| Title |
Shef1, hESC |
| Sample type |
RNA |
| |
|
| Source name |
Undifferentiated hESCs
|
| Organism |
Homo sapiens |
| Characteristics |
time: Day 0
cell line: Shef1
treatment: none
|
| Treatment protocol |
Undifferentiated hESCs were dissociated with Trypsin -EDTA (Sigma) and the cell suspension passed through a 100-micrometer cell strainer (BD Labware). Cells were plated onto laminin-coated plastic and incubated with DFNB medium (DMEM/high glucose: F12 mixed as 1:1, with N2 and B27) supplemented with FGF3 (50ng/ml) and FGF10 (50ng/ml) or with DFNB alone, without FGFs. Cells were allowed to differentiate for 14 days.
|
| Growth protocol |
hESC lines H14, Shef1 and Shef3 were maintained on inactivated mouse embryonic fibroblast (MEF) feeder cells in medium comprised of knockout Dulbecco’s modified Eagle’s medium supplemented with 20% knockout serum replacement (KOSR), 1% nonessential amino acids, 2mM L-glutamine, (all from Invitrogen), 0.1mM ß-mercaptoethanol (Sigma), and 4ng/ml of basic fibroblast growth factor (bFGF; R&D systems).
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was extracted using the RNAeasy Kit (Qiagen) following the manufacturer's instructions
|
| Label |
Biotin
|
| Label protocol |
200ng of total RNA was amplified using the 3' IVT method and biotinylation of antisense RNA carried out according to Affymetrix protocol
|
| |
|
| Hybridization protocol |
12.5µg of cRNA molecules were heat fragmented and applied to the Human Genome U133 plus 2 GeneChip in a hybridisation solution according to the Affymetrix protocol. Hybridisation took place overnight in a rotating hybridisation platform at 45°C for 16 hours. Post hybridisation stringency washing was done using the Affymetrix fluidics station again following the protocol outlined in the Affymetrix instructions
|
| Scan protocol |
the GeneChips were scanned in the Affymetrix GCS3000 scanner and the resultant image processed using the GCOS software package to prepare the .CEL files
|
| Data processing |
Normalization and initial analysis were done using puma (www.bioconductor.org) that estimates gene expression levels using probabilistic models
