  <!g>Transgenic ES-like cells were injected into preimplantation embryos and
    transferred into surrogate mothersSix out of seven animals born were found onimeric for at least one tissue
    and overall onimerism was detected in derivatives from the three germ
    layers: actoderm, <!g>mesoderm and <!g>endodermIn <!g>bovine, embryonic <!g>pluripotent cells can be generated from somatic cells |

  Differentiation was induced by injection of cell into immuno-deficient
    miceTwo months after injection, teratomas were produced that included bone,
    muscle, gut, kidney neuronsFor transplantation therapies, a pure population of cells must be obtained |
