Promotion of the development of colonic organoids by Tsc2 ablation. (a) Representative phase-contrast images of colonic organoids derived from the colon of 9- to 13-week-old control or Tsc2 CKO mice at 1, 3, 5, 7, and 9 days after cell plating. The white arrowheads indicate cryptlike buds. Scale bar, 100 μm. (b) Immunofluorescence analysis of Ki67 (red) and β-catenin (green) in colonic organoids cultured for 7 days as in (a). Scale bar, 100 μm. (c) The number of colonoids was determined as a percentage of colonic organoids at 3 days after cell plating as in (a). Data are means ± s.e. for a total of 105 (control) or 119 (Tsc2 CKO) organoids in three independent experiments. *P < 0.05 (Student’s t test). (d) The number of buds per colonic organoid was determined at 9 days after cell plating. Data are means ± s.e. for a total of 38 (control) or 28 (Tsc2 CKO) organoids in three independent experiments. ***P < 0.001 (Student’s t test).
