In previous studies we have shown that epidermal growth factor (EGF) at concentrations between 50 and 100 ng/mL induced apoptosis in wild-type SK-N-SH neuroblastoma cells. We hypothesize that this apoptotic event separates EGF-induced neuroblastoma cell growth into a biphasic concentration-dependent
