Physiological processes in multicellular organisms depend on the function and interactions of specialized cell types operating in context. Some of these cell types are rare and thus obtainable only in minute quantities. For example, tissue-specific stem and progenitor cells are numerically scarce, but functionally highly relevant, and fulfill critical roles in development, tissue maintenance, and disease. Whereas low numbers of cells are routinely analyzed by genomics and transcriptomics, corres ...[more]

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+).

Expression data from human hematopoietic stem and progenitor compartments from patients with acute myeloid leukemia with monosomy 7 and healthy controls

Project description:We applied a novel approach of parallel transcriptional analysis of multiple, highly fractionated stem and progenitor populations in a genetically defined subset of AML (AML with monosomy 7). We isolated phenotypic long-term HSC (LT-HSC), short-term HSC (ST-HSC), and committed granulocyte-monocyte progenitors (GMP) from individual patients with AML, 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 bearing monosomy 7 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+).

Comparing gene expression in stem/progenitor cells from patients with CML in chronic, accelerated and blastic phase with normal volunteers

Project description:A comparison of global gene expression between rigorously defined stem and progenitor cells from patients with chronic myeloid leukaemia (CML) in chronic (CP), accelerated (AP) and blastic (BC) phase and similar populations isolated from normal volunteers. Cryopreserved CD34+ enriched cell populations obtained from patients with CML in CP, AP or BC at diagnosis prior to treatment -- or from normal volunteers -- were thawed and flow sorted into rigorously defined sub-populations (HSC, MPP, CMP, GMP and MEP -- using surface phenotype as described below). Total RNA was obtained and global gene expression measured following hybridisation to Affymetrix HuGene-1_0-st-v1 gene-chips. In total, 3 normal patient samples were compared with 6 CP, 4 AP and 2 BC samples. HSC, CMP, GMP and MEP populations were obtained from all specimens, MPP populations were obtained from normal, AP and BC specimens but not CP specimens.

Functionally distinct subsets of lineage-biased multipotent progenitors control blood production in normal and regenerative conditions

Project description:To identify the molecular characterisitics of parallel lineage-biased MPP populations arising from hematopoietic stem cells (HSC) we conducted genome-wide analyses of hematopoietic stem, progenitor and mature myeloid cell populations using Affymetrix Gene ST1.0 arrays. Microarray analysis of 3-5 biological replicates of the indicated hematopoietic populations, isolated by FACS sorting from C57BL/6 mouse BM. Immunophenotypic definitions: Long-term HSC (HSCLT) (Lin-/cKit+/Sca1+/Flk2-/CD48-/CD150+); Short-term HSC (HSCST) (Lin-/cKit+/Sca1+/Flk2-/CD48-/CD150-); MPP2 (Lin-/cKit+/Sca1+/Flk2-/CD48+/CD150+); MPP3 (Lin-/cKit+/Sca1+/Flk2-/CD48+/CD150-); MPP4 (Lin-/cKit+/Sca1+/Flk2+); CMP (Lin-/cKit+/Fc?R-/CD34+); GMP (Lin-/cKit+/Fc?R+/CD34+); Pre-granulocyte (PreGr) (Mac1+/Gr1int); Granulocyte (Gr) (Mac1+/Gr1hi). HSC and GMP samples listed here were also used as controls for our related microarray study GSE48893.

Transcription profiling of human CD34+ subsets in chronic phase CML and healthy individuals

Project description:A characteristic of chronic phase CML is accumulation of mature cells in the peripheral blood. It has not been determined if this expansion is explained by the CD34+ cell subset composition. We conducted flowcytometry-based cell sorting to assess the CD34+ subset composition and to retrieve the respective cells. We found a significant increase in the proportion of MEP and a decrease of HSC and GMP in patients with chronic phase CML compared to their healthy counterparts. The absolute number of HSC was similar, whereas CMP, GMP and MEP were expanded 2.8- to 7.7-fold. Gene expression analysis of CD34+ cell subsets showed, that in contrast to the normal developmental hierachy, CML HSC have a transcriptional profile which is similar to CML progenitor subsets and healthy CMP. HSC in healthy individuals show greater distance to their more mature progeny within the developmental hierarchy. As the differences between CML and healthy controls were minor at the progenitor level, we focused on the further characterization of CML HSC. 614 genes were differentially expressed, including downregulation of genes involved in adhesion and migration, regulation of the stem cell pool, and differentiation. We also found abrogation of nuclear receptors NR4A1 and NR4A3, and decreased expression of c-Jun and JunB. Re-expression of c-Jun and JunB in CD34+ cells from CML patients was achieved by co-transfection of NR4A1 and NR4A3. Moreover, we functionally corroborated a decreased adhesion capacity of the CML HSC. Taken together, these findings help to explain the hematological phenotype of CML patients in chronic phase. Experiment Overall Design: CD34+ subsets of 6 patients with chronic phase CML and 5 healthy volunteers were analysed by means of gene expression profiling with the Affymetrix HU-133A 2.0 array
