SOX2 and fetal growth restriction: We then explored the effects on embryonic DG neurogenesis by systematically quantifying the percentages of Sox2+ neural stem cells (NSCs) that give rise Tbr2+ intermediate neuronal progenitors (INPs), NeuroD+ NPs, and Prox1+ immature and mature glutamatergic granule neurons (Seki et al., 2014) during early and late IUGR.
