摘要
Abstract Many attempts have been made to induce high-quality embryonic stem cells such as pluripotent stem cells and totipotent stem cells, but challenges remain to be overcome such as appropriate methods and sources. Demethylation of the genome after fertilization is an important step to initiate zygote gene activation, which can lead to the development of new embryos. Here, we tried to induce totipotent stem cells by mimicking DNA demethylation patterns of the embryo. Our data showed, after induction of DNA demethylation via chemicals or knockdown of Dnmts, cells positive for Nanog, and Cdx2 emerged. These cells could differentiate into the pluripotent and trophoblast lineage cells in-vitro. After transferring these cells to the uterus, they can implant and form embryo-like structures. Our study showed the importance of DNA demethylation roles in totipotent stem cell induction and a new and easy way to induce this cell type.
