Cells were exposed to TPA at 50nM and were harvested at 0, 1, 3, 6, 12 18, 24, 30, 36, 42, 48, 72, 96, 168 hours after TPA treatment for RNA purification.
Growth protocol
Human ES cells (H9 cell line) were cultured in human ES cell culture medium preconditioned with irradiated mouse embryonic fibroblasts (MEF) on Matrigel (BD Biosciences, Bedford, MA) as described (Xu C, Inokuma MS, Denham J, et al. Feeder-free growth of undifferentiated human embryonic stem cells. Nat Biotechnol. 2001;19:971-974). For routine maintenance, cells were passaged with 1mg/ml Collagenase (Invitrogen Corporation, Carlsbad, CA). For the TPA treatment time course experiment, cells were individualized with 0.05% Trypsin-EDTA, and seeded at 2 X 106 cells per 10 cm tissue culture dish. Twenty-four hours later, the cells formed small colonies with relatively uniform size (20-30 cells per colony).
Extracted molecule
total RNA
Extraction protocol
Total RNA was prepared with RNeasy Mini Kit (Qiagen, Inc., Valencia, CA) and subjected to on-column DNase treatment.

Description
the second channel (genomic DNA) serve as common reference across the experiments
Data processing
1. Image extraction: NimbleScan provided by NimbleGen is used to extract signal data from image files (*.TFF). Signal meansurements were saved in .pair files. 2. Normalization: Signal intensities from RNA and gDNA samples are normalized with Robust Multiple-chip Analysis (RMA) algorithm (Irizarry et al., 2003) separately. A median-adjusted ratio is calculated for each gene by dividing its signal intensity from the RNA sample by the sum of the corresponding signal intensity from the gDNA sample and median signal intensity of all genes from the gDNA channel.
