Wnt信号在调节皮质和海马发育中起着重要作用,但许多其他的背侧端脑发育的分子机制在很大程度上是未知的。我们正在利用Wnt信号通路的信号成分的高度区域化表达模式来产生新的小鼠品系,这将有助于研究前脑发育。在这里,我们描述了一个转基因小鼠线,其中Cre是由Wnt受体,Frizzled10的启动子驱动。在这些小鼠中,Cre活性主要在发育期间的端脑背侧检测到,并且仅限于成年海马中的锥体细胞场。当通过将转基因系与ROSA 26报告系杂交来测定时,Cre重组酶具有非常高的效率。因此,这Cre线将是有用的研究背端脑的发展和条件失活的靶基因在皮层和海马。
Wnt signaling plays an important role in regulating cortical and hippocampal development, but many of the other molecular mechanisms underlying dorsal telencephalic development are largely unknown. We are taking advantage of the highly regionalized expression patterns of signaling components of the Wnt pathway to generate new mouse lines that will be useful for studying forebrain development. Here, we describe a transgenic mouse line where Cre is driven by the promoter of the Wnt receptor, Frizzled10. In these mice, Cre activity is mainly detected in the dorsal telencephalon during development and is confined to the pyramidal cell fields in the adult hippocampus. The Cre recombinase has very high efficiency when assayed by crossing the transgenic line with the ROSA26 reporter line. Thus, this Cre line will be useful for the study of dorsal telencephalic development and conditional inactivation of target genes in the cortex and hippocampus.
