B cells develop in the mammalian bone marrow through a sequence of precursor stages, which can be ordered by the recombination status of their immunoglobulin loci. This developmental pathway is functionally similar between mice and man. However, whether this similarity is based on usage of the same genes is unknown. We show that large-scale gene expression patterns differ substantially between human and mouse B-cell development. Among 644 genes which were differentially expressed in 4 early stag ...[more]

ICL0011 - Host response in human Calu-3 cells to infection with A/Vietnam/1203-CIP048_RG3/2004 (H5N1) (PB1-F2 deletion), A/Vietnam/1203-CIP048_RG3/2004 (H5N1) (PB2-627E mutant) or WT: A/Vietnam/1203/2004 (H5N1)

Project description:Differential expression was determined in Calu-3 cells between mock infected and infection with one of 3 Influenza viruses (wild-type VN1203, VN1203 mutant PB1-F2del, VN1203 mutant PB2-627E) at different times post infection. Purpose: To obtain samples for transcriptional analysis in triplicate using the VN1203 pathogenicity mutants PB1-F2del and PB2-627E. Overview of Experiment: . Time Points: 0, 3, 7, 12, 18 and 24 hrs post infection. . There are two time points for wild type VN1203. . Done in triplicate. . Triplicates are defined as 3 different wells, plated at the same time using the same cell stock for all replicates. . Time-matched mocks were done in triplicate from the same cell stock as the rest of the samples. . Culture medium (the same as what the virus stock is in) was used for the mock infections. Calu-3 cells were infected with A/Vietnam/1203-CIP048_RG3/2004 (H5N1) (PB1-F2 deletion), A/Vietnam/1203-CIP048_RG3/2004 (H5N1) (PB2-627E mutant) or mock infected and samples were collected at 0, 3, 7, 12, 18 and 24 hpi. Calu-3 cells were infected with WT: A/Vietnam/1203/2004 (H5N1) and samples were collected at 7 and 24 hpi. There are 3 mock and 3 infected replicates for each time point. Expression profiles were determined.

Gene expression profiling in the leukemic stem cell-enriched CD34+ fraction identifies target genes that predict prognosis in normal karyotype AML

Project description:Mononuclear cells from AML patients (n=46) were sorted into CD34+ and CD34- subfractions and genome-wide expression analysis was performed using Illumina BeadChip Arrays (HT12 v3). Of 2 AML samples only the CD34+ fraction could be analyzed. AML CD34+ and CD34- gene expression was compared to a large group of normal CD34+ bone marrow cells (n=31). Mononuclear cells from AML patients (n=46) were sorted into CD34+ (46) and CD34- (44) subfractions and genome-wide expression analysis was performed using Illumina BeadChip Arrays (HT12 v3). AML CD34+ and CD34- gene expression was compared to a large group of normal CD34+ bone marrow cells (n=31).

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

Project description: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 The corresponding populations were sorted from total CD34+ HPCs isolated from 2 or 3 individual donors

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.

Single cell Ig VDJ sequencing (10X Genomics) of human blood B cells from SLE pateints and healthy controls

Project description:B cells positive for Ig kappa and Ig lambda are observed by flow cytometry in one fourth of patients with Systemic Lupus Erythematosus (SLE). Single cell Ig VDJ sequencing (10X Genomics) reveals that kappa/lambda B cells are at the same frequency (about 1.5%) in these SLE patients as in healthy controls. Cells observed by flow cytometry are instead decorated with VH4-34 IgM (kappa or lambda) autoantibodies that are present in some but not all SLE patients.

CD34 marks angiogenic tip cells in human vascular endothelial cell cultures.

Project description:The functional shift of quiescent endothelial cells into tip cells that migrate and stalk cells that proliferate is a key event during sprouting angiogenesis. We previously showed that the sialomucin CD34 is expressed in a small subset of cultured endothelial cells and that these cells extend filopodia: a hallmark of tip cells in vivo. In the present study, we characterized endothelial cells expressing CD34 in endothelial monolayers in vitro. We found that CD34-positive human umbilical vein endothelial cells show low proliferation activity and increased mRNA expression of all known tip cell markers, as compared to CD34- negative cells. Genome-wide mRNA profiling analysis of CD34-positive endothelial cells demonstrated enrichment for biological functions related to angiogenesis and migration, whereas CD34-negative cells were enriched for functions related to proliferation. In addition, we found an increase or decrease of CD34-positive cells in vitro upon exposure to stimuli that enhance or limit the number of tip cells in vivo, respectively. Our findings suggest cells with virtually all known properties of tip cells are present in vascular endothelial cell cultures and that they can be isolated based on expression of CD34. This novel strategy may open alternative avenues for future studies of molecular processes and functions in tip cells in angiogenesis. Four HUVEC donors were FACS-sorted by CD34 and divided in CD34-positive and CD34-negative fractions.

Expression data from human hematopoietic stem and progenitor compartments from patients with acute myeloid leukemia with normal karyotype and healthy controls

Project description:We applied a novel approach of parallel transcriptional analysis of multiple, highly fractionated stem and progenitor populations from patients with acute myeloid leukemia (AML) and a normal karyotype. We isolated phenotypic long-term HSC (LT-HSC), short-term HSC (ST-HSC), and committed granulocyte-monocyte progenitors (GMP) from individual patients, and measured gene expression profiles of each population, and in comparison to their phenotypic counterparts from age-matched healthy controls. Bone marrow samples from AML patients with normal karyotype and age-matched healthy controls were used in this study. Hematopoietic stem and progenitor compartments were purified by multiparameter-high speed fluorescence-activated cell sorting (FACS) from CD34+ enriched bone marrow to isolate LT-HSC (Lin-/CD34+/CD38-/CD90+), ST-HSC (Lin-/CD34+/CD38-/CD90-), and GMP (Lin-/CD34+/CD38+/CD123+/CD45R+).
