Fig. 7. Islet1 and Islet2 can function redundantly in PMN formation. (A-D) 28 hpf embryos stained with zn1 and znp1 (green) Abs. CaP axons are indicated by arrowheads; MiP axons are indicated by arrows. Control embryos (A) have normal CaP axons. Embryos co-injected with islet2 RNA and islet1 MO (B) have normal CaP axons. Control embryos (C) have dorsally projecting MiP axons. MiP axons are present in embryos co-injected with islet1 MO and islet2 RNA (D). Scale bar: 20 µm.
