Mouse totipotent
Nettet14. mai 2024 · Since establishment of the first embryonic stem cells (ESCs), in vitro culture of totipotent cells functionally and molecularly comparable with in vivo blastomeres with embryonic and extraembryonic developmental potential has been a challenge. Here we report that spliceosomal repression in mouse ESCs drives a pluripotent-to-totipotent … NettetPosfai, Schell, Janiszewski et al. assess candidate totipotent stem cells with in vitro and in vivo assays of increasing stringency to evaluate their developmental potential and …

Nettet21. jun. 2024 · Totipotency refers to single cells’ developmental capacity to form an entire organism. Understanding how totipotent stem cells form has implications for chimera generation. In a recent Cell study, Shen et al. (2024) report that inhibition of spliceosomes resets conventional pluripotent stem cells to a cellular state with totipotency features. Nettet30. nov. 2024 · It is widely held that the first two blastomeres of mammalian embryos are equally totipotent and that this totipotency belongs to the group of regulative properties. However, this interpretation neglects an important aspect: evidence only came from successful monozygotic twins which can speak only for those pairs of half-embryos that …

Nettet6. apr. 2024 · Here, we show that the histone chaperone RBBP4, but not its homolog RBBP7, is indispensable for maintaining the identity of mouse embryonic stem cells (mESCs). Auxin-induced degradation of RBBP4, but not RBBP7, reprograms mESCs to the totipotent 2C-like cells. Also, loss of RBBP4 enhances transition from mESCs to …
