Expression data from human CD34+ HPC subpopulations isolated from umbilical cord blood (Haddad et al. Blood 104:3918, 2004)

ABSTRACT: We used microarrays to analyze the gene expression profile of CD34+CD45RA+CD7+, CD34+CD45RA+CD10+CD19- and CD34+CD45+CD7-CD10-CD19- HPCs isolated from umbilical cord blood CD34+CD45RA+CD7+(CD10-) and CD34+CD45RA+CD10+(CD7-CD19-) HPCs correspond respectively to prothymocytes and early pre-proB precursors. CD34+CD45RA+CD7-CD10-CD19- HPCs correspond to lympho-granulo-macrophagic precursors

Expression data from human CD34+ HPC subpopulations transduced with nuclear-trapped AF1q/MLLT11 (A2M)

Project description:We used microarrays to examine the impact of AF1q/MLLT11 on the gene expression profile of CD34+CD45RA-Lin- and CD34+CD45RA+Lin- HPCs isolated from umbilical cord blood CD34+CD45RA-Lin- and CD34+CD45RA+Lin- HPCs correspond respectively to early multipotent and lympho-granulo-macrophagic precursors. A2M is a nuclear mutant-derivative of AF1q/MLLT11 CD34+CD45RA-Lin- and CD34+CD45RA+Lin- HPCs were FACS-sorted, exposed to A2M or control vectors, sorted based on GFP expression, and subjected to global gene expression analysis 72 hrs later.

Functional and transcriptional heterogeneity of human hemopoietic lympho-myeloid progenitors

Project description:Cord blood (CB) samples from normal donors were obtained with informed consent. Fresh CB samples were processed within 18-34h after collection. Mononuclear cells were isolated and CD34+ fraction was separated. CB CD34+ enriched fraction was lineage depleted by staining with purified anti-human CD2, CD3, CD4, CD7, CD8a, CD11b, CD14, CD19, CD20, CD56, CD235a followed by Qdot 605 conjugated goat F(ab')2 anti-mouse IgG (H+L). Cells were also stained with anti-human CD38-FITC, CD45RA-PE or -BV650, CD123-PE Cy7, CD90-biotin, CD34- PerCP and CD10-APC. Finally, cells were incubated with streptavidin-conjugated APC-eF780 and Hoechst 33258 (Invitrogen, final concentration: 1 g/ml). Populations were defined, as follows: HSC - Lin-CD34+CD38-CD90+CD45RA-CD10-, MPP - Lin-CD34+CD38-CD90-CD45RA-CD10-, LMPP - Lin-CD34+CD38-CD90-/loCD45RA+CD10-, MLP - Lin-CD34+CD38-CD90-/loCD45RA+CD10+, GMP - Lin-CD34+CD38+CD123+CD45RA+CD10-, CMP - Lin-CD34+CD38+CD123+CD45RA-CD10-, MEP - Lin-CD34+CD38+CD123-CD45RA-CD10-.

Expression data from Notch-activated CD34+CD45RA-Lin- hematopoietic progenitor cells (HPCs) transduced with nuclear-trapped AF1q/MLLT11 (A2M)

The transcriptional architecture of early human hematopoiesis identifies multilevel control of lymphoid commitment.

Project description:Here we tracked transcriptome changes over ten human hematopoietic stem and early progenitor populations, defining the transcriptional dynamics underlying the first steps of commitment. Most of the transcriptional programs observed extended beyond lineage boundaries. In particular, multi-lymphoid progenitors (MLPs) presented a hybrid transcriptional state with elements of lymphoid and myeloid programs, but also stem cell characteristics. Total RNA was obtained from flow-sorted populations of human cord blood based on the cell surface expression of CD34, CD38, CD45RA, Thy1, and CD49f, CD10, CD7, CD19 and CD1a.

Expression data from infant ALL with MLL-AF4 rearrangement

Expression data from infant ALL with MLL-AF4 rearrangement

Project description:MLL-AF4+ blasts from infant B-ALL, CB-derived CD34+CD38-CD19-CD33- HSC, CB-derived CD34+CD19+CD33- B-cell HPCs and CB-derived CD34+CD33+CD19- myeloid HPCs. We used microarray to estudy gene expression profile comparing ALL vs HSC, HPC and myeloid HPSC. We used highly FACS-purified (purity>98%) MLL-AF4+ blasts from infant B-ALL, CB-derived CD34+CD38-CD19-CD33- HSC, CB-derived CD34+CD19+CD33- B-cell HPCs and CB-derived CD34+CD33+CD19- myeloid HPCs. For each independent sample technical duplicates were always performed. Total RNA was extracted using TRIol reagent, and quantified on a Nanodrop spectrophotometer and Bioanalyzer. High-quality RNA was reverse transcribed and the obtained cDNA was used as a template to synthesize biotinylanted cDNA, then was fragmented and hybridized as duplicates/triplicates to HG-U133 plus2.0 GeneChips (Affymetrix) according to manufacturer's guideline.
