Two distinct trophectoderm lineage stem cells from human pluripotent stem cells.

ABSTRACT: The trophectoderm layer of the blastocyst-stage embryo is the precursor for all trophoblast cells in the placenta. Human trophoblast stem (TS) cells have emerged as an attractive tool for studies on early trophoblast development. However, the use of TS cell models is constrained by the limited genetic diversity of existing TS cell lines and restrictions on using human fetal tissue or embryos needed to generate additional lines. Here we report the derivation of two distinct stem cell types of the trophectoderm lineage from human pluripotent stem cells. Analogous to villous cytotrophoblasts in vivo, the first is a CDX2^- stem cell comparable with placenta-derived TS cells-they both exhibit identical expression of key markers, are maintained in culture and differentiate under simila
