Fig. 8. Asymmetric expression of Gsc or Nodal restores oral-aboral patterning downstream from p38. The left column shows schematics representing the experiments for each panel. (A) SB-wash (SB W) treatment with a control 2-cell (2c) injection. (B) 2c Gsc injections without SB treatment. (C) 2c Gsc injections with SB-wash treatment. (D) 2c Nod injections with SB-wash treatment. Brightfield or DIC (1), skeletal (2) and fluorescence (3) images are shown.
