| Title |
ECFC_Tal1KD_Rep2 |
| 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.

| 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.
