| Treatment protocol |
20,000 MEFs at passage 2 were plated in a 12-well plate and then infected twice with retroviral stocks generated with Plat-E cells. 3 volumes of the supernatants of OSKM transcription factors were mixed with 1 volume of fresh MEF medium containing polybrene at a final concentration of 8 μg/ml. The infection efficiency was tested by MEFs transduced with virus of pMXs-EGFP. pMXs-CTCF and shRNAs were also transfected into OG2-MEFs by retrovirus generated from Plat-E cells. For infecting OG2-MEFs, the medium of OG2-MEFs was replaced with 2 ml of infection mixture per well in a 12-well plate. Infected cells were cultured with mESC medium containing 50 μg/ml Vitamin C (Sigma) post infection and renewed daily. For polycistronic OSKM-mediated reprogramming experiments, MEFs were transduced with 1 volume inducible lentivirus of OSKM and 2 volume rtTA retroviruses generated from HEK293T cells. Infected cells were cultured in mESC medium containing 50 μg/ml Vitamin C and 2 μg/ml doxycycline (Sigma) for 12 days to count GFP positive colonies. To ensure proper CTCF knockdown efficiency before transfecting these virus supernatants into MEFs, we concentrated virus supernatant produced from Ctcf shRNAs.

| Growth protocol |
mESCs and iPSCs were cultured in DMEM/High glucose medium (Hyclone) supplemented with beta-mercaptoethanol (10 mM), sodium pyruvate (10 mM), non-essential amino acids (10 mM), GlutaMAX (10 mM), 15% fetal bovine serum (Gibco), 1000 U/ml leukemia inhibitory factor (LIF), 1 μM MEK inhibitor PD0325901 and 3 μM GSK3 inhibitor CH99021. MEF cells were cultured in 10% FBS medium supplemented with non-essential amino acids (10 mM) and GlutaMAX (10 mM).

| Data processing |
RNA-seq raw datasets were qualified with FastQC tool and trimmed with trim galore if containing adaptors.
Reads were aligned to mm9 genome using rsem with options "--star". Counts were extracted from sample.genes.results file and merged together. RNA-seq raw counts were normalized with EDAseq.
Genome_build: mm9
Supplementary_files_format_and_content: tsv files were generated from normalized RNAseq data.
