The reprogramming factors OCT4, SOX2, KLF4, and MYC (OSKM) can reactivate the pluripotency network in terminally differentiated cells, but also regulate expression of non-pluripotency genes in other contexts, such as the mouse primitive endoderm. The primitive endoderm is an extraembryonic lineage established in parallel to the pluripotent epiblast in the(More)
Trophoblast stem cells (TSCs) are derived from the early mouse embryo and can substantially contribute to placental development. Two studies by Kubaczka et al. (2015) and Benchetrit et al. (2015) in this issue of Cell Stem Cell now report reprogramming mouse fibroblasts into TSCs, surmounting the first lineage barrier established in development and(More)
Diverse pluripotent stem cell lines have been derived from the mouse, including embryonic stem cells (ESCs), induced pluripotent stem cells (iPSCs), embryonal carcinoma cells (ECCs), and epiblast stem cells (EpiSCs). While all are pluripotent, these cell lines differ in terms of developmental origins, morphology, gene expression, and signaling, indicating(More)
Transforming growth factor β (TGF-β) pathways are key determinants of cell fate in animals. Their basic mechanism of action is simple. However, to produce cell-specific responses, TGF-β pathways are heavily regulated by secondary factors, such as membrane-associated EGF-CFC family proteins. Cellular activities of EGF-CFC proteins have been described, but(More)
