| Title |
hES-T3 derived embryoid bodies, biological rep2 |
| Sample type |
RNA |
| |
|
| Source name |
The T3EB embryoid bodies were formed in 7 days from hES-T3 by mechanically dissection , and they resembled early embryo development to some extent
|
| Organism |
Homo sapiens |
| Characteristics |
gender: female
passage: 36
sample type: embryoid bodies derived from T3ES
|
| Treatment protocol |
Non
|
| Growth protocol |
The formation of embryoid bodies (EBs) was induced by mechanically dissecting undifferentiated hES-T3 colonies into pieces that were transferred and grown with very slow shaking (20 rpm) in the EB medium containing 80% knockout DMEM, 20% ES-qualified FBS (GIBCO), 1% non-essential amino acids, and 1 mM L-glutamine without MEF feeder layer in bacterial Petri dish plate(£\-plus, 10 cm) under 5% CO2 at 37oC for 7 days with change of medium every two days. These embryoid bodies are designated as T3EB.

| Extracted molecule |
total RNA |
| Extraction protocol |
Trizol extraction of total RNA was performed according to the manufacturer's instructions. Total RNAs extracted using TRIZOL reagent were quantified spectrophotometrically. The cDNA synthesis was carried out by using SUPERSCRIPTTM one-step RT-PCR kit (Invitrogen). For the reverse transcription step, the whole 5 ul of the resuspended RNAs were incubated for 60 min at 42oC, then 15 min at 72oC in 50 ul of reaction mixture containing 25 ul of 2x Reaction Mix (Invitrogen) and 1 ul of RT/PLANTINUM Taq Mix (Invitrogen). 28.5 ul of the cDNAs present in the 50 ul RT reaction mixture purified by Microarray Target Purification Kit (Roche Applied Science, Indianapolis, ID, USA, http://www.roche-applies-science.com) were used as templates to amplify cDNA by Microarray Target Amplification Kit. The amplified cDNAs were purified by Microarray Target Purification Kit, and complementary RNAs (cRNAs) were synthesized from 200 ng cDNA with Microarray RNA Target Synthesis Kit (Roche Applied Science).

| Label |
biotin
|
| Label protocol |
Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 5 micrograms purified cRNA (Expression Analysis Technical Manual, 2004, Affymetrix).
|
| |
|
| Hybridization protocol |
Following fragmentation, 10 micrograms of cRNA were hybridized for 16 hr at 45oC on Affymetrix Human Genome U133 plus 2.0 GeneChip. GeneChips were washed and stained in the Affymetrix Fluidics Station 400.
|
| Scan protocol |
GeneChips from the hybridization experiments were read by the Affymetrix GeneChip scanner 3000.
|
| Description |
The mRNA profiles from the undifferentiated human embryonic stem cell line hES-T3 (T3ES), hES-T3 derived embryoid bodies (T3EB) and hES-T3 differentiated fibroblast-like cells (T3DF) were quantitatively determined.
|
| Data processing |
The data were processed by GeneSpring software version 7.2 GC-RMA preprocessor to use on the CEL files
