Figure Lengend Snippet: Effects of Hypo-BMSCs-Exos on IL-1β-induced chondrocyte senescence. A: Immunofluorescence staining revealed changes in p16, p21, and p53 in IL-1β-induced chondrocytes following intervention with Norm-BMSCs-Exos and Hypo-BMSCs-Exos. B: Quantitative analysis of immunofluorescence staining. C: Western blot detection of p16, p21, and p53 expression in chondrocytes. D: Statistical analysis of gray values and relative values for corresponding protein bands. E: SA-β-gal activity in chondrocytes across different groups assessed using SA-β-gal staining kit, bar = 75 μm. F: Counting and statistical analysis of SA-β-gal positive cells in chondrocytes across groups. G: Flow cytometry analysis of mean fluorescence intensity for reactive oxygen species (ROS). H: Statistical analysis of ROS expression levels across groups. Results are presented as Mean ± SD. Intergroup statistical significance is indicated as: ∗P < 0.05, ∗∗P < 0.01, ∗∗∗P < 0.001 (n = 3).

Article Snippet: The cells were then washed three times with PBS, with each wash lasting 5 min. After blocking with bovine serum albumin (BSA) for 20 min at room temperature and subsequent washing with PBS, the cells were incubated overnight at 4 °C with primary antibodies against iNOS (Servicebio, China), COX2 (Servicebio, China), Collagen II (Bisso, China), aggrecan (Bisso, China), ADAMTS-5 (Bisso, China), MMP-13 (Affinity, USA), p16 (Abcam, USA), p21 (Affinity, USA), and p53 (Proteintech, USA).
