Therefore, TLSCs represent a highly valuable cell type for studies of totipotency and embryology.ĢC-like cells Dot1l Kdm5b MERVL blastoid broad H3K4me3 domains chromocenter pericentromeric heterochromatin totipotency.Ĭopyright © 2022 Elsevier Inc. Functionally, TLSCs are competent for germline transmission and give rise to both embryonic and extraembryonic lineages at high frequency. These totipotent-like stem cells (TLSCs) are stable in culture and possess unique molecular features of the mouse 2C embryo. Our protocol establishes a closer match of mouse 2-cell (2C) embryos than any other 2C-like cells. In the case of humans, the gametes sperm and egg, fuse to form a zygote. Our approach of remodeling the pericentromeric heterochromatin and re-establishing the totipotency-specific broad H3K4me3 domains promotes the pluri-to-totipotency transition. Totipotent stem cells are embryonic stem cells characterized by their ability to generate all portions of a product of conception including the embryo and extraembryonic tissues such as placental tissues and fetal membranes. Stable totipotent cell cultures and deciphering the principles of totipotency regulation would be invaluable to understand cell plasticity and lineage segregation in early development. Potency is also described as the gene activation potential within a cell, which like a continuum, begins with totipotency to designate a cell with the most differentiation potential, pluripotency, multipotency, oligopotency, and finally unipotency. The more cell types a cell can differentiate into, the greater its potency. Totipotent cells have more robust developmental potency than any other cell types, giving rise to both embryonic and extraembryonic tissues. Cell potency is a cell's ability to differentiate into other cell types.
