Proteomic analysis of H460 and MCF7 cell lines grown in 2D and 3D culture conditions

In this study we analyzed the proteomic profiles of H460, and MCF7 3D tumor spheroids grown either in standard medium (3D_SM), or in FBSlow conditions (3D_FBSlow) and compared them to their relative 2D cultures (2D). Standard medium consisted of DMEM/F-12 supplemented with 0.5% Glucose, 2.5mM L-Glutamine, 2% B-27, 5μg/ml Heparin, 20μg/ml Insulin, 20ng/ml EGF, 20ng/ml Recombinant Human bFGF, 0.1% Bovine Serum Albumin (BSA) and 1% (v/v) of penicillin/streptomycin 100U/ml. FBSlow medium consisted of customized nutrient-restricted RPMI or DMEM culture media supplemented with only 2% FBS.
