Research into the notochord has played a key role in understanding the development of the central nervous system. By transplanting and expressing a second notochord near the dorsal neural tube, 180 degrees opposite of the normal notochord location, one can induce the formation of motor neurons in the dorsal tube. Motor neuron formation generally occurs in the ventral neural tube, while the dorsal tube generally forms sensory cells. imperial cruiser cutaway illustrationimperial crystal 3 in 1 crystal game setWebIn vertebrates, the notochord develops from the axial mesoderm of the gastrula via inductive interactions involving the transforming growth factor β (TGFβ)-superfamily and fibroblast … imperial crystal wandWebFeb 2, 2024 · The proteins secreted by the notochord stimulate the formation of organ systems.
