A human hepatoma cell line (Huh7,
PTA-4583) and a transformed liver cell line (Hep3B,
HB-8064) were obtained from ATCC (Manassas, VA). The cells were cultured in growth medium [
Dulbecco’s modified Eagle’s medium (DMEM; Sigma‒Aldrich: St. Louis, MO) supplemented with 10%
fetal bovine serum (FBS; GeminiBio, West Sacramento, CA), 0.1%
nonessential amino acids (Gibco-BRL), 1%
Glutamax-1 (Gibco-BRL, Grand Island, NY), and 1%
antibiotic-antimycotic solution (Thermo Fisher Scientific, Irwindale, CA)]. Human lung cancer cell lines [
Calu3 (HTB-55) and
H1299 (CRL-5803)] were obtained from ATCC. These cultured cells were maintained in Eagle’s minimum essential medium (Gibco-BRL) supplemented with 1%
Glutamax-1, 1% P/S, and 10% FBS. CD133-positive/negative Huh7, Hep3B, and
H1299 cells were isolated using CD133-conjugated magnetic microbeads (AC133,
Cell Isolation Kit, Miltenyi Biotec, Bergisch Gladbach, Germany). Two rounds of magnetic separation were performed. CD133-positive cells were cultured in growth medium as described above. The isolation quality was controlled by flow cytometry with an antibody against a different CD133 epitope (Santa Cruz Biotechnology, Dallas, TX).
