A cross section of mouse cerebral cortex with progenitor cells labeled green and neurons in magenta. Duke researchers have identified the role of a gene called DDX3X in the formation of healthy ...

For counts of BrdU-labeled cells in postmitotic regions, matched cross-sections from anterior, middle and/or posterior cortex (350 μm across by width of cortex from pial to ventricular surface ...

The presence of Tuj1-, GABA- or calbindin-labeled neurons with their main processes oriented towards the ventricle in sections of fixed embryonic cortex lends support to these in vitro observations.
