Derivation of totipotent-like stem cells with blastocyst-like structure forming potential
文献摘要：
It is challenging to derive totipotent stem cells in vitro that functionally and molecularly resemble cells from totipotent embryos.Here,we report that a chemical cocktail enables the derivation of totipotent-like stem cells,designated as totipotent potential stem(TPS)cells,from 2-cell mouse embryos and extended pluripotent stem cells,and that these TPS cells can be stably maintained long term in vitro.TPS cells shared features with 2-cell mouse embryos in terms of totipotency markers,transcriptome,chromatin accessibility and DNA methylation patterns.In vivo chimera formation assays show that these cells have embryonic and extraembryonic developmental potentials at the single-cell level.Moreover,TPS cells can be induced into blastocyst-like structures resembling preimplantation mouse blastocysts.Mechanistically,inhibition of HDAC1/2 and DOT1L activity and activation of RARγ signaling are important for inducing and maintaining totipotent features of TPS cells.Our study opens up a new path toward fully capturing totipotent stem cells in vitro.
