In mice, only the zygotes and blastomeres from 2-cell embryos are authentic totipotent stem cells (TotiSCs), capable of producing all the differentiated cells in both embryonic and extraembryonic tissues and forming an entire organism1. However, it remains challenging whether and how TotiSCs, representing the very beginning of a life, can be established in vitro in the absence of germline cells. Here, we demonstrate induction and long-term maintenance of TotiSCs from mouse pluripotent stem cells
