Fig. 1. Gbx2 is expressed in posterior ectoderm that includes the prospective neural crest. (A-C) Hypothesis of neural crest (NC) induction by the posteriorizing activity of Gbx2. (D-S) In situ hybridization at the indicated stages for the indicated genes. (D-G) Dorsal view, anterior to the top. (H-K) Transverse sections. (L-O) Lateral view, anterior to the left. (P-R) Dorsal view, anterior to the top. Arrowhead, NC; arrow, gap in Gbx2 expression. (S) Detail of the neural fold region in a lateral view, anterior to the top, midline to the right. (T) Summary of Gbx2 and Snail2 expression at stage 16. Anterior to the top, midline to the right. Different tones of purple denote different levels of Gbx2 expression. Blue, NC.
