Defect in M cell maturation in Sox8−/− results from epithelium-intrinsic defect. (A and B) Organoids from small intestinal crypts of Sox8+/+ and Sox8−/− mice were cultured with or without RANKL for 3 d. (A) Immunostaining images for GP2 (green) on organoids. Bars, 100 µm. (B) qPCR analysis of M cell–associated genes expressed in the organoid cultures. Values are presented as the mean ± SD; **, P < 0.01; *, P < 0.05; n.s., not significant; unpaired two-tailed Student’s t test, n = 3. Data are representative of two independent experiments.
