Abstract Human embryonic stem cells provide a unique tool to study early events occurring in the development of human embryonic hematopoiesis, and their totipotent capability indicates a potent clinical application based on the cellular therapy and the evaluation of drug effects on hematopoietic and blood cells. To achieve efficient production of hematopoietic cells from human embryonic stem cells, we attempted to reproduce the circumstance surrounding embryonic hematopoietic cells in vitro. Since fetal liver is the predominant source of hematopoietic and blood cells in mammalian embryogenesis, we established stromal cells from mouse fetal liver at days 14 to 15 of gestation. In the co-culture of human embryonic stem cells with the established stromal cells, a number of hematopoietic progenitors were generated at around day 14 of co-culture, and this hematopoietic activity was highly enriched in the cobble stone-like cells under the stromal layer. Most of the cobble stone-like cells collected expressed CD34 and contained a variety of hematopoietic colony-forming cells, especially multilineage colony-forming cells, at a high frequency. The multipotential hematopoietic progenitors in the cobble stone-like cells produced all types of mature blood cells, including adult type hemoglobin-synthesizing erythrocytes and tryptase and chymase-bouble positive mast cells in the suspension cultiue with a cytokine cocktail. The developed co-culture system of human embryonic stem cells should offer a novel source for hematopoietic and blood cells applicable to cellular therapies and drug screening.

Abstract Induced pluripotent stem cells (iPSCs) provide an unprecedented opportunity for modeling of human diseases in vitro as well as for developing novel approaches for regenerative therapy based on immunologically compatible cells. In the present study, we employed an OP9 differentiation system to characterize the hematopoietic differentiation potential of seven human iPSC lines obtained from human fetal, neonatal, and adult fibroblasts through reprogramming with POU5F1, SOX2, NANOG, and LIN28 and compared it with the differentiation potential of five human embryonic stem cell lines (hESC; H1, H7, H9, H13, and H14). Similar to hESCs, all iPSCs in coculture with OP9 generated all types of colony forming cells (CFCs) as well as CD34+ cells that can be separated into distinct subsets based on differential expression of CD43 and CD31. CD34+CD31+CD43− cells obtained from all iPSCs expressed molecules present on endothelial cells and readily formed a monolayer when placed in endothelial conditions, while hematopoietic CFC potential was restricted to CD43+ cells. iPSC-derived CD43+ cells could be separated into three major subsets based on differential expression of CD235a/CD41a and CD45: CD235a+CD41a+/− (erythro-megakaryocytic progenitors), and lin-CD34+CD43+CD45− (multipotent), and lin-CD34+CD43+CD45+ (myeloid-skewed) primitive hematopoietic cells. Both subsets of primitive hematopoietic cells expressed genes associated with myeloid and lymphoid development, although myeloid genes were upregulated in CD45+ cells, which are skewed toward myeloid differentiation. Cytogenetic analysis demonstrated that iPSCs and derived from them CD43+ cells maintained normal karyotype. In addition short tandem repeat analysis of CFCs generated from IMR90-1 cells has been performed to confirm that blood cells are in fact derived from reprogrammed IMR90 cells, and not from contaminating hESCs. While we observed some variations in the efficiency of hematopoietic differentiation between different iPSCs, the pattern of differentiation was very similar in all seven tested iPSC and five hESC lines. Using different cytokine combinations and culture conditions we were able to expand iPSC-derived myeloid progenitors and induce their differentiation toward red blood cells, neutrophils, eosinophils, macrophages, ostoeclasts, dendritic and Langerhans cells. Although several issues remain to be resolved before iPSC-derived blood cells can be administered to humans for therapeutic purposes, patient-specific iPSCs can already be used for characterization of mechanisms of blood diseases and to identify molecules that can correct affected genetic networks.

Background. In vitro methods for hematopoietic differentiation of human pluripotent stem cells (hPSC) are a matter of priority for the in-depth research into the mechanisms of early embryogenesis. So-far, published results regarding the generation of hematopoietic cells come from studies using either 2D or 3D culture formats, hence, it is difficult to discern their particular contribution to the development of the concept of a unique in vitro model in close resemblance to in vivo hematopoiesis. Aim of the study. To assess using the same culture conditions and the same time course, the potential of each of these two formats to support differentiation of human pluripotent stem cells to primitive hematopoiesis without exogenous activation of Wnt signaling. Methods. We used in parallel 2D and 3D formats, the same culture environment and assay methods (flow cytometry, IF, qPCR) to investigate stages of commitment and specification of mesodermal, and hemogenic endothelial cells to CD34 hematopoietic cells and evaluated their clonogenic capacity in a CFU system. Results. We show an adequate formation of mesoderm, an efficient commitment to hemogenic endothelium, a higher number of CD34 hematopoietic cells, and colony-forming capacity potential only in the 3D format-supported differentiation. Conclusions. This study shows that the 3D but not the 2D format ensures the induction and realization by endogenous mechanisms of human pluripotent stem cells’ intrinsic differentiation program to primitive hematopoietic cells. We propose that the 3D format provides an adequate level of upregulation of the endogenous Wnt/β-catenin signaling.
