Figure 3. Fisetin treatment specifically remove senescent macrophages from mdx/utro(−/−) mouse. (A) Real time-PCR result of gene expression level of SASP factors, p16 and IL-10 in WT and mdx/utro(−/−) macrophages (n = 3 cell lineages). (B) Staining of SA-β-Gal in 4 groups of macrophages with fluorescent Senescence Assay Kit. Fisetin was applied to treat the WT and mdx/utro(−/−) macrophages for 48 hr at 20 μM of concentration. (C) Statistics of SA-β-Gal+ cells in 4 groups of cells. n = 6 (3 cell lineages x 2 replicates/group). Data are presented as mean +/− SD.
