Abstract
Compositions and methods are provided for depletion of pluripotent cells. In one embodiment of the invention, methods are provided for depletion of pluripotent cells from a mixed population of differentiated cells and stem cells, to provide a population of cells substantially free of pluripotent stem cells. Monoclonal antibodies useful in depletion and in identification of pluripotent stem cells are also provided.
Claims8
A method of depleting teratoma-forming pluripotent stem cells from a mixed cell population comprising cells differentiated from the pluripotent stem cells, the method comprising:
- contacting a mixed population of cells suspected of comprising pluripotent stem cells with an antibody that specifically binds an H type-1 antigen epitope recognized by monoclonal antibody 8e11;
- and
- depleting from said population those cells that bind to the antibody, to provide a differentiated cell population depleted of teratoma-forming pluripotent stem cells.
