Histological observation. a, d, and g The empty group in which the wound was not filled; b, e, and h the control group in which the wound was filled with silica nanospheres plus GelMA gel; and c, f, and i show the SrR group in which the wound was filled with SrR-loaded silica nanospheres plus GelMA gel. Toluidine blue staining (d, e, and g) and safranin O/fast green staining (g, h, and i) revealed that the SrR group had a better cartilage tissue repair effect and significantly higher ICRS-II scores than the other two groups (j). There were significant differences of ICRS-II scores between the empty group, control group, and SrR group (P< 0.05)
