摘要：

A full description of the ontogeny of the p cell would guide efforts to generate P cells from embryonic stem cells (ESCs). The first step requires an understanding of definitive endoderm: the genes and signals responsible, for its specification, proliferation, and patterning. This report describes a global marker of definitive endoderm, Claudin-6 (Cldn6). We report its expression in early development with particular attention to definitive endoderm derivatives. To create a genetic system to drive gene expression throughout the definitive endoderm with both spatial and temporal control, we target the endogenous locus with an inducible Cre recombinase (Cre-ERT2) Cassette. Cldn6 null mice are viable and fertile with no obvious phenotypic. abnormalities. We also report a lineage analysis of the fate of Cldn6-expressing embryonic cells, which is relevant to the development of the pancreas, lung, and liver.
