| Extraction protocol |
ChIP was performed as previously described (Ci et al., Blood, 2009). Briefly, 108 cells were fixed with 1% formaldehyde, lysed, and sonicated (Branson Sonicator; Branson) leading to a DNA average size of 200 bp. Five µg of antibodies were added to the precleared sample and incubated overnight at 4°C. The complexes were purified using protein-A beads (Roche) followed by elution from the beads and decrosslinking. DNA was purified using PCR purification columns (QIAGEN).
ChIP-seq and RNA-seq libraries were prepared using the Illumina ChIP-Seq and TruSeq RNA sample kits, respectively, according to the manufacturer. Libraries were validated using the Agilent Technologies 2100 Bioanalyzer and Quant-iT™ dsDNA HS Assay (Life Technologies)

genome build: mm9
Illumina Casava1.8 software used for basecalling.
RNA-seq data was aligned to transcripts using TopHat with default parameters. ChIP-seq data was aligned to the appropriate genome using ELAND.
FPKM were obtained using CuffLinks with upper-quartile and GC normalization
H3K4me3 ChIP-seq reads were called into peaks using the ChIPseeqer framework (p<10-15 and fold-change over input threshold 2) (Giannopoulou and Elemento, 2011) and H3K27me3 and EZH2 ChIP-seq reads were quantified in 1kb bins genome-wide, identifying regions of enrichment as consecutive bins with read counts greater than one standard deviation of the genome-wide mean.
Supplementary_files_format_and_content: tab-delimited FPKM values for each Refseq transcript; WIG files were generatedand peak files were called using ChIPseeqer framework (http://physiology.med.cornell.edu/faculty/elemento/lab/chipseq.shtml)
