Effect of erlotinib on cell growth. (A) Dose-response curves of parental H1650, resistant subline H1650-ER1, sorted
ER1-SP and ER1-non SP cells following incubation with varying concentrations of erlotinib
for 48 hr. Each data point represents the mean of three independent experiments. The
error bars represent s.e.m. (n = 3). (B) Dose-response curves of parental H1650, sorted
H1650-SP and H1650 - non SP cells following incubation with varying concentrations
of erlotinib for 48 hr. Each data point represents the mean of six replicates. The
error bars represent S.D. (n = 6). (C) Quantification of spheroid formation by 6000
H1650-ER1 cells per well under the continuous presence of erlotinib. Each data point
represents the mean of two independent experiments. The error bars represent s.e.m.
(n = 3).
