Hematopoietic Development

Abstract Fanconi anemia (FA) is a genetically heterogeneous, autosomal recessive disorder characterized by pediatric bone marrow failure and congenital anomalies. The effect of FA gene deficiency on hematopoietic development in utero remains poorly described as mouse models of FA do not develop hematopoietic failure and such studies cannot be performed on patients. We have created a human-specific in vitro system to study early hematopoietic development in FA using a lentiviral RNA interference (RNAi) strategy in human embryonic stem cells (hESCs). We show that knockdown of FANCA and FANCD2 in hESCs leads to a reduction in hematopoietic fates and progenitor numbers that can be rescued by FA gene complementation. Our data indicate that hematopoiesis is impaired in FA from the earliest stages of development, suggesting that deficiencies in embryonic hematopoiesis may underlie the progression to bone marrow failure in FA. This work illustrates how hESCs can provide unique insights into human development and further our understanding of genetic disease.

Abstract To search for genes that promote hematopoietic development from human embryonic stem cells (hESCs) and induced pluripotent stem cells (iPSCs), we overexpressed several known hematopoietic regulator genes in hESC/iPSC-derived CD34+CD43− endothelial cells (ECs) enriched in hemogenic endothelium (HE). Among the 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 the HE marker VE-cadherin. SOX17 was expressed at high levels in CD34+CD43− ECs compared with low levels in CD34+CD43+CD45− pre-hematopoietic progenitor cells (pre-HPCs) and CD34+CD43+CD45+ HPCs. Sox17-overexpressing cells formed semiadherent cell aggregates and generated few hematopoietic progenies. However, they retained hemogenic potential and gave rise to hematopoietic progenies on inactivation of Sox17. Global gene-expression analyses revealed that the CD34+CD43+CD45−/low cells expanded on overexpression of Sox17 are HE-like cells developmentally placed between ECs and pre-HPCs. Sox17 overexpression also reprogrammed both pre-HPCs and HPCs into HE-like cells. Genome-wide mapping of Sox17-binding sites revealed that Sox17 activates the transcription of key regulator genes for vasculogenesis, hematopoiesis, and erythrocyte differentiation directly. Depletion of SOX17 in CD34+CD43− ECs severely compromised their hemogenic activity. These findings suggest that SOX17 plays a key role in priming hemogenic potential in ECs, thereby regulating hematopoietic development from hESCs/iPSCs.

Hematopoietic Development

Abstract To date, hematopoietic development of human embryonic stem cells (hESCs) has been limited to cell lines cultured in the presence of either mouse embryonic fibroblasts (MEFs) or MEF-conditioned media (MEF-CM). Anonymous xenogenic factors from MEFs or MEF-CM complicate studies of hESC self-renewal and also raise concerns for the potential clinical applications of generating primitive hematopoietic cells from hESC lines maintained under these ambiguous conditions. Here, we demonstrate that hESCs can be cultured over 30 passages in defined conditions in the absence of MEFs or MEF-CM using only serum replacement (SR) media and high concentrations of basic fibroblast growth factor (SR-bFGF). Similar to hESCs cultured in MEF-CM, hESCs cultured in SR-bFGF sustained characteristics of undifferentiated hESCs, proliferative potential, normal karyotype, in vitro and in vivo 3 germ-layer specification and gave rise to hemogenic-endothelial precursors required for subsequent primitive hematopoietic development. Our report demonstrates that anonymous factors produced by feeder cells are not necessary for hESC maintenance and subsequent hematopoietic specification, thereby providing a defined system for studies of hESC self-renewal and hESC-derived hematopoiesis.
