Medial hinge point (MHP) cells are present both in the spinal and the cranial neural plate.
The transition of neural plate cells to MHP cells is not a differentiation process, but rather a comprehensive change in morphology, with reduced apical (apical constriction) and increased basal cell diameters. This new morphology drives a process of neural plate bending at the ventral midline and elevation of the neural folds.
Bending of the neural plate to form the neural tube occurs at two principle sites: the MHP, that overlies the notochord, and the dorsolateral hinge points (DLHPs) that are situated at the connection of the neural plate with the remainder of the ectoderm.
