Chemical-induced chromatin remodeling reprograms mouse

WebOct 26, 2024 · 1 Introduction. The very first demonstration of totipotent cells in the embryo was from the works of Tarkowski, in which a single blastomere isolated from a 2-cell (2C) stage embryo was proven to be able to generate a whole adult mouse (Tarkowski, 1959).By definition, totipotency refers to the developmental potential of cells capable of … WebHere, 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 trophoblast cells. lambang pancasila ke 1-5
