For RNA-Seq experiments, Total RNA was extracted using the Nucleospin RNA Extraction kit.For ChIP-Seq experiments, after differentiation to the desired stage, cells were dual crosslinked in plate with 1.5mM EGS and 1% formaldehyde. The fixation was then quenched with 125mM glycine. Cells were then washed twice and scraped in ice-cold PBS and resuspended in sonication buffer. For RNA-Seq experiments, 300ng of total RNA was poly-A selected and reverse transcribed using Illumina's TruSeq stranded mRNA library preparation kit (Illumina; 20020595). For ChIP-Seq experiments, DNA libraries were prepared using 1-5 ng of starting material using the SMARTer ThruPLEX DNA-Seq kit (Takara; R400674) according to manufacturer's instructions.
