attributes.value: iPSCs were seeded on Feeder and maintained in mESC medium. mESC medium contains 47% DMEM/F12, 47% Neural basal medium, 1 x N2 supplement, 1 x B27 supplement, 1% Glutamax, 1% nonessential amino acids (NEAA), 0.055 mM 2-mercaptoethanol (β-ME), 1% P/S, 1000 units/mL mLIF, 3 μM CHIR99021 and 0.2 μM PD0325901. MEFs were cultured in MEF medium, containing DMEM Basic, 10% fetal bovine serum (FBS), 1% penicillin and streptomycin (P/S). OG2 MEFs of passages 1-3 were seeded into 6-well plates at density of 2.5 x 10^4 cells/plate. On the next day, medium was changed to reprogramming medium. Medium was changed every 2 days. For reprogramming day 4 to 8, the medium was renewed every day.
