来自胚胎干(ES)细胞的转基因小鼠品系已成为功能基因组学和生物医学研究的重要工具。大规模诱变项目正在产生突变型 C57BL/6 (B6) ES 细胞文库,以便对小鼠基因组的每个基因进行功能注释。为了实现这些资源的利用,需要有效且易于使用的方法从这些 ES 细胞中产生突变小鼠。在这里,我们描述了 ICR 桑椹胚聚集体和化学成分确定的培养基的组合,该培养基具有广泛可用和易获得的成分,用于从 C57BL/6N ES 细胞高效产生种系传递嵌合体。这些方法共同将使更广泛的生物医学研究界更容易获得公开的 B6 ES 细胞资源。
Genetically modified mouse strains derived from embryonic stem (ES) cells have become essential tools for functional genomics and biomedical research. Large scale mutagenesis projects are producing libraries of mutant C57BL/6 (B6) ES cells to enable the functional annotation of every gene of the mouse genome. To realize the utility of these resources, efficient and accessible methods of generating mutant mice from these ES cells are necessary. Here, we describe a combination of ICR morula aggregation and a chemically-defined culture medium with widely available and accessible components for the high efficiency generation of germline transmitting chimeras from C57BL/6N ES cells. Together these methods will ease the access of the broader biomedical research community to the publicly available B6 ES cell resources.
