Abstract

Disclosed herein are human trophoblast stem (hTS) cells, differentiated cells thereof, derivatives thereof such as cellular mass, and uses thereof. The isolation of hTS cells can express FGF4, FGFR-2, Oct4, Thy-1, and stage-specific embryonic antigens distributed in different compartments of the cell. The hTS cells are able to derive into specific cell phenotypes of the three primitive embryonic layers, produce chimeric reactions in mice, and retain a normal karyotype and telomere length. In the hTS cells, Oct4 and fgfr-2 expressions can be knockdown by bFGF. The hTS cells could apply to human cell differentiation and for gene and cell-based therapies.
