kitla Morphant Phenocopies kitab5 Survival Phenotype (A) Wild-type larva at 8 dpf. (B) Higher magnification of dorsal melanocyte stripe of 8 dpf wild-type larva with healthy melanocytes (black arrowhead). (C) kitla MO shows fewer melanocytes at 8 dpf, similar to kitab5. (D) Higher magnification of kitla MO showing melanocytes blebbing through the skin (red arrow), characteristic of melanocyte programmed cell death. (E and F) kitlb MO at 8 dpf (E) and higher magnification (F) of kitlb MO 8 dpf, which is indistinguishable from wild-type. (G) Total melanocyte counts show that the survival phenotypes of kitab5 and kitla MO are similar. Scale bars: 100 μm.
