Long-term proliferation comparison of cells in FBS and alternative sera.

<p>The proliferation profiles of cells cultured in fetal bovine serum (FBS), calf serum (CS), iron-supplemented calf serum (ICS), FetalClone III (FC3), Cosmic calf serum (CCS), and Fetalgro (FG) were presented at passages 1, 10, 20, and 30. Cells cultured in FBS were adjusted as the baseline (1.0-fold), and the relative proliferation ratio of cells in other sera was determined accordingly. Data indicate the average value of triplicates (mean ± SD). *:p<0.01 compared with cells cultured in FBS at the same passage. N.D.: not determined for OECM-1 cells cultured in CS due to subculture termination at passage 10.
