ABSTRACT:
Novel regimens are provided for administering foreign genetically modified allogeneic cells to a host by combining the administration of the cells with a reduced regimen of an immunosuppressive agent. Particularly, cells having a reduced level of Class I MHC antigens may be employed in a variety of cellular therapy situations, where foreign cells are engrafted to treat diseased states.
