A: Glial shNf-1/shTp53 control and sgAtg7 cells were serum starved 4 hr then stimulated with 20 ng/mL TexasRed-EGF (TxRed-EGF) for 30 min. Scale bar: 10 μm. B: Quantification of TxRed-EGF puncta per cell, relative to the number taken up by control cells (in A). Data information: Statistical analyses were performed on at least 3 independent experiments, where error bars represent SEM and p values represent a two-tailed Student's t test: NS p>0.05, * p<0.05, *** p<0.001.
