Methods are described to increase the proportion of endoderm committed cells and pancreatic lineage cells in a culture of human embryonic stem cells which are undergoing differentiation. The method also results in a stem cell derived cell culture which does not have tumorigenic capability.

Therapeutically programmed cells and methods for making such cells are provided. Therapeutically programmed cells are stem cells which have been matured such that they represent either a more differentiated state or a less differentiated state after contact with stimulatory factors. The therapeutically reprogrammed cells are suitable for cellular regenerative therapy and have the potential to differentiate into more committed cell lineages. Additionally, hybrid stem cells suitable for therapeutic reprogramming and cellular regenerative therapy are provided.

Disclosed herein are methods and compositions for treating cardiovascular disease and damaged cardiac tissue which employ at least one hyaluronan (HA) compound and one or more cells selected from the group consisting of stem cells, precursor cells, progenitor cells, committed cells, mature somatic cells, and recombinant cells.

A substantially enriched mammalian hematopoietic cell subpopulation is provided, which is characterized by progenitor cell activity for myeloid lineages, but lacking the potential to differentiate into lymphoid lineages. This population is further divided into specific myeloid progenitor subsets, including a common myeloid progenitor cells (CMP), megakaryocyte / erythroid progenitor cells (MEP) and granulocyte / monocyte lineage progenitor (GMP). Methods are provided for the isolation and culture of these subpopulations. The CMP population gives rise to all myeloid lineages, and can give rise to the two additional and isolatable progenitor populations that are exclusively committed to either the erythroid / megakaryocytic or myelomonocytic lineages. Tηεχελλενιχημεντμετηoδσεμπλoψεαγεντστηατσπεχαλλψεψoγνιζε Tηψ-1; ανδIΛ-7 Pα, in conjunction with other markers expressed on lineage committed cells. These cells give rise to a variety of myeloid cells, including megakaryocytes, granulocytes, dendritic cells and erythroid cells, as evidenced by their growth and differentiation in vitro and in vivo.

A substantially enriched mammalian hematopoietic cell subpopulation is provided, which is characterized by progenitor cell activity for lymphoid lineages, but lacking the potential to differentiate into myeloid and erythroid lineages. Methods are provided for the isolation and culture of this common lymphoid progenitor cell (CLP). The cell enrichment methods employ reagents that specifically recognize CDw127 (IL-7 receptor α); CD117 (c-kit) protein, in conjunction with other markers expressed on lineage committed cells. The murine cells are also characterized as expressing low levels of sca-1 (Ly-6E and Ly-6A). The CLPs are predominantly cycling, blast cells. These cells give rise to B cells, T cells and natural killer cells, as evidenced by their growth and differentiation in vitro and in vivo.

The first method to cause a culture of human and other primate stem cells to directly and uniformly differentiate into a committed cell lineage is disclosed. Treatment of primate stem cells with a single protein trophoblast induction factor causes the cells to transform into human trophoblast cells, the precursor cells of the placenta. Several protein factors including bone morphogenic protein 4 (BMP4), BMP2, BMP7, and growth and differentiation factor 5 can serve as trophoblast-inducting factors.

The present invention provides a method for selecting hematopoietic stem cells (HSCs) comprising providing an agent which binds to α9β1 integrin on the cell surface to a population of cells including HSCs and separating HSCs by virtue of the binding agent. The invention also provides a method of culturing a population of HSCs in the presence of an agent which binds to α9β1, wherein the agent inhibits differentiation of the HSCs. The invention also provides a method of producing a population of lineage committed cells comprising culturing HSCs in the presence of an agent which inhibits or prevents binding to α9β1.
