H2O2 induces apoptosis in DEF cells. (A) Cells were observed using phase contrast microscopy (×100). Non-H2O2-treated cells were used as controls (B). The cells were fixed and stained with DAPI. The arrows indicate apoptotic nuclei, and non-H2O2-treated cells were used as controls. (C) TUNEL assay. The arrows refer to TUNEL- positive cells, and non-H2O2-treated cells were used as controls.
