“…Human embryonic kidney cells HEK293 [ 22 ], human lung adenocarcinoma epithelial cells A549 (DSMZ ACC107; Brauschweig, Germany), human nonsmall cell lung cancer cells H1299, A549 E1A and H1299 E1A model cells were grown in a DMEM medium (Life Technologies, UK) containing 10% fetal bovine serum (Life Technologies), 4 mM L -glutamine, 1 mM sodium pyruvate, and streptomycin/penicillin at a concentration of 100 μg/mL and 100 U/mL, respectively, at 37°C under 5% CO 2 atmosphere. Primary human limbal cells [ 24 , 25 ] were cultured on a DMEM/F12 medium (Life Technologies) containing 10% fetal bovine serum (Life Technologies), 4 mM L -glutamine, 1 mM sodium pyruvate, 10 mM HEPES, 0.4 μM insulin, 10 nM dexamethasone, and streptomycin/penicillin at a concentration of 100 μg/ mL and 100 U/mL, respectively, at 37°C under 5% CO 2 .…”
