|
| Source name |
CD34pos, Donor B
|
| Organism |
Homo sapiens |
| Characteristics |
tissue: CD34pos
gender: female
|
| Treatment protocol |
MS patients (4 donors) and age matched healthy donors (5) underwent stem cell mobilization by G-CSF (2x5μg/kg/day)..
|

| Extraction protocol |
White blood cells, containing the CD34+ cell fraction, were collected by leucocytapheresis from peripheral blood, frozen and stored in liquid nitrogen. All samples were thawed and processed at one center and CD34+ cells purified by magnetic bead separation using the autoMACS system (Miltenyi). Purity and viability of CD34+ cells was analyzed by Fluorescence Activated Cell Sorter (FACS). Total cellular RNA and DNA were extracted with TRIzol reagent. RNA samples were checked for quantity, purity and integrity of the 18S and 28S ribosomal bands by capillary electrophoresis using the Agilent 2100 bioanalyzer (nanoassay).

| Label |
Cy3
|
| Label protocol |
Cyanine-3 (Cy3) labeled cRNA was prepared from 700 ng RNA using the Low RNA Input linear Amplification Kit Plus, One Color protocol (Agilent Techologies, Inc. 2007; Cat. N°: 51885339) and the Agilent RNA SpikeIn Kit for One color (Agilent Techologies, Inc. 2007; Cat. N°: 51885282). Quantity and efficiency of the labeled amplified cRNA were determined using the NanoDrop ND1000 UVVIS Spectrophotometer version 3.2.1.

|
| Hybridization protocol |
Cy3-labelled cRNA was hybridized to the Agilent miRNA microarray following manufacturers instructions followed by washing and staining according to the manufacturers recommendation.
|
| Scan protocol |
Cy3 intensities were detected by onecolor scanning using an Agilent DNA microarray scanner (Agilent) at 5 micron resolution. Scanned image files were visually inspected for artifacts and then analyzed
|
| Description |
Gene expression hematopoietic progenitor cells
|
| Data processing |
Slides were scanned using Agilent Microarray Scanner (G2565BA) followed by data extraction by Agilent Feature Extraction software version 9.5.3. with default settings for oligonucleotide expression arrays. Intensity data were processed with R and Bioconductor packages to obtain RMA-normalized and log2-transformed intensity values.
