Identification and characterization of human Natural Killer (NK) lineage restricted progenitors

ABSTRACT: Natural killer (NK) cells represent one of three lymphoid lineages and play a vital role in controlling viral infections and cancer. In contrast to B and T lymphopoiesis where cellular and regulatory pathways have been extensively characterized, the cellular stages of early human NK-cell commitment remain poorly understood Here we described a novel NK-lineage restricted progenitor (NKP) in fetal development, umbilical cord blood and adult bone marrow. We used microarrays to detail the global programme of gene expression genes of this new progenitor. Global gene expression analysis was performed on the NKP, multipotent progenitors LMPP, common lymphoid progenitor candidate and mature NK cells purified from Cord blood CD34+ cells (3-4 replicates, 2 experiments)

Transciption profiling by array of human umbilical cord blood stem cells after co-culture with or without resting or IL-15 activated cord blood NK cells

Project description:Cord blood stem cells (CBSC) and resting or activated NK cells were co-cultured for 4 h and then CBSC were re-isolated by sorting using a FACSAria cell sorter (BD Biosciences). RNA was isolated from sorted CBSC using an RNeasy Micro kit (Qiagen). Samples were processed using GeneChip Whole Transcript Sense Target Labeling assays using the Ambion WT Expression kit and Affymetrix GeneChip WT Terminal Labeling and Controls kit (Affymetrix). The resulting ssDNAs were hybridized to the Human Gene 2.0 ST Array (Affymetrix) and transcript levels compared to CBSC alone using GeneSpring software.

Hematopoietic progenitors from differentiating RUNX1cGFP human embryonic stem cells

Project description:In order to identify cells expressing RUNX1c during hematopoietic differentiation of human embryonic stem cells (hESCs), we targeted GFP downstream of the RUNX1 distal promoter. GFP was observed from 10-25 days of embryoid body differentiation and accurately mirrored expression of the endogenous RUNX1c isoform. GFP was restricted to CD45+ hematopoietic cells and GFP+CD34+ cells were highly enriched for progenitor cells. Appearance of the first wave of hematopoietic blast colony forming cells (Bl-CFC) in d3-4 embryoid bodies, antedated the expression of RUNX1c. These results confirm a role for RUNX1c in marking a second wave of hematopoietic progenitor cells in differentiating hESCs. The purpose of the cord blood samples was to perform comparison of them to the gene expression profiles of the Runx fractions - as the cord blood represents a heterogeneous mix of hematopoietic stem cells and multipotent progenitors cells.

Identification of the chemokine CCL28 as a growth and survival factor for human hematopoietic stem- and progenitor cells

Project description:To discover novel growth factors for hematopoietic stem- and progenitor cells (HSPCs), we have assessed cytokine responses of cord blood (CB)-derived CD34+ cells in a high-content growth factor screen. We identify the immunoregulatory chemokine (C-C motif) ligand 28 (CCL28) as a novel growth factor that directly stimulates proliferation of primitive hematopoietic cells from different ontogenetic origins. Microarrays are used to compare the expression profiles of HSPCs expanded in SCF, TPO and CCL28 respectively. HSPCs were cultured in Serum-Free Expansion Medium with SCF, SCF + TPO, and SCF + CCL28 respectively, and hybridised microarrays in triplicate.

Human RORM-NM-3t+ CD34+ cells are lineage-specified progenitors of group 3 RORM-NM-3t+ innate lymphoid cells

Project description:Group 3 innate lymphoid cells (ILC3) are defined by the expression of RORM-NM-3t, which is selectively required for their development. The lineage-specified progenitor cells of human ILC3 and their developmental site after birth remain undefined. Here we identified a novel population of human CD34+ hematopoietic progenitor cells (HPC) expressing RORM-NM-3t and sharing with ILC3 a distinct transcriptional signature. RORM-NM-3t+ CD34+ HPC were located in tonsils and intestinal lamina propria (LP) and selectively differentiated towards ILC3. Conversely, RORM-NM-3t- CD34+ HPC displayed commitment potential for both ILC3 and NK cells and the differentiation fate towards these two cell lineages was determined by cytokine and aryl hydrocarbon receptor (AhR) signaling. Thus, we propose that RORM-NM-3t+ CD34+ cells represent human lineage-specified progenitors of IL-22+ ILC3 and that tonsils as well as intestinal LP might be preferential sites of their differentiation. ILC3, NK cells and the CD34+ HPC subsets were sorted from tonsils of 6 distinct donors to purity above 95%. cRNA of the sorted cell populations was hybridized to an Agilent Whole Human Genome Oligo Microarrays (8x60K v2, Design ID 039494)

miR-125a Confers Multi-Lineage Long-Term Repopulating Stem Cell Activity to Murine and Human Hematopoietic Progenitors

Project description:Umbilical cord blood (CB) is a non-invasive, convenient and broadly used source of hematopoietic stem cells (HSCs) for allogeneic stem cell transplantation. However, limiting numbers of HSCs remain a major constraint for its clinical application. One feasible option would be to expand HSCs to improve therapeutic outcome, however available protocols and the molecular mechanisms governing the self-renewal of HSC are unclear. Here we show that ectopic expression of a single miRNA, miR-125a, in purified murine and human multipotent progenitors (MPP) resulted in increased self-renewal and robust long-term multi-lineage repopulation in transplanted recipient mice. Using quantitative proteomics and Western blot analysis, we identified a restricted set of miR-125a targets which revealed the involvement of the MAP kinase signaling pathway in conferring long-term repopulating capacity to multipotent progenitors in human and mice. Our findings offer the innovative potential to use MPP with enhanced self-renewal activity to augment limited sources of HSC to improve clinical protocols.

