(Submitter supplied) The first site exhibiting hematopoietic activity in mammalian development is the yolk sac blood island, which originates from the hemangioblast. Here we performed differentiation assays, as well as genome-wide molecular and functional studies in BL-CFCs to gain insight into the function of the essential Ldb1 factor in early primitive hematopoietic development. We show that the previously reported lack of yolk sac hematopoiesis and vascular development in Ldb1-/- mouse result from a decreased number of hemangioblasts and a block in their ability to differentiate into erythroid and endothelial progenitor cells. more...

(Submitter supplied) Human embryonic stem cells (hESCs) are a powerful tool for modeling regenerative therapy. To search for the genes that promote hematopoietic development from human pluripotent stem cell, we overexpressed a list of hematopoietic regulator genes in human pluripotent stem cell-derived CD34+CD43- endothelial cells (ECs) enriched in hemogenic endothelium. Among genes tested, only SOX17, a gene encoding a transcription factor of the SOX family, promoted cell growth and supported expansion of CD34+CD43+CD45-/low cells expressing a hemogenic endothelial maker VE-cadherin. more...

(Submitter supplied) The differentiation of human embryonic stem cells to hematopoietic lineages initiates with the specification of hemogenic endothelium, a transient specialized endothelial precursor of all blood cells.Unfortunately, absence of hemogenic endothelium-specific markers as well as lack of consensus in the timing of hemogenic potential analysis and methodologies used to study the hematopoietic potential of this precursor prevents reaching clear and definite conclusions. more...

(Submitter supplied) Identification of the regulators that lead to arterial specification with definitive hematopoietic potential should help to design strategies to recapitulate HSC development from human pluripotent stem cells (hPSCs). Here, using ETS1 conditional H1 hESC line, we found that ETS1 induction at the mesodermal stage of differentiation dramatically enhances the arterial specification in hPSC cultures and formation of DLL4+CXCR4+/- arterial HE with lymphoid potential and the capacity to produce red blood cells with high expression of BCL11a and b-globin. more...

(Submitter supplied) Recently, we identified and characterized specific endothelial progenitors with varying hemogenic potential during human pluripotent stem cell differentiation. Based on these studies we established a platform on which we can manipulate NOTCH signaling on these subsets to elucidate the specific role of this signaling pathway during hemogenic endothelial specification, endothelial-to-hematopoietic transition, and definitive hematopoietic specification.

(Submitter supplied) Molecular mechanisms that regulate the generation of hematopoietic and endothelial cells from mesoderm are poorly understood. To define the underlying mechanisms, we compared gene expression profiles between embryonic stem (ES) cell-derived hemangioblasts (Blast-Colony-Forming Cells, BL-CFCs) and their differentiated progeny, Blast cells. Bioinformatic analysis indicated that BL-CFCs resembled other stem cell populations. more...

(Submitter supplied) The Recombination Activation Gene, RAG1, expression of which presages T-cell receptor gene rearrangement, is a key marker of T-cell commitment. Using RAG1:GFP human pluripotent stem cell reporter lines, we examined human T-cells genesis in the context of haemtopoietic organoids. We show that T-cell commitment occurs concomitantly with the emergence of blood cells from AGM-like haemogenic endothelium, predating the surface expression of CD5 and CD7. more...

(Submitter supplied) In hESCs, expression of the Notch ligand DLL4 parallels the emergence of bipotent hematoendothelial progenitors (HEPs) and promotes their hematopoietic differentiation. During differentiation, DLL4 is only expressed in a subpopulation of HEPs. To study the developmental fate of the two subpopulations of HEPs identified by DLL4 expression, we FACS-isolated DLL4high and DLL4low/- HEPs at day 15 of differentiation and performed gene expression analysis using microarrays
