Gene expression analysis of Human CD34+ cells derived from bone marrow, mobilized peripheral blood, umbillial cord blood using Agilent Whole Human Genome Oligo Microarrays (one-color)

ABSTRACT: In order to identify genes associated with the engraftment potential of human hematopoietic stem cells, we have employed whole genome microarray expression profiling of G0 and G1 phase CD34+ cells derived from bone marrow, mobilized peripheral blood, and umbilical cord blood. Samples were collected from healthy adult volunteers after obtaining informed consent according to the guidelines of the Investigational Review Board of Indiana University School of Medicine. CD34+ cells were selected and fractionated into G0 and G1 phases of cell cycle on a flow cytometer. Purity of sorted cells was further confirmed by qRT-PCR by measuring the relative expression of Ki67. Sorted cells were subjeccted to microarray analysis.

Purity of sorted cells was further confirmed by qRT-PCR by measuring the relative expression of Ki67. Sorted cells were subjeccted to microarray analysis. Three biological replicates of sorted and confirmed G0 and G1 cells from bone marrow, mobilized peripheral blood, and umbilical cord blood (total of eighteen samples) were subjected to microarray analysis. To generate distinct and unique sets of data, we did not pool multiple samples from any tissue studied so that each sample or its replicate was from a single donor.

Expression data of NIH3T3 in G0 and G1 phases

Project description:NIH3T3 in the middle of G0 to G1 transion consists of the cells which is still staying G0 phase and the cells which enters G1. Monitoring the expressions of p27 and Cdt1 enables to distinguish these two; p27+/Cdt1+ cells as the cells in G0 phase and p27-Cdt1+ cells as G1 phase We sorted p27+Cdt1+ (G0) NIH3T3 cells and p27-Cdt1+ (G1) NIH3T3 cells in the middle of G0-G1 transition, 5 hours after serum addition following the serum addition using mVenus-p27K- and mCherry-hCdt1(30/120) . We compared the expression profiles of these NIH3T3 cells in G0 and G1 phases and identified the genes upregulated in G0 or G1 phases. The p27+Cdt1+ (G0) NIH3T3 cells and p27-Cdt1+ (G1) NIH3T3 cells were sorted by FACS for RNA extraction and hybridization on Affymetrix microarrays.

Effect of glomerular disease on the podocyte cell cycle

Project description:Proteomic data from three populations of sorted murine podocytes using the FUCCI (fluorescence ubiquitination cell cycle indicator) Cell Cycle Sensor: Wild-Type podocytes at G0 (WT_G0), Alport Syndrome podocytes at G0 (AS_G0), and Alport Syndrome podocytes at G1 (AS_G1). Cell populations were sorted from murine kidney; ~10K cells were prepared using the MicroPOTS protocol (PMID: 30460388), digested with trypsin, then analyzed by LC-MS/MS. Data was searched with MaxQuant.

Transcription profiling of human CD133-positive G0 and G1 human ubmbilical vein cells

Project description:To identify regulators of human HSC fate, we transcriptionally profiled quiescent primitive cord blood (CB) CD133+ G0 cells enriched for long term culture initiating cell (LTC-IC) activity. CD133+ G0 cells were sorted by cell cycle status using combined DNA and RNA staining; less immature CD133+G1 cells served as a comparison.

Aged, Young and Restored Samples from Mobilized Peripheral Blood [miRNA]

Project description:We report the miRNA expression in each CD34+ cells and their exosomes in mobilized peripheral blood in aged, young, and aged/young samples cocultured in transwell. Restored samples refer to aged MPB co-cultured with young MPB in the transwell culture.

Leukemia reconstitution in vivo is driven by cells in early cell cycle and low metabolic state

Project description:To characterize LICs in ALL irrespective of surface markers expression, we investigated leukemia initiating activities of cellular subfractions of patient-derived xenograft BCP-ALL cells sorted according to different cell cycle phases (i.e. G0/G1 and G2/M) followed by transplantation onto NOD/SCID mice. All cell fractions led to leukemia engraftment indicating LIC activity irrespective of cell cycle stage. Most importantly, cells isolated from G0/G1 cell cycle phases led to early leukemia engraftment in contrast to cells from late cell cycle (G2/M). To further characterize cells with different engraftment potential in vivo, we analyzed the gene expression profiles of early (G1b early) and late (G2/M) engrafting cells.

Gene expression differences between highly enriched normal and chronic myelogenous leukemia quiescent stem/progenitor cells and correlations with biological abnormalities

Project description:In comparing gene expression of normal and CML CD34+ quiescent (G0) and proliferating (G1/S/G2/M) cells, 292 genes were down-regulated and 192 genes were up-regulated in the CML G0 cells. The differentially expressed genes were grouped according to their reported functions and correlations were sought with biological differences previously observed between the same groups. The most apparent correlations include: i) Normal and CML G0 cells are more primitive than G1/S/G2/M cells; ii) CML G0 cells are in a more advanced stage of development and more poised to begin proliferating than normal G0 cells; iii) When CML G0 cells are stimulated to proliferate, they undergo further differentiation and maturation more rapidly than normal G0 cells, but both granulopoiesis and erythropoiesis are less efficient than normal; iv) Whereas normal G0 cells form only granulocyte/monocyte (GM) colonies when stimulated by cytokines, CML G0 cells consistently form a combination of GM and erythroid clusters and colonies; and v) Prominin-1 (CD133) is the gene most down-regulated in CML G0 cells and its down-regulation appears to be associated with the spontaneous formation of erythroid colonies by CML progenitors without EPO. The gene most over-expressed in CML G0 cells is LepR, but its role in contributing to the myeloid expansion and other abnormalities is unknown. It was hoped that LepR might serve as a therapeutic target, but leptin had no stimulatory or inhibitory effect on either normal or CML G0 cells, our attempts to make a specific LepR antibody were unsuccessful, and no other potentially targetable over-expressed surface antigens were identified.

Project description:The label-free quantitative proteome was generated for 42 primary AML patient samples enriched for CD34+ cells (or mononuclear cells in the case of NPMcyt sameples) and as controls 6 mobilized peripheral blood CD34+ cells were included. Furthermore, 6 AML cell lines were included, and also primary mesenchymal stem cells grown under normaoxia or hypoxia were included.

Expression data for Mobilized Peripheral Blood CD34+ cells with Wnt or BMP stimulation

Project description:Analysis of mobilized peripheral blood CD34+ cells from a healthy volunteer under erythroid differentiation conditions with and without stimulation to the BMP or Wnt signaling pathways. For erythroid differentiation, expanded CD34+ cells were placed in Stemspan SFEM medium supplemented with 2% pen/strep, 20ng/ml SCF, 1U/ml Epo, 5ng/ml IL3, 2uM dexamethasone, and 1uM beta-estradiol. Arrays were performed 2 hours after addition of cytokines. For signaling pathway stimulation, cells were exposed to 0.5uM BIO (a GSK3 inhibitor) for Wnt pathway activation, 25ng/ml rhBMP4 for BMP pathway activation, or vehicle control for 2 hours. Three biological replicates were performed per treatment group. We used microarrays to detail the global program of gene expression changes after Wnt or BMP pathway stimulation in human CD34+ hematopoietic progenitors under erythroid differentiation conditions.
