Estimating the term…
The present invention relates to methods of modulating mammalian stem cell and progenitor cell differentiation. The methods of the invention can be employed to regulate and control the differentiation and maturation of mammalian, particularly human stem cells along specific cell and tissue lineages. The methods of the invention relate to the use of certain small organic molecules to modulate the differentiation of stem or progenitor cell populations along specific cell and tissue lineages, and in particular, to the differentiation of embryonic-like stem cells originating from a postpartum placenta or for the differentiation of early progenitor cells to a granulocytic lineage. Finally, the invention relates to the use of such differentiated stem or progenitor cells in transplantation and other medical treatments.

A method of treating an individual in need of granulocytes comprising administering a composition comprising a therapeutically effective amount of a compound to said individual, wherein the compound is 4-(amino)-2-(2,6-dioxo(3-piperidyl))-isoindoline-1,3-dione or 3-(4-amino-1-oxo-1,3-dihydro-isoindol-2-yl)-piperidine-2,6-dione, and wherein said compound, when contacted with mammalian CD34+ or CD133+ hematopoietic stem cells in vitro detectably increases the number of CFU-GM and detectably decreases the number of BFU-E differentiated from said stem cells relative to the numbers of CFU-GM and BFU-E differentiated from mammalian CD34+ or CD133+ hematopoietic stem cells not contacted with said compound.
