Most importantly, analysis of brain sections derived from Nestin-Cre conditional mouse models revealed the presence of hydrocephalus with dilation of the third ventricle at day P8 (Figure 6C–H, n = 2), which was subsequently followed by the dilation of the lateral ventricles, showing a mild but typical triventricular phenotype by day P10 (Figure 6I–J, n = 3). This evidence concerns the gene NES and Hydrocephalus.
