  • Differentiation of pluripotent embryonic stem cells
    Publication number: 20060223179
    Abstract: The invention relates to a method to induce primate embryonic stem cells to differentiate into a relatively homogenous population of mesoendoderm cells by treatment with caspase-like inhibitors. Also described is a population of mesoendoderm cells obtained therefrom. The embryonic stem cell derived mesoendoderm cells have the general morphological and cell surface marker characteristics of mesoendoderm cells.

  • Directed genetic modifications of human stem cells
    Publication number: 20060128018
    Abstract: Human embryonic stem cells can be genetically transformed by a combination of electroporation and homologous recombination. This technique makes it possible to create targeted inserts or deletions to the genome of the stem cells. This ability makes it possible to create populations of progeny cells which have differentiated into a target cell type of a specific desired lineage.
