Three human type 1 EMCA cell lines, HEC-1-A, HEC-1-B and Ishikawa, were used in this study. HEC-1-A (ATCC HTB112) and HEC-1-B (ATCC HTB113) were obtained from the American Type Culture Collection (ATCC) (Manassas, VA). Ishikawa cells were provided by Dr. Jennifer Richer (University of Colorado) [37] (link), [38] (link), [39] (link). HEC-1-A was cultured in McCoy's 5A medium (ATCC, Manassas, VA) supplemented with 10% (v/v) fetal bovine serum (FBS) (Thermo Fisher Scientific, Waltham, MA), HEC-1-B in Eagle's minimum essential medium (EMEM) (ATCC, Manassas, VA) supplemented with 10%(v/v) FBS and Ishikawa in Minimal essential medium (MEM) (Life Technologies, Carlsbad, CA) supplemented with 1% non-essential amino acids (NEAA), 6 ng/ml insulin and 5% (v/v) FBS. Antibiotics (10 units/ml of penicillin and 10 µg/ml of streptomycin) were added to all culture media. All cell lines were incubated at 37°C in a humidified atmosphere containing 5% carbon dioxide.
