Sample GSM877121 Query DataSets for GSM877121
Status Public on Feb 08, 2013
Title CD31 Positive Cells + Hypoxia (1.5-2% O2) Replicate 2
Sample type RNA
Source name CD31 Positive Wild Type Mouse CCE ES Cells+Hypoxia (1.5-2% O2) Replicate 2
Organism Mus musculus
Characteristics gender: Male
cell line: CCE (129/Sv)
cell type: ES cells
genotype: Wild type
marker: CD31 positive
treatment: Hypoxia (1.5-2% O2)
time: 4 days
Treatment protocol 10,000 ES cells/ml were aggregated as embryoid bodies (EB) in 20 ul drops and differentiated for 4 days in IMDM medium, 15% FBS (Gibco), 150 uM monothioglycerol, and 50 ug/ml Ascorbic acid (Sigma). On day 4, EBs were harvested and dissociated, stained for Flk1 and sorted to purity using flow cytometry. 50,000 Flk1+ cells/ml were plated on collagen type IV (BD Bioscience) coated plates in biological triplicates and differentiated for 4 additional days in normoxia (21% O2) or hypoxia (1.5-2% O2) with or without 4 umol/l L-685.458 (BachemAG) in the same IMDM medium.
Growth protocol Wild type mouse CCE ES cells were cultured on gelatin coated plates in Glasgow MEM (Sigma) supplemented with 15% FBS (Hyclone), 1000 IU/ml LIF, 0.1 mM 2-mercaptoethanol and 0.1 mM Non-Essential Amino Acids (Gibco). Medium was changed daily and cells passaged every second day.
Extracted molecule total RNA
Extraction protocol >50,000 CD31+ cells were FACS sorted from each sample and total RNA was extracted using the RNeasy Micro kit (Qiagen, Germany).
Label Cy3
Label protocol 300ng of total RNA from each sample was reverse transcribed into cDNA and in vitro transcribed into biotin-labeled cRNA using the Illumina TotalPrep RNA Amplification kit (Ambion, USA).
Hybridization protocol 750ng of cRNA from each sample was hybridized to MouseRef-8 v2.0 Expression BeadChip microarrays (Illumina, USA) as per manufacturer specifications.
Scan protocol Microarrays were scanned on the BeadArray Reader (Illumina, USA) at scan factor 1 as per manufacturer specifications.
Data processing Raw intensity values were subjected to background subtraction performed on the BeadStudio Data Analysis software (Illumina, USA) and normalized using the Cross-correlation method (Chua et al., 2006). Differentially expressed transcripts were identified based on the mean Log2 fold change in expression values compared to the average of the normoxia controls, with a minimum cutoff at 1.5-fold change.
