Figure 1

Up-regulation of Hoxb4 expression in the neural tube at 5 to 22 somite stages. (A-F) Whole-mount embryos stained for Hoxb4 at 5 to 22 somites stages (5S to 22S) as indicated. Up to the 5 somite stage, the anterior boundary of expression is located at the 6th somite level both in the neural tube and paraxial mesoderm (A, arrow). At 6–10 somite stages, expression in the neural tube exclusively extends anteriorly while mesodermal expression remains at the same level (B-E). At the 22 somite stage, the expression shows its anterior most boundary at the rhombomere 6/7 level (F). Arrowheads indicate the prospective rhombomere 6/7 boundary. Scale bars; 200 μm.
