KLF13 is critical for the maintenance of CD4CD8+CD24 T cells in BALB/c thymus. (A) CD4 and CD8 expression in thymocytes from wild-type and Klf13−/− BALB/c mice. (B) Absolute numbers of CD4+CD8 single positive (CD4+ SP) and CD4CD8+ (CD8+ SP) cells in the thymi of wild-type and Klf13−/− BALB/c mice. P < 0.05 is considered significant. Error bars are SDs. (C) Purified CD4+CD8+ double-positive (DP) cells were differentiated with PMA, ionomycin, and IL-7 to CD8+ SP cells in vitro. (D) Expression of CD24 and TCRβ in the indicated thymic populations from BALB/c and C57BL/6 mice. Gates were based on an isotype control antibody. (E) Expression of CD44 and CD62L in CD4+ SP and CD8+ splenocytes from BALB/c mice. Data are representative of three (B and C) and four (A, C, and E) independent experiments with three mice in each genotype group.
