CAL27 cells proliferated slowly when plated at low density in vitro. CAL27 cells plated at low density (104 cells per well) proliferated 1.5-fold over three days in the absence of serum and 1.75-fold in the presence of serum (A). FBS induced statistically significant increases in the proliferation of CAL27 cells in 96-well proliferation assays by day 3 (B) (n = 72, p < .01). Three separate, independent replications of this experiment were performed (n = 24 wells per trial).
