In vivo evaluation of cartilage repair in rats. A Schematic illustration of the surgical procedure in which rASCs were encapsulated in GelMA/PAMAM-MA hydrogel and injected into the articular cartilage defects of rats. B ICRS visual histological assessment score of the normal control group, blank control group, GelMA + rASCs group and GelMA/PAMAM-MA + rASCs group. C General views of rat knee joint specimens of the four groups obtained after repair for 8 weeks. D and E Histological images of H&E staining (D) and safranin-O/fast green staining (E) of rat cartilage defects in the four groups. Scale bars: 500 μm. Error bar: Mean ± SD, * represents p < 0.05
