WebAug 17, 2024 · However, in FGF9/16/20 knockdown embryos, notochord fate recovers during later development. It is thus not clear if FGF signalling is an essential requirement for notochord specification in Ciona embryos. We show that FGF-MEK-ERK signals act during two distinct phases to establish notochord fate. During the first phase, FGF signalling is ...
