(Submitter supplied) GATA2 is essential for the endothelial-to-hematopoietic transition (EHT) and generation of hematopoietic stem cells (HSCs). It is poorly understood how GATA2 controls the development of human pluripotent stem cell (hPSC)-derived HSC-like cells. Here, using human embryonic stem cells (hESCs) in which GATA2 overexpression was induced by doxycycline (Dox), we elucidated the dual functions of GATA2 in definitive hematopoiesis before and after the emergence of CD34+CD45+CD90+CD38- HSC-like cells. more...

(Submitter supplied) The Gata2 transcription factor is a pivotal regulator of hematopoietic stem cell (HSC) development and maintenance. Gata2 functions in the embryo during endothelial cell to hematopoietic cell transition (EHT) to affect hematopoietic cluster, HPC and HSC formation. Although previous studies of cell populations phenotypically enriched in HPCs and HSCs show expression of Gata2, there has been no direct study of Gata2 expressing cells during normal hematopoiesis. more...

(Submitter supplied) We generated GATA2/eGFP knockin human embryonic stem cells (H1-GATA2W/eGFP hESCs) and analyzed eGFP expression at different hematopoietic stages, paritcularly the hemogenic endothelium (HE) and hematopoietic progenitor cell (HPC) stage. Our results revealed that, at the HE stage, eGFP expression discriminates authentic HE from non-hematopoietic endothlial cells (EC) and, at the HPC stage, eGFP expression marks the HPC. more...

(Submitter supplied) In vertebrates, GATA2 is a master regulator of hematopoiesis and is expressed throughout embryo development and in adult life. Although the essential role of GATA2 for the onset of mouse hematopoiesis is well established, its involvement during early human hematopoietic development is not clear. By combining time-controlled overexpression of GATA2 with genetic knockout experiments, we found that GATA2, at the mesoderm specification stage, promotes the generation of hemogenic progenitors and their further differentiation to hematopoietic progenitor cells, while negatively regulating cardiac differentiation. more...

(Submitter supplied) Hematopoietic differentiation from human pluripotent stem cell in vitro is an important approach for the research of hematopoietic stem cell regeneration. Small molecules that can maintenance low ROS level and inhibit cell apoptosis or autophagy are benifit for the maintenance or expansion of hematopoietic stem cells. Lipoic acid (ALA) as a small antioxidant molecule can regulate the ROS level and apoptosis of cells. more...

(Submitter supplied) We generated homozygous GATA2 knockout human embryonic stem cells (GATA2-/- hESCs) and analyzed their blood differentiation potential. Paritcularly at the hemogenic endothelium (HE) stage and hematopoietic progenitor cell (HPC) stage. Our result revealed that GATA2-/- hESCs displayed attenuated generation of CD34+CD43+ HPCs, due to the impairment of endothelial to hematopoietic transition (EHT). However, GATA2-/- hESCs retained the potential to generate erythroblasts, macrophages, but never granulocytes. 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) During development, hematopoietic stem/progenitor cells (HSPCs) arise from specialized endothelial cells by a process termed endothelial-to-hematopoietic transition (EHT). The genetic program driving human HSPC emergence remains largely unknown. We previously reported that the generation of hemogenic precursor cells from mouse fibroblasts recapitulates developmental hematopoiesis. Here, we demonstrate that human fibroblasts can be reprogrammed into hemogenic cells by the same transcription factors. more...
