Normal specification of the extraembryonic lineage after somatic nuclear transfer
24 Feb 2006
Abstract excerpt
To examine the establishment and maintenance of trophectoderm (TE) lineage in somatic cloned blastocysts, the expression of Cdx2, a key molecule for specification of TE fate, was immunohistochemically examined simultaneously with Oct4 expression. Cloned mouse embryos were made by nuclear transfer using cumulus cells, tail-tip fibroblasts, and embryonic stem cells. After 96 h of culture, the rates of...
