Figure Lengend Snippet: In vitro chondrogenic assays. (a) Alcian blue staining of rBMSC cultured SF-PFS-KGN scaffolds after 14 days of culture in chondrogenic medium (scale bar = 3 mm). (b) Quantification of Alcian blue staining by measuring the absorbance of the eluent at 630 nm. (c) RT-qPCR results of mRNA expression of COL Ⅱ, ACAN, and Sox9 in rBMSC cultured scaffolds after 3, 7, and 14 days. (d) H&E and COL II staining of rBMSC cultured scaffolds after 14 days (scale bars = 1000 μm (15x); 50 μm (300x)). Data are presented as mean ± SD, n = 3. ## p < 0.01, ### p < 0.001. Compared with the pristine SF group: ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001.
Article Snippet: The slices were incubated with the primary antibody against COL II (Servicebio) overnight at 4 °C in a wet box.
