The effect of OLE and TMZ on GB cell morphology. Findings of AO/PI staining showed that OLE and OLE + TMZ increased the apoptosis rate in T98G (A) and U87MG cells (B). Living cells: cells with intact green nuclei; early apoptotic cells: cells with dense green chromatin condensation areas in the nucleus; late apoptotic cells: cells with dense orange chromatin condensation areas; secondary necrotic cells: cells with intact orange nuclei

OLE: Olea europaea leaf extract, TMZ: Temozolomide, AO: Acridine orange, PI: Propidium iodide
