Reduction of brain metastasis.

<p>(A) Presence of MDA-MB-231 (BR) breast cancer cell labeled with quantum dot in the brain of mice as seen under fluorescent microscope. (B) Luminescence decay curve from mice brain starting the day of cell injection till day 10 after intra-cardiac injection of MDA-MB-231 (BR) breast cancer cells. (C) Mice brain images as analyzed by IVIS Lumina imaging system at different time points after intra-cardiac injection of MDA-MB-231 (BR) cells. (D) Average count of quantum dot labeled MDA-MB-231 (BR) tumor cells in mice brain of control and PEITC (10 µmol) treated groups. Values are represented as means±SEM. * P<0.05, statistically different when compared with control. At least 150 brain sections from each group were analyzed.
