Application of a novel population of multipotent stem cells derived from skin fibroblasts as donor cells in bovine SCNT.

ABSTRACT: Undifferentiated stem cells are better donor cells for somatic cell nuclear transfer (SCNT), resulting in more offspring than more differentiated cells. While various stem cell populations have been confirmed to exist in the skin, progress has been restricted due to the lack of a suitable marker for their prospective isolation. To address this fundamental issue, a marker is required that could unambiguously prove the differentiation state of the donor cells. We therefore utilized magnetic activated cell sorting (MACS) to separate a homogeneous population of small SSEA-4(+) cells from a heterogeneous population of bovine embryonic skin fibroblasts (BEF). SSEA-4(+) cells were 8-10 μm in diameter and positive for alkaline phosphatase (AP). The percentage of SSEA-4(+) cells within the cultured
