(Submitter supplied) The regenerative potential of human hematopoietic stem cells (HSCs) is well established by to their ability of life-long blood cell production and cure of a wide range of hematological diseases upon transplantation. This regenerative potential depends on HSC self-renewal and the coordinated adaptation to metabolic stress conditions. This is especially critical during ex vivo culture/manipulation of HSCs that is frequently accompanied with loss of self-renewal potential resulting in stem cell exhaustion. more...

(Submitter supplied) PPARγ antagonist GW9662 treatment could enhance ex vivo expansion of human cord blood hematopoietic stem and progenitor cells (HSCs/HPCs). To gain mechanistical insights into how antagonizing PPARγ promotes expansion of HSCs/HPCs, we performed RNA sequencing (RNA seq) analysis to identify genes involved in this process. Loss of function of PPARγ in CB CD34+ cells resulted in downregulation of a number of differentiation associated genes, including CD38, CD1d, HIC1, FAM20C, DUSP4, DHRS3 and ALDH1A2, suggesting that PPARγ antagonist may maintain stemness of CB CD34+ cells, at least in part by preventing differentiation. more...

(Submitter supplied) Cell purification technology combined with whole transcriptome sequencing and small molecule agonist of hematopoietic stem cell self-renewal has allowed us to identify ITGA3 as a surface maker that defines a rare subpopulation of human cells which is highly enriched for stem cell activity in vivo. ITGA3-positive cells (within the EPCR+CD90+CD133+CD34+CD45RA- fraction) exhibit a robust multi-lineage differentiation potential and serial reconstitution in immunocompromised mice. more...

(Submitter supplied) We demonstrate that a distinct hematopoietic stem cell gene expression signature was upregulated in human CD34+ cells cultured with Delta1ext-IgG in hypoxia compared to normoxic cultures. Data were submitted on behalf of Dr. Larochelle's lab at the NIH.

(Submitter supplied) We demonstrate that ex vivo culture of human adult hematopoietic stem and progenitor cells with Delta1ext-IgG under hypoxia limits endoplasmic reticulum stress in long-term repopulating hematopoietic stem cells and, to a lesser extent, in lineage committed progenitors compared to normoxic cultures. Data were submitted on behalf of Dr. Larochelle's lab at the NIH.

(Submitter supplied) Ex-vivo culture conditions used to expand the numbers of hematopoietic stem cells (HSCs) present within an umbilical cord blood (UCB) unit create cellular stresses leading to loss or at best maintenance of the primitive HSCs. Recently, we have shown that treatment with a histone deacetylase inhibitor, valproic acid (VPA), increases substantially the numbers of transplantable HSCs from UCB-CD34+ cells. more...

(Submitter supplied) Glycogen synthase kinase-3β (GSK-3β) has been recently identified as an important regulator of stem cell function. In vitro studies show that GSK-3β inhibition delays proliferation of human haematopoietic progenitor cells while increasing numbers of late dividing multipotent progenitors. Gene expression analysis revealed that GSK-3β inhibition modulates the expression of a subset of genes that are transcriptional targets for cytokines. more...

(Submitter supplied) We report the gene expression profile of single cell peripheral CD3+ cells from immunodeficient mice injected with human progenitor T-cells (proT-cells). ProT-cell subsets were generated in vitro using human umbilical cord blood-derived CD34+ cells that were either non-expanded (naive), or expanded in vitro with the hydrocarbon receptor antagonist, StemRegenin-1 (SR1).

(Submitter supplied) The scarcity of hematopoietic stem cells (HSCs) restricts their use in both clinical settings and experimental research. Here, we examined a recently developed method for expanding rigorously purified murine HSCs ex vivo. Input HSCs displayed varying potential for ex vivo self-renewal, with alternative outcomes revealed by single cell multimodal RNA- and ATAC-seq profiling. While most HSC progeny offered only transient in vivo reconstitution, these cells efficiently rescued mice from lethal myeloablation. more...
