Sample GSM1085538 Query DataSets for GSM1085538
Status Public on May 02, 2014
Title ECFC_Tal1KD_Rep3
Sample type RNA
 
Source name Human primary endothelial colony-forming cells
Organism Homo sapiens
Characteristics source: ECFCs derived from umbilical cord blood
treatment: Tal1 shRNA
Treatment protocol Paired samples were infected with lentiviruses expressing an anti-TAL1 shRNA or a scrambled shRNA as a negative control. Infection was done at a multiplicity of infection (MOI) of 100 twice at 24 hours interval in presence of 4μg/ml Hexadimethrine bromide.
Growth protocol Human umbilical cord blood from normal full-term deliveries were obtained after informed consent. Light-density mononuclear cell (MNC) fractions were isolated by Ficoll density and resuspended in complete EGM-2 medium (EBM-2 Endothelial Cell basal Medium-2, Lonza, Cat# CC-3156, supplemented with EGM-2 SingleQuot Kit Supplements & Growth Factors, Lonza, Cat# CC-4176) and 10% fetal bovine serum and plated on to CellBIND 6 well plates at 1x10^7 cells/well. Individual ECFC colonies were isolated with 0.05% trypsin and expanded in EGM-2 medium. ECFCs at passage 3 were used.
Extracted molecule total RNA
Extraction protocol DNA-free total RNA was isolated with the RNeasy Mini Kit following the manufacturer's protocol.
Label biotin
Label protocol Affymetrix standard protocol for GeneChip Whole Transcript Expression Arrays. Labeling performed at the StemCore Laboratories Affymetrix Microarray facility at the Ottawa Hospital Research Institute (Ottawa, Ontario, Canada).
 
Hybridization protocol Affymetrix standard protocol for GeneChip for cartridge arrays. Hybridization performed at the StemCore Laboratories Affymetrix Microarray facility at the Ottawa Hospital Research Institute (Ottawa, Ontario, Canada)
Scan protocol Affymetrix standard protocol for GeneChip for cartridge arrays. Scan performed at the StemCore Laboratories Affymetrix Microarray facility at the Ottawa Hospital Research Institute (Ottawa, Ontario, Canada).
Description Gene expression of Endothelial Colony Forming-Cell treated with an shRNA against Tal1
Data processing CEL files were imported into R/Bioconductor package 'affy'. The data was normalized using the RMA algorithm. Probes with variance under the 25th quantile were removed. Differential expression analysis was performed with the R/Bioconductor 'limma' package. Probes with Benjamini-Hochberg adjusted p-value lower than 0.05 were deemed as significant.
