(A) WT and (B, C) some N-cad overexpressing MZembryos have a round shaped pineal morphology indicative of a closed pineal organ. (D, E) Other N-cad overexpressing MZfish have an elongated or divided pineal organ, demonstrating that their NTD has not been corrected. All images are dorsal views with anterior to the top. The background in Panel C has a pink cast because the embryo was too fragile to remove from the yolk. The midline of the brain is apparent in panels A and B, and is indicated by a black line.
