title: Wnt7a overexpression delays beta-tubulin III expression in transgenic mouse embryos.
abstract: Wnt7a and HA-tagged Wnt7a have previously been shown to promote or delay neuronal differentiation respectively. In this study, we show that embryonic days 9.5 and 10.5 transgenic mouse embryos overexpressing Wnt7a specifically in nestin-positive neural stem/progenitor cells displayed a delay in neuronal differentiation, assayed by beta-tubulin III expression. Our results corroborate previous studies using HA-Wnt7a, and suggest a critical role for Wnt7a in control of neuronal progenitor maturation.
