FIGURE 5:

Low concentrations of P-Glu₄ and low light irradiation inhibit cell migration. Reduced cell migration of human breast cancer MDA-MB-231 cells after nonlethal photodynamic treatment. Cells were treated with 0 or 10 µM P-Glu₄ for 24 h and transferred to the Biocoat filters and irradiated under 13 W fluorescent light at 0.25 mW cm⁻² for 5 min (0.75 kJ m⁻²). Cells were kept in dark, left to migrate for 18 h, and stained. The images were taken using a phase contrast light microscope.
