Intestinal defects in pik3c3 mutants. a General morphology of WT and pik3c3 mutants at 8 dpf. b In vivo imaging of zebrafish digestive organ with fluorescent reporters. FITC-labeled dextran is used to evaluate the nutrient uptake activity and the quenched fluorescent reporter PED6 or Enzchek is activated only after cleavage by intestinal phospholipase or protease. The digestive functions appear normal in mutants at 7 dpf while they become defective at 8 dpf. Scale bars, 500?µm. Numbers in (a, b) represent (embryos with the indicated phenotype)/(total embryos analyzed). c Hematoxylin?eosin staining of cross sections corresponding to the intestinal bulb or mid-intestine of embryos at 7?8 dpf. Typical intestinal folding is lost and cell shedding can be detected in pik3c3 mutants at 8 dpf. Scale bars, 50?µm. d TEM analyses of IECs. Adherens junctions (arrow) are defective in mutants. Microvilli and cell junctions are severely disrupted in mutants at 8 dpf. Scale bars, 1?µm
