WebDec 2, 2024 · Some researchers have suggested that the notochord may secrete a protein called sonic hedgehog, which is involved in the development of the nervous system.

WebThe notochord secretes a protein called sonic hedgehog homolog (SHH), a key morphogen regulating organogenesis and having a critical role in signaling the development of motoneurons [3]. The secretion of SHH by the notochord establishes the ventral pole of the dorsal-ventral axis in the developing embryo.
