preparation and characterization of the silk fibroin patch (SFP) served as exosome-laden scaffolds. a Schematic illustration of the preparation procedure for SF scaffolds. b Physical pictures of silk fibroin solution, SF scaffold, and SFP. c The structure characterizations of SFP, Exo@SFP, and SGM-Exo@SFP detected by scanning electron microscope (upper scale bars: 100 μm, lower scale bars: 1 μm). The red arrows indicated the exosomes loaded on the SFP. d FTIR spectra analysis of SF, SFP, and SGM-Exo@SFP (n = 4/group)
