Physicochemical characterization of methacrylated gelatin-exosomes (GelMA-Exos) and GelMA. a The GelMA hydrogel was colorless and transparent. b GelMA hydrogels could be applied via a syringe. c GelMA and GelMA-Exos observed via scanning electron microscope. d A Fourier transform infrared spectrometer (FTIR) was used for GelMA hydrogels and GelMA-Exos separately. e X-ray diffraction (XRD) tests were performed on GelMA hydrogels and GelMA-Exos separately. f The storage modulus and loss modulus of GelMA and GelMA-Exos measured using a rheometer
