(Submitter supplied) HOXA7 regulates FL-HSPC self-renewal in vitro and in vivo. We profiled EB-HSPCs after HOXA7 overexpression (EB-HOXA7), or with a control vector (EB-CTR), to assess the gene expression programs regulated by HOXA7.

(Submitter supplied) The derivation of functional, transplantable HSCs from an pluripotent stem cells in vitro holds great promise for clinical therapies, but is unachieved. In order to achieve full functionality of HSCs, it is vital to determine the extent to which PSCs can currently be differentiated to the HSC program in vitro and identify the remaining dysregulated genetic pathways. Microarrays were used to compare the transcritomes of ESC-derived immunophenotypic HSPCs to endogenous HSPCs from various stages of development to determine the programs important for human HSC development and function, and which programs were lacking in ESC-derived hematopoietic cells.

(Submitter supplied) Gene expression profiling of primary cord blood hematopoietic stem cell (day 0, CD34+ cells), enriched control (untreated), Scriptaid and Valproic acid expanded CD34+ cells after a week in culture. Cord blood CD34+ cells were processed individually and equal number of PC and reisolated CD34+ cells from 3-4 samples were pooled after expansion to avoid sample variations.

(Submitter supplied) Human pluripotent stem cells were differentiated into hematopoietic progenitors, which were then re-specified using defined transcription factors to resemble hematopoietic stem cells (HSC) We used microarrays to establish the similarity between converted cells and purified human HSCs.

(Submitter supplied) During hematopoietic differentiation of hESCs, HOXA9 expression parallels hematopoietic development but is restricted to the hemogenic precursors (HEP, CD31+CD34+CD45-), and diminishes as HEPs differentiate into blood cells (CD45+). Enforced expression of Hoxa9 in hESCs robustly promoted differentiation into primitive (CD34+CD45+) and total (CD45+) blood cells with higher clonogenic (CFU) potential. more...

(Submitter supplied) Advances in pluripotent stem cell and reprogramming technologies have given hope of generating hematopoietic stem cells (HSC) in culture. To succeed, greater understanding of the self-renewing HSC during human development is required. We discovered that glycophosphatidylinositol-anchored surface protein GPI-80 (Vanin 2) defines a distinct subpopulation of human fetal hematopoietic stem/progenitor cells (HSPC) with self-renewal ability. more...

(Submitter supplied) One of the long-standing goals in the field has been to establish a culture system that would allow maintenance of HSC properties ex vivo. In the absence of such system, the ability to model human hematopoiesis in vitro has been limited, and there has been little progress in the expansion of human HSCs for clinical application. To that end, we defined a mesenchymal stem cell co-culture system based on a monoclonal OP9 stromal cell line (OP9M2), for expansion of clonally multipotent human HSPCs that were protected from apoptosis and immediate differentiation, and retained the HSPC phenotype. more...

(Submitter supplied) We identified a novel HSC regulatory gene, MYCT1 (MYC target 1), that is selectively expressed in undifferentiated human HSPC and is critical for human HSC expansion and engraftment. MYCT1 knockdown (KD) in human fetal liver and cord blood (CB) HSPCs impaired expansion ex vivo and engraftment after transplantation, whereas restoring the compromised MYCT1 expression via lentiviral overexpression (OE) in cultured human CB HSPCs improved ex vivo expansion of the most undifferentiated human HSPCs (CD34+CD38-CD90+CD45RA-EPCR+ITGA3+) and enhanced their engraftment ability. more...
