The effect of the PI-3-kinase inhibitor, LY294002 on epidermal growth factor (EGF) disruption of differentiation. A. HC11 cells were induced to differentiate in DIP-induction media with and without EGF (10 ng/ml) and LY294002 (5 μM) for 48 hours. β-casein induction was determined via northern blot and was normalized to β-actin. B. HC11 cells were grown to confluence as stated above and induced to differentiate in DIP-induction media with and without EGF (10 ng/ml) and LY294002 (10 μM). Cells were photographed at 96 hours post-induction. The number of mammospheres per field is reported: this was determined by counting the number of mammospheres per low power field and determining the mean of five fields.
