利用最近确定的Sox10远端增强子指导Cre表达,我们报告S4F:Cre,能够诱导重组的少突胶质细胞和所有检查的神经嵴衍生组织的转基因小鼠系。使用R26 R:LacZ报告基因小鼠测定,在神经嵴衍生的组织中检测到表达,所述神经嵴衍生的组织包括形成面部骨骼、背根神经节、交感神经节、肠神经系统、脊椎和成黑素细胞,与Sox 10表达一致。LacZ报告基因表达也检测到非神经嵴衍生的组织,包括少突胶质细胞和腹侧神经管。该品系在Cre表达模式上与标记神经嵴群体的其他转基因小鼠品系(包括由其他SoxE蛋白的表达定义的其他群体)存在明显差异。因此,S4 F:Cre转基因系将成为这些群体谱系追踪、基因功能表征和基因组操作的强大工具。
Utilizing a recently identified Sox10 distal enhancer directing Cre expression, we report S4F:Cre, a transgenic mouse line capable of inducing recombination in oligodendroglia and all examined neural crest derived tissues. Assayed using R26R:LacZ reporter mice expression was detected in neural crest derived tissues including the forming facial skeleton, dorsal root ganglia, sympathetic ganglia, enteric nervous system, aortae and melanoblasts, consistent with Sox10 expression. LacZ reporter expression was also detected in non-neural crest derived tissues including the oligodendrocytes and the ventral neural tube. This line provides appreciable differences in Cre expression pattern from other transgenic mouse lines that mark neural crest populations, including additional populations defined by the expression of other SoxE proteins. The S4F:Cre transgenic line will thus serve as a powerful tool for lineage tracing, gene function characterization and genome manipulation in these populations.
