  Fig. 2. Expression of Xnot2 and Xbra in the blastopore lip and tailbud. Top row: Xnot2 whole-mount in situ hybridizations. Bottom row: Xbra hybrididizations. (a,A') Expression of Xnot2 is restricted to the prospective notochord and dorsal lip (A,B), whereas Xbra is expressed in the propective notochord and the entire circumblastoporal region.
