| Title |
WTG4_Flk1_long_DexMinus_48h_rep1 |
| Sample type |
RNA |
| |
|
| Source name |
Flk1+/Ecad- mesoderm cells derived from mouse wild-type Gata4GR (WTG4) ES cells, -Dex, 48hr, replicate 1
|
| Organism |
Mus musculus |
| Characteristics |
cell line: Line J1G4.211
genotype/variation: wild-type, stably expressing Gata4-glucocorticoid receptor ligand binding domain fusion gene
cell type: Flk1+/Ecad- mesoderm cells derived from embryonic stem (ES) cells, with further culture
dexamethasone: no
time: 48h
|
| Treatment protocol |
The cells were collected using 0.25% trypsin-EDTA, and single cell suspensions were stained using APC-conjugated anti-Flk1, biotinylated anti-E-cadherin (Eccd2, Takara Bio or DECMA-1, eBioscience) antibodies, and PE-conjugated streptavidin. Flk1 positive/E-cadherin negative cells were sorted by FACS-Aria (BD Biosciences). The cells were further cultured on type IV collagen-coated dishes in the differentiation medium (alpha-MEM supplemented with 10% FCS and 50 uM 2-mercaptoethanol) for 48 hours in the absence of dexamethasone.
|
| Growth protocol |
ES cells were plated onto a 10-cm dish with confluent OP9 stromal cells in the differentiation medium (alpha-MEM supplemented with 10% FCS and 50 uM 2-mercaptoethanol) for 4 days.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was isolated by using the QIAshredder and the RNeasy Plus Micro Kit with gDNA Eliminator column (Qiagen) according to the manufacturer's protocols. RNA was quantified and quality controlled using the NanoDrop ND-1000 Spectrophotometer (Thermo) and the 2100 Bioanalyzer (Agilent).
|
| Label |
Cy3
|
| Label protocol |
Amplification and Cy3 labeling of RNA was prepared from 50 ng of RNA using the Low Input Quick Amp Labeling kit (Agilent) according to the manufacturer's instructions (G4140-90040 One-Color Microarray-Based Gene Expression Analysis Protocol Version 6.5). Purification of Cy3-labeled cRNA was performed using the RNeasy Mini Kit (Qiagen). Quantity, quality and dye incorporation of Cy3-labeled cRNA were checked using the NanoDrop ND-1000 Spectrophotometer (Thermo) and the 2100 Bioanalyzer (Agilent).
|
| |
|
| Hybridization protocol |
600 ng of Cy3-labeled cRNA was hybridized in Agilent hybridization chambers for 17 hours at 65 degrees C and 10 rpm according to the manufacturer's instructions (G4140-90040 One-Color Microarray-Based Gene Expression Analysis Protocol Version 6.5).
|
| Scan protocol |
Slide scanning was performed using the Agilent DNA Microarray Scanner G2505C with 3 um resolution and 20-bit dynamic range.
|
| Description |
Gene expression data from Flk1+/Ecad- mesoderm cells derived from wild-type Gata4GR ES cells, with further 48hr-culture in the absence of dexamethasone (without Gata4GR induction)
'short' sample represents short time course experiment (0-3h). In this experiment, dexamethasone was added before FACS sorting.
'long' sample represents long time course experiment (0-72h). In this experiment, dexamethasone was added after FACS sorting.
|
| Data processing |
The scanned images were processed with Feature Extraction Software 10.7.3.1 (Agilent) using default parameters (protocol GE1_107_Sep09 and Grid 028005_D_F_20110406) to generate background subtracted and spatially detrended green Processed Signal intensities. Normalize signal intensities were obtained by a) removal of data of control probes, b) log2 transformation, and c) quantile normalization, which was performed using the normalizeQuantiles function of the limma package of the R.
