Abstract: There is described herein a method of enriching a population of stem cells for hematopoietic progenitors. The method comprises inducing hematopoietic differentiation in a population of human embryonic stem cells or human induced pluripotent stem cells; sorting the population based on expression of CD43 and at least one of CD34, CD31 and CD144; and selecting a fraction that is at least one of CD34*CD43-, CD31*CD43- and CD144*CD43-. Also provided are populations of hematopoietic progenitors obtained by the methods described herein.

Abstract: Provided are methods and products for obtaining cardiovascular lineage cells from hPSCs. The method for obtaining a cardiomyocyte lineage or an epicardial lineage cell population from human pluripotent stem cells (hPSCs) comprises one or more of the following steps: (a) contacting BMP component primed hPSCs with a cardiovascular mesoderm programming cocktail suitable for inducing the hPSCs to differentiate to a cardiovascular mesoderm cell population under conditions suitable for the programming cocktail to penetrate the hPSCs and culturing the contacted hPSCs for a period of time to generate a KDR+ and PDGFRalpha+ cardiovascular mesoderm cell population; (b) contacting the cardiovascular mesoderm cell population with a cardiovascular progenitor specification cocktail suitable to specify a NKX2-5+ or WT1+ cardiovascular progenitor cell population under conditions suitable for the specification cocktail to penetrate the cardiovascular mesoderm cell population and culturing the contacted cardiovascular mesoderm cell population for a period of time to generate a NKX2-5+ or WT1+ cardiovascular progenitor cell population; and (d) contacting the cardiovascular progenitor cell population with a maturation cocktail under conditions suitable for the maturation cocktail to penetrate the cardiovascular progenitor cell population and culturing the contacted cardiovascular progenitor population for a period of time to produce a cardiovascular population optionally cardiomyocyte lineage cells expressing cardiac troponin T (cTnT) and/or SIRPA and/or epicardial lineage cells expressing WT1.

Abstract: Methods for producing hepatocyte and/or cholangiocyte lineage cells from pluripotent stem cells, the method comprising (a) specifying the extended nodal agonist treated induced endodermal cell population to obtain a cell population comprising hepatocyte and/or cholangiocyte progenitors by contacting the extended nodal agonist treated induced endodermal cell population with specification media comprising a FGF agonist and a BMP4 agonist and/or active conjugates and/or fragments thereof; (b) inducing maturation, and optionally further lineage specification and/or expansion of the hepatocyte and/or cholangiocyte progenitors of the cell population to obtain a population comprising hepatocyte lineage cells such as hepatoblasts, hepatocytes and/or cholangiocytes, the inducing maturation step comprising generating aggregates of the cell population. Optionally, the method also comprises activating the cAMP pathway within the aggregates and forming co-aggregates.
