TNBS induced IBD phenotypes in zebrafish. A, B The intestinal distribution of red fluorescent-labeled neutrophils in control, TNBS and 5-ASA treated embryos; at least 6 embryos were examined for each group. C, D ROS staining (green signals) in control, TNBS and 5-ASA treated embryos; at least 5 embryos were examined for each group. E HE staining of embryo cross sections. The intestine regions were circled by yellow dotted lines. Scale bar: 100 μm. #compared with the control group; *compared with the model group; # or *, p < 0.05, ## or **, p < 0.01
