Oxyq and PYZ treatment induced dorsalization in zebrafish. Morphology of zebrafish embryos treated with Oxyq and PYZ from 1K cells until early somitogenesis stage. The neural markers pax2a and krox20 showed lateral expansion (compare 4D to 4E and F). chd expression was expanded in treated groups over control (compare 4G to 4H and I). dusp6 expression showed mild expansion in OxyQ and PYZ treated groups over control.
