Interactions between inductive tissues can suppress as well as activate. The early organizer cells express Goosecoid, a transcription factor that activates genes encoding soluble signals. These cells come into contact with new groups of cells that produce various growth factors as they move forward in the blastocoel. For any body structure to form, particular growth factors need to be suppressed.
