  Fig. S3. In situ hybridization analysis of xMID morphants. (A-Z) Dorsal views of unilaterally injected morphants at stage 14-15; anterior is to the top. Morpholinos were injected into the right dorsal blastomere at the four-cell stage. Sox2 (A,B), NCAM (C,D) and N-cadherin (E,F) are pan-neural markers. Epidermal keratin (G,H) is an epidermal marker. HNF3β (FoxA2a) (I,J) and Pintallavis (FoxA4a) (K,L) are floor-plate markers. N-tubulin (M,N) is a marker for differentiated neurons. Shroom3 (O,P) is the essential regulator of apical constriction. Pax3 (Q,R) is a dorsal neural marker. Sonic hedgehog (Shh) (S,T), a key molecule for neural dorsoventral patterning, is expressed in the floor plate. Ptc2 (U,V) and Gli1 (W,X) are downstream targets in the Shh pathway. Gli3 (Y,Z) is a transcription factor mediating the Shh pathway. The expression patterns of all the markers in the xMID morphants were similar to those in control-Mo-injected embryos, except that the expression domains were wider than in the controls at given stages because of the delayed neural tube closure.
