Fig. 6From: Primary breast cancer cell culture yields intra-tumor heterogeneous subpopulations expressing exclusive patterns of receptor tyrosine kinasesEffect of Lapatinib, Crizotinib and Imatinib on cell viability of MBCDF’s subpopulations. B2, F3, C9 (Group 2), B3, D5, C1, B6 (Group 1) were seeded as in Fig. 5. a Lapatinib was used at the following concentrations: 0, 0.001, 0.01, 0.1, 0.5 and 1 μM. b Crizotinib was added at 0, 0.01, 0.05, 0.1, 0.5, 1, 5 and 10 μM. c The following concentrations were used for Imatinib: 0, 0.01, 0.05, 0.1, 0.5, 1, 5 and 10 μM. Cell viability was evaluated as in Fig. 5. Data represent the mean ± SEM of three independent experiments seeded in triplicate. **P < 0.001Back to article page