Identification of HIF1 and HIF2 target genes in human CB CD34+ cells

Project description:Although it has been shown that HIF1 and 2 fulfill essential roles within the hematopoietic system and in the regulation of HSC fate, little is currently known about the specific mechanisms that are involved. We identified transcriptome changes induced by hypoxia, constitutively active HIF1(P402/564) and HIF2(P405/531) in human cord blood CD34+ cells. Thus, we were able to identify common hypoxia-HIF1-HIF2 gene signatures, but we also identified specific target genes that were exclusively regulated by HIF1, HIF2 or hypoxia. CB CD34+ cells were isolated by Miltenyi miniMACS column. Cells were prestimulated in HPGM with 100 ng/ml KITL, FLT3L and TPO for 48 hrs. Cells were transduced with control pRRL-IRS2-EGFP lentiviral vectors or vectors expressing HIF1α(P402A,P564A) or HIF2α(P405A,P531A) in one or two rounds of 12 hrs each. 24 hrs later transduced cells were sorted after which RNA was isolated. 5 independent CB CD34+ batches were isolated, transduced and sorted, and isolated RNA was combined and used for Illumina beadhchip arrays HT12 v4

Remodeling of the DNA methylation landscape of CD34+ cells from fetal liver / cord blood upon upon CRISPR mediated t(4:11) rearrangements.

Project description:The prognosis of infant B-cell acute lymphoblastic leukemia (iB-ALL) remains dismal, especially in patients harboring the MLL-AF4 (KTM2A-AFF1) rearrangement, which arises prenatally in early hematopoietic stem/progenitor cells (HSPCs). MLL-AF4+ B-ALL shows a bimodal localization of the MLL gene breakpoint within the MLL break cluster region, and two subgroups of patients based on the gene expression pattern of the HOXA/MEIS cluster have been identified. The pathogenic mechanisms in MLL-AF4+ B-ALL are challenging to study functionally due to the absence of faithful human cellular models recapitulating the disease phenotype and latency. Here, we assess the molecular contribution and leukemogenic capacity of MLL breakpoints occurring in either intron 10 (MLLi10, centromeric) or intron 12 (MLLi12, telomeric) in ontogenically-different human HSPCs sourced prenatally (fetal liver) and neonatally (cord blood). CRISPR-Cas9-induced MLL-AF4 (MA) targeting either MLLi10 (Mi10A) or MLLi12 (Mi12A) causes MA-driven in vitro myeloid immortalization in both fetal liver- and cord blood-CD34+ HSPCs. The cellular ontogeny and the location of the MLL breakpoint influenced the capacity of MLL-edited CD34+ HSPCs to initiate pro-B-ALL in vivo, which faithfully recapitulated the molecular, transcriptomic and methylome profiles of patients with primary MA+ iB-ALL. This dataset contains the DNA methylation information (Illumina MethylationEPIC Beadchip platform) of MLL-edited CD34+ cells (i10 or i12). BCPs, used as controls, were obtained from E-MTAB-8505

Gene expression analysis for CD56- T, NK, CD56+ T cells, and iNKT cells

Project description:A small subset of T cells also expresses kiler-cell immunoglobulin-like receptors (KIRs). We find that KIR+ T cells primarily reside in the CD56+ T population. However, little is known on how these cells are different from the conventional CD56- T, NK, and iNKT cells. We used microarray profiling to compare and determine the distinctive differences of CD56+ T cell and its KIR subsets when compared to the conventional CD56- T, NK and iNKT cells. Lymphocyte subsets were sorted from human peripheral blood mononuclear cells with FACSAriaII (BD Biosciences, San Jose, CA) using anti-CD3, anti-CD56, anti-CD14, anti-KIR2DL1, anti-KIR2DL2/3, anti-KIR3DL1 and anti-TCRValpha24 antibodies. The purity of CD3+CD56- T cells, CD3-CD56+ NK cells, CD3+CD56+ T cells, KIR-CD3+CD56+ T cells, and KIR+CD3+CD56+ T cells were more than 98% in all experiments. The purities of iNKT cells for TCRValpha24 and CD1d-tetramer were >95% and >90%, respectively. RNA pre-amplification, labeling and hybridization on Human Genome U133Plus 2.0 GeneChip array were performed in the St. Jude Hartwell Center for Bioinformatics & Biotechnology microarray core facility according to the manufacturer’s instructions (Affymetrix, Santa Clara, CA).
