TUNEL assays of PC12 and pEGFP-Peripherin cells after NGF induction. TUNEL assay of control PC12 cells and pEGFP-Peripherin cells at 6 and 8 days of NGF induction. Only few TUNEL positive cells (arrows) could be found in the cell aggregation of control PC12 cells at the 6 and 8 days of NGF induction (A and B). (C) Some TUNEL positive cells could be found in pEGFP-Peripherin cells at 6 days of NGF induction. (D) More TUNEL positive cells could be detected in pEGFP-Peripherin cells after NGF induction for 8 days. Scale bar = 20 μm.
