| Title |
donor2_CD34+_d0 |
| Sample type |
genomic |
| |
|
| Source name |
Hematopoietic stem and progenitor cells from umbilical cord blood
|
| Organism |
Homo sapiens |
| Characteristics |
donor: donor2
cell type: CD34+ fraction
passage: freshly isolated
|
| Treatment protocol |
CD34+ cells were isolated from fresh umbilical cord blood after written consent according to the guidelines specifically approved by the Ethic Committee of RWTH Aachen University (Permit Number: EK187/08) using the CD34 Micro Bead Kit on a MiniMACS system (Miltenyi Biotec GmbH, Bergisch-Gladbach, Germany). Cells were cultured in StemSpan serum free expansion medium (Stem Cell Technologies, Grenoble, France) supplemented with 10 µg/mL heparin (ratiopharm, GmbH, Ulm, Germany), 20 ng/mL thrombopoietin (TPO; PeproTech GmbH, Hamburg, Germany), 10 ng/mL stem cell factor (SCF; PeproTech), 10 ng/mL fibroblast growth factor 1 (FGF1; PeproTech). Culture was either performed on tissue culture plastic (TCP) or on a confluent layer of mesenchymal stromal cells (MSCs; passage 3 to 6). After seven days, CD34+ and CD34- fractions were again separated as described above.

|
| Label |
Cy5 and Cy3
|
| Label protocol |
Standard Infinium HD Methylation Assay protocol
|
| |
|
| Hybridization protocol |
Bisulfite converted DNA was amplified, fragmented and hybridized to Illumina Infinium HumanMethylation450 Beadchip using standard Infinium HD Methylation Assay protocol.

| Scan protocol |
Standard Infinium HD Methylation Assay protocol
|
| Data processing |
Initial analysis was performed by the Genomestudio 2010.3 (Modul M Version 1.8.5). Data were normalized with internal controls according to Illumina´s standard procedures. Methylation level at each locus was calculated with the GenomeStudio Methylation module as beta-value (ranging from 0 to 1). The number of beads per feature varies between chips and beta-values were calculated as average of at least three technical replica.
