The present invention relates to novel pluripotent embryonic cell populations derived from embryonic stem cell populations and methods to produce such pluripotent embryonic cell populations. Disclosed is an embryonic stem cell-derived pluripotent embryoid body cell population having one or more cells capable of developing into cells of hematopoietic and/or endothelial lineage. Also disclosed is an embryoid body cell population-derived mixed population of endothelial and erythroid cells. Also disclosed is an embryoid body cell population-derived embryonic blast cell population capable of developing into a variety of hematopoietic cell types. The invention is additionally directed to embryonic stem cell population-derived T and B cell populations. Methods to identify embryonic cell compounds are also disclosed for therapeutic and experimental use.
A pluripotent cell population that is pluripotent for development into primitive erythroid cells, definitive erythroid cells, macrophages, neutrophils, mast cells, T cells, endothelial cells, B cells, natural killer cells megakaryocytes, eosinophils, and progenitors and progeny thereof, wherein said cell population is derived by culturing an embryonic stem cell population to obtain an embryoid body cell population, followed by culturing said embryoid body cell population under conditions effective to produce said pluripotent cell population, said conditions comprising an embryonic blast cell medium.
A pluripotent cell population that is pluripotent for development into primitive erythroid cells, definitive erythroid cells, macrophages, neutrophils, mast cells, T cells, endothelial cells, B cells, natural killer cells, megakaryocytes, eosinaphils, and progenitors and progeny thereof, wherein said pluripotent cell population is derived by:
A method for obtaining a pluripotent cell population that is pluripotent for development into primitive erythroid cells, definitive erythroid cells, macrophages, neutrophils, mast cells, T cells, endothelial cells, B cells, natural killer cells, megakaryocytes, eosinophils, and progenitors and progeny thereof, said method comprising culturing an embryonic stem cell population to obtain an embryoid body cell population, followed by culturing a population of embryoid body cells under conditions effective to obtain said pluripotent cell population, said conditions comprising an embryonic blast cell medium.
