Exposure to Music Alters Cell Viability and Cell Motility of Human Nonauditory Cells in Culture
Apoptosis induced by music in MCF-7 cells. The cells were exposed to each composition as explained in Section 2 and incubated for 24, 48, or 72 h. Apoptotic cells were analyzed by flow cytometry with propidium iodide (PI) and annexin V-FITC staining. (a) Dot-plot of control cells, showing the regions used in Figures 1 and 2. (b) Percentage of cells gated in region R1 (live cells) 24 h after exposure to the compositions. (c) Percentage of cells gated in region R1 48 h after exposure to the compositions. (d) Percentage of cells gated in R1 72 h after exposure to the compositions. Data are presented as means ± SE of four independent experiments. (significant when compared with control).
