Abstract

Previous work demonstrating the existence of intermediate pluripotency states in post-implantation embryos had ignited a debate on whether "formative" pluripotency can be stabilized in pluripotent stem cell (PSC) lines. In this issue of Cell Stem Cell, two papers show that polarized epithelial and germ cell-competent formative PSCs can be maintained in modified activin-dependent conditions.
