Adult cells can only give rise to the same cell type. For example, a skin cell cannot give rise to a muscle cell but to skin cells only. This limits the potential use of adult cells for therapy.
Although the literature describes the mammalian zygote as a totipotent cell, one researcher challenges this view and has proposed a revised alternative model of mammalian cellular totipotency. The ...
Mouse embryonic stem cells (ESCs) have emerged as ideal tools for developmental biology research due to their characteristics such as unlimited proliferation and pluripotent differentiation potential.
Researchers discover L1td1 maintains stem cell pluripotency by degrading totipotency-associated RNAs
A new study has found that L1td1, a protein evolutionarily co-opted from the Long interspersed nuclear element 1 (LINE1) retrotransposon, functions as a critical "gatekeeper" restricting pluripotent ...
Mammalian eggs and sperm are highly specialized, differentiated cells, but when they fuse at fertilization the resulting zygote is able to give rise to an entire individual and its extraembryonic ...
Early mammalian development is a highly complex process involving elaborate and highly coordinated biological processes. One such process is zygotic genome activation (ZGA) which occurs following the ...

Scientists have found a way to induce totipotency in embryonic cells that have already matured into pluripotency. This has great potential to improve cell engineering capabilities for regenerative ...
Totipotency is the ability of a single cell to form an entire embryo, including extraembryonic tissues, an ability we have yet to recapitalize, in vitro. In a recent paper published in Science, Choi ...
Conditional genetics and single-embryo RNA-seq show that SETDB1 extinguishes the transient, retroelement-driven transcriptional programs of the totipotent two-cell state to facilitate the exit from ...
