| Caption | Conditional inactivation of Neurog3 in only the intestine results in a complete loss of all enteroendocrine cells all along the proximal-distal axis of the intestine. Sections of adult duodenum, jejunum, ileum, and colon were examined for the presence of endocrine cells in control and Neurog3tm1Fgu/Neurog3tm3.1Ggr Tg(Vil1-cre)20Syr/0 or Neurog3tm3.1Ggr/Neurog3tm3.1Ggr Tg(Vil1-cre)20Syr/0 (mutant) animals by immunofluorescence. Images presented are from the jejunum of control (A, C, E, G, and I) and mutant (B, D, F, H, and J) animals and are representative for the general loss of all enteroendocrine cells in mutant animals. Villin-Cre-mediated inactivation of Neurog3 results in a complete loss of all Neurog3+ enteroendocrine progenitors (B), which in wild-type (WT) animals are located in the intestinal crypt compartment (A, arrows). Likewise, mutant animals are also devoid of chromogranin A+ (D), Cck/gastrin+ (F), Glp1+ (H), and Gip+ (J) cells, normally located in the villi of WT mice (arrows in C, E, G, and I), respectively. The age of the animals analyzed is 10-12 weeks. Original magnification, 10. | ||||||||
