Induction of hypodiploidic DNA contents and Annexin V positivity in human glioblastoma cells. Cultured human glioblastoma cells, GBM8401 (a) and U-87MG (b), were treated with either CM or mycelial fermentation (MF) for 24 h at the dose indicated, followed by propidium iodide (PI) staining and subsequent flow cytometric detection. The representative sub-G1 histogram profiles from three independent experiments are shown. (c) GBM8401 cells were treated with MF for indicated duration and subjected to Annexin V-FITC and PI detection by using flow cytometry. The percentage of sub-G1 and Annexin V-positive fractions in total cell populations is measured as mean±S.D. NC, negative control
