    Abstract: Methods for production of platelets from pluripotent stem cells, such as human embryonic stem cells (hESCs) and induced pluripotent stem cells (iPSCs) are provided. These methods may be performed without forming embryoid bodies or clusters of pluripotent stem cells, and may be performed without the use of stromal inducer cells. Additionally, the yield and/or purity can be greater than has been reported for prior methods of producing platelets from pluripotent stem cells. Also provided are compositions and pharmaceutical preparations comprising platelets, preferably produced from pluripotent stem cells.

    Abstract: The present invention relates to methods, kits and compositions for expansion of embryonic hematopoietic stem cells and providing hematopoietic function to human patients in need thereof. In one aspect, it relates to kits and compositions comprising a Notch agonist, one or more growth factors, and, optionally, an inhibitor of the TGFp pathway. Also provided herein are methods for expanding embryonic hematopoietic stem cells using kits and compositions comprising a Notch agonist, one or more growth factors, and, optionally, an inhibitor of the ΤΟΡβ pathway. The embryonic hematopoietic stem cells expanded using the disclosed kits, compositions and methods include cells derived from an embryo (e.g., aorta-gonad-mesonephros region of the embryo), embryonic stem cells, induced pluripotent stem cells, or reprogrammed cells of other types. The present invention also relates to administering the embryonic hematopoietic stem cells expanded using a combination of a Notch agonist, one or more growth factors, and, optionally, an inhibitor of the TGFp pathway to a patient for short-term and/or long-term in vivo repopulation benefits.
