Figure 2

Effects of gefitinib on H-157 cell growth in vitro. (A)Cell proliferation was determined by assessing the mitochondrial reduction of MTT. Bars indicated means ± standard deviation of three independent experiments performed in triplicate (n = 9). Compared with untreated control cells, P > 0.05 were found in all of the treated groups. (B)Known numbers of single cells were plated into culture dishes in RPMI1640 containing 10% FBS and treated with gefitinib in several doses. Cells were then harvested by trypsinization and counted by a hemocytometer with trypan blue dye. Data points mean of triplicate samples. Data were expressed as means ± SE for three experiments. P> 0.05 vs. control group by Student's t-test was found in every treated group.
