Evidence Mounts Against Mainstream Dogma In Embryology, Could Shed New Light On Neurological Defects

Summary:
New work on zebrafish development is about to complicate a debate already brewing among embryologists. According to the mainstream dogma, the notochord, a rod-like structure that precedes the vertebral column in vertebrate embryos, signals neural cells to induce the formation of floor plate, a crucial row of cells that lies along the floor of the ventral brain and spinal cord. This belief has come under fire recently, as new data about floor plate development cast doubt on the authoritative role of the notochord.
