| Characteristics |
cell line: WIBR3
cell type: Embryonic stem cells
culture condition: Naive
genotype: untransfected
|
| Treatment protocol |
Human ESCs were infected with the lentivirus in the presence of 6 ug/ml polybrene (Millipore). Infected cells were plated on mitomycin C inactivated DR4 feeder cells and selected with 1 ug/ml of puromycin for 5 days since 48 h after transduction.

| Growth protocol |
Conventional (primed) human ESCs were maintained on mitomycin C inactivated mouse embryonic fibroblast (MEF) feeder layers and passaged using Collagenase (1 mg/mL) or manual methods. Primed human ESCs were cultured in human ESC medium (hESM) [DMEM/F12 (Invitrogen) supplemented with 15% fetal bovine serum (Gibco HI FBS, 10082-147), 5% KnockOut Serum Replacement (Invitrogen), 2 mM L-glutamine (MPBio), 1% nonessential amino acids (Invitrogen), 1% penicillin-streptomycin (Lonza), 0.1 mM β-mercaptoethanol (Sigma) and 4 ng/ml FGF2 (R&D systems)]. Naive human ESCs were cultured on mitomycin C-inactivated MEF feeder cells, and were passaged by a brief PBS wash followed by single-cell dissociation using 3-5 minute treatment with Accutase (Gibco) and centrifugation in fibroblast medium [DMEM (Invitrogen) supplemented with 10% FBS (Gibco HI FBS, 10082-147), 2 mM L-glutamine (MPBio), 1% nonessential amino acids (Invitrogen), 1% penicillin-streptomycin (Lonza) and 0.1 mM β-mercaptoethanol (Sigma)]. For conversion of pre-existing primed human ESC lines, we seeded 2 x 105 trypsinized single cells on a MEF feeder layer in hESM supplemented with ROCK inhibitor Y-27632 (Stemgent, 10 μM). 2 days later medium was switched to 5i/L/A or 4i/L/A (no IM12)-containing naive human ESC medium. Following an initial wave of cell death, naive colonies appeared within 10 days and were expanded polyclonally using Accutase (Gibco) on a MEF feeder layer. Naive human pluripotent cells were derived and maintained in serum-free N2B27-based media supplemented with inhibitors and cytokines. 500 mL of medium was generated by including: 240 mL DMEM/F12 (Invitrogen; 11320), 240 mL Neurobasal (Invitrogen; 21103), 5 mL N2 supplement (Invitrogen; 17502048), 10 mL B27 supplement (Invitrogen; 17504044), 10 μg recombinant human LIF (made in-house), 2 mM L-glutamine (MPBio), 1% nonessential amino acids (Invitrogen), 0.1 mM β-mercaptoethanol (Sigma), 1% penicillin-streptomycin (Lonza), 50 µg/ml BSA (Gibco Fraction V, 15260), and the following small molecules and cytokines: PD0325901 (Stemgent, 1 μM), IM-12 (Enzo, 1 μM or 0 µM), SB590885 (R&D systems, 0.5 μM), WH4-023 (A Chemtek or Selleckchem, 1 μM), Y-27632 (Stemgent, 10 μM) and Activin A (Peprotech, 10 ng/mL). All naïve hESC experiments were conducted in 5% O2, 5% CO2.

total RNA |
| Extraction protocol |
Total RNA was isolated using the E.Z.N.A. total RNA kit I.
Library construction was performed using the SMARTer Directional cDNA Library Construction Kit (Clontech, 634933). Libraries were sequenced on an Illumina HiSeq3000 1 × 50 platform.

| Data processing |
Reads were aligned to the genome using TopHat (v2.0.10) and Bowtie2 (v2.1.0) with the default parameter settings.
Transcript assembly and differential expression analysis were performed using Cufflinks (v2.1.1). Assembling of novel transcripts was not allowed (-G), other parameters of Cufflinks followed the default setting.
