Figure Lengend Snippet: Bone regeneration after implantation with different hydrogels substitute into rat femoral defects in vivo . (A) Coronal, sagittal, and 3D reconstruction of femoral. (B) Quantitative results of BV/TV in the femoral condyle defects based on micro-CT. (C–D) H&E and Masson staining of femoral section at 4 weeks after implantation. (E) Fluorescent microscope observation of a typical image of Calcein and Alizarin red staining. (F) Quantitative analysis of the mineral supposition rate at 4 weeks after implantation. Data are presented as the mean ± SEM; n = 3; ∗significant difference between selected groups, ∗ p < 0.05, ∗∗ p < 0.01 and ∗∗∗ p < 0.001.
