  • Patent number: 11414649
    Abstract: The invention relates to a method for reprogramming cells from aged donors or senescent cells to pluripotent cells that have lost marks of senescence. In particular, the invention relates to an ex vivo method for preparing induced pluripotent stem cells (iPSCs) from a target cell population comprising cells from aged donors or senescent cells, said method comprising the steps of culturing said target cell population under appropriate conditions for reprogramming said cells into iPSCs, wherein said appropriate conditions comprises increasing expression in said target cells, of at least the following reprogramming factors: Oct4, Klf4, Sox2, c-Myc, Lin28 and, optionally Nanog.

  • Patent number: 8993330
    Abstract: A composition of a female germinal cell (egg) extract of pluricellular organisms in M-phase of the cell cycle, the extract being used for a mitotic remodeling of chromosomes of donor cells of pluricellular organisms, wherein the mitotic remodeling confers to the nucleus of the donor cells the ability to adapt themselves to the early embryonic development, in particular to the replication phases, in order to carry out the embryonic development or to obtain stem cells.
