ERK modulation during GSC differentiation: western blot analysis of pERK and ERK protein levels in GSC#1 and GSC#83 untreated or treated with PD98059 for up to 14 day of differentiation. Blots are representative of one of three separate experiments. ERK densitometry values were normalized to GAPDH used as loading control. The pERK levels were determined with respect to ERK levels. * p < 0.05 vs. undifferentiated cells (time 0); ** p < 0.001 vs. undifferentiated cells (time 0); # p < 0.001 vs. untreated cells; ç p < 0.001 vs. 7 days of differentiation; § p < 0.001 vs. 14 days of differentiation.
