Fig. 7. Xdsh-D2 inhibits convergent extension in XBF-2-expressing animal caps. (A) Control uninjected animal caps do not elongate (n=0/40). (B) Animal caps injected with 0.5 ng of XBF-2 elongate as a result of neural convergent extension. Some caps elongate significantly (left); others elongate slightly (middle); and some caps fail to elongate (right). 45% of caps elongated to some degree; n=55. (C) Co-expression of 1 ng of Xdsh-D2 with 0.5 ng of XBF-2 strongly suppresses elongation in all caps. Very weak elongation (see caps at far left) was observed in only 7% of caps (n=45).
