NettetOur approach of remodeling the pericentromeric heterochromatin and re-establishing the totipotency-specific broad H3K4me3 domains promotes the pluri-to-totipotency transition. Our protocol establishes a closer match of mouse 2-cell (2C) embryos than any other 2C-like cells. Nettet1. jul. 2024 · Totipotency exists transiently in zygote and 2C embryo stages during early development, which subsequently commit to two distinct lineages; that is, the embryonic cell lineage (inner cell mass, ICM) that forms embryo proper and the extraembryonic cell lineage (trophectoderm, TE) that forms placental tissue (Figure 1 A).Embryonic stem …
