Bilobalide induces autophagy in IL-1β-induced ATDC5 chondrocytes. (A,B) Western blot analysis of LC3II protein expression after IL-1β induced cartilage for different periods. (C,D) The number of autophagosomes was observed using MDC dye under a fluorescence microscope. Magnification ×10. (E) Autophagic vesicles were observed using transmission electron microscopy. Magnification ×3000. All data were presented as mean ± SD (n = 3). ** p < 0.01 compared to the control group; #p < 0.05 and ##p < 0.01 compared to the IL-1β group (Statistical analysis using one-way ANOVA and paired two-tailed Student’s t-test).
