Embryos injected with cldne-morpholino oligonucleotide (MO) exhibit epiboly delays. Lateral views of live embryos, injected construct indicated in lower right. A,B: Uninjected embryo at 30% epiboly (A), time matched cldne-MO injected embryo at sphere stage (B). C-E: Uninjected embryo at shield stage (C), time matched cldne-MO injected embryo at 40% epiboly (D), same embryo as in D (E), arrow indicates the yolk syncytial layer (YSL) nuclei, which have compacted normally. F: Shield stage embryo injected with mismatch morpholino. G: Shield stage embryo injected with cldne RNA. H: Rescued embryo injected with cldne RNA and cldne-MO. I,J: Uninjected embryo at 90% epiboly stage (I), time matched cldne-MO injected embryo at 70% epiboly (J).
