  • Patent number: 9822336
    Abstract: A method for making an at least double layered cell aggregate and/or an artificial blastocyst, and/or a further-developed blastoid termed blastoid, by forming a double layered cell aggregate from at least one trophoblast cell and at least one pluripotent and/or totipotent cell, and culturing the aggregate to obtain an artificial blastocyst having a trophectoderm-like tissue that surrounds a blastocoel and an inner cell mass-like tissue. The cell aggregate can be formed from toti- or pluripotent stem cell types, or induced pluripotent stem cell types, in combination with trophoblast stem cells. Formation of a blastoid can be achieved by culturing the cell aggregate in a medium preferably comprising one or more of a Rho/ROCK inhibitor, a Wnt pathway modulator, a PKA pathway modulator, a PKC pathway modulator, a MAPK pathway modulator, a STAT pathway modulator, an Akt pathway modulator, a Tgf pathway modulator and a Hippo pathway modulator.

  • Publication number: 20140193913
    Abstract: The methods and compositions described herein are based, in part, on the discovery of a stem cell state in human cells that resembles the morphology observed in murine-derived stem cells. Induction of such a state in human stem cells permits an increase in the efficiency of homologous recombination. Thus, the methods and compositions described herein relate to cells and methods for increasing the efficiency of homologous recombination in human stem cells.
