Figure 2 ret:GFP⁺ EPCs migrate along the developing gut and populate the gut. At (A) 60 hpf, GFP⁺ EPCs (green arrows) migrate along the developing gut. At (B) 72 and (C) 120 hpf, GFP⁺ ENS cells (white arrows) populate the gut (dashed line). Some of the GFP⁺ cells in the gut are enteroendocrine cells. The GFP⁺ pronephric ducts (pd, magenta arrows) directly overlay the ENS. (A–C): Whole-mount side-views of embryos/larvae at the stage indicated. Dashed line outlines the gut. Scale bar = 100 µm.
