Chimeric analysis of T (Brachyury) gene function.


To investigate T(Brachyury) gene function, a chimeric analysis of midgestation (9.5-11.5 days post coitum) embryos has been performed. Embryonic stem (ES) cell lines homozygous or heterozygous for the T gene have been introduced into wild-type host embryos by blastocyst injection, and the resulting chimeras scored for morphological abnormality and extent of… (More)
