Injection of Smad7 (2 ng) into the A4 blastomere induces Sox3 (A–C), Sox2 (D–E), Chordin (H–J) and Brachyury (K–L), but not Six3 (F–G). C, J. Histological sections through the levels indicated in B and I, respectively. A, D, F, H and K are dorsal views. B, E, G, I and L show ventral views of the embryo to their left.
