Fig. 4. hi2217 mutant epithelial phenotypes at 38 hpf are not mediated by leukocytes. Tailfin views of hi2217 embryos pulse-labeled with BrdU and fixed at 38 hpf; A-F are wild-type siblings, A'-F' are mutants. (A,A',D,D') OCC images and corresponding images of zMPO immunolabeling (B,B',E,E') and BrdU immunolabeling (C,C',F,F') of uninjected (A-C,A'-C') and pu.1 MO-injected (D-F,D'-F') hi2217 embryos. Embryos are oriented anterior to the left, dorsal side up. Bar, 100 µm.
