Figure Lengend Snippet: Histological analysis of the tissue around samples. (a) Representative HE staining images of tissue around the samples post implantation for 1 month (the green arrows mark the neutrophil in tissue around samples and the blue arrows mark the newly formed vessels in the tissue around samples). (b) Quantitative bone area calculated by HE (n = 3); (c) Represent Col-II staining images of bone tissue around the samples post implantation for 1 month; (d) Quantitative positive area of Col-II (n = 4). Data are presented by mean with SD. Statistical significance was calculated by one-way ANOVA analysis. **p < 0.01, ***p < 0.001, ****p < 0.0001, compared with SPLA10 in b and d.

Article Snippet: For immunohistochemistry staining, rabbit polyclonal anti-Col-III antibody (Servicebio, GB111629, 1: 500) and rabbit polyclonal anti-Col-II antibody (Servicebio, GB11021, 1: 200), and secondary antibody, HRP-labeled goat anti-rabbit IgG (Servicebio, GB23303, 1: 200), were used to stain Col-III and Col-II, respectively.
