Cre/lox系统广泛用于小鼠以实现细胞类型特异性基因表达。然而,一个强大的和普遍的反应系统,表达基因的Cre控制下仍然缺乏。我们已经产生了一组Cre报告小鼠与强大的,无处不在的不同光谱的荧光蛋白的表达。这些报告基因的强大天然荧光能够直接观察标记神经元的精细树突结构和轴突投射,这在绘制神经元回路、成像和跟踪体内特定细胞群中是有用的。使用这些报告和高通量原位杂交平台,我们正在系统地分析Cre指导的基因表达在整个小鼠大脑中的一些Cre驱动线,包括新的Cre线靶向不同的细胞类型在皮层。我们的表达数据显示在一个公共在线数据库中,以帮助研究人员评估各种Cre-driver系用于细胞类型特异性遗传操作的效用。
The Cre/lox system is widely used in mice to achieve cell-type-specific gene expression. However, a strong and universal responding system to express genes under Cre control is still lacking. We have generated a set of Cre reporter mice with strong, ubiquitous expression of fluorescent proteins of different spectra. The robust native fluorescence of these reporters enables direct visualization of fine dendritic structures and axonal projections of the labeled neurons, which is useful in mapping neuronal circuitry, imaging and tracking specific cell populations in vivo. Using these reporters and a high-throughput in situ hybridization platform, we are systematically profiling Cre-directed gene expression throughout the mouse brain in a number of Cre-driver lines, including novel Cre lines targeting different cell types in the cortex. Our expression data are displayed in a public online database to help researchers assess the utility of various Cre-driver lines for cell-type-specific genetic manipulation.
