Figure Caption

Fig. 8 Smooth muscle and enteric neurons in ascl1a-/- at 4–5 dpf. Smooth muscle within the digestive system appears normal from proximal ((B) compared to (A)) to distal ((D) compared to (C)) in ascl1a−/− 5 dpf embryos as determined by desmin immunohistochemistry. Neuronal cell bodies highlighted by Elav 1 are numerous in both the proximal (E) and distal (G) WT intestine at 5 dpf but have been severely reduced in the proximal (F) and distal (H) ascl1a-/- intestine. Neurite density is also severely reduced in both the proximal (J) and distal (L) ascl1a-/- intestine when compared to WT proximal (I) and distal (K) as shown with acetylated tubulin. Scale bars represent 50 μm.
