(PhysOrg. com) -- Normal vertebrate brain ventricle formation relies upon the stretchiness or "relaxation" of the neuroepithelium, which is regulated by the motor protein myosin.
"The neuroepithelium is really complicated," says Gutzman, who relied on sophisticated imaging and three-dimensional reconstruction techniques to observe brain individual cells in the living embryo.
Gutzman and Sive conclude that the neuroepithelium must relax, through reduction of myosin activity, for the hindbrain ventricle to reach its normal working volume.
The squatter shape of the cells offered a clue as to why the neuroepithelium might be less flexible.

NesCre is expressed in neuroepithelium by neuronal and glial precursors.
The aggregates were of a uniform size and, remarkably, more than 95\% of the cells within them formed a consistent curved sheet during the first 5 days in culture, which closely resembled the neuroepithelium that forms on the outer surface of the embryo during the earlier stages of neural development.
