Magnetic hyperthermia diminished proliferative activity of tumor tissue compared to untreated tissue. (a) KI-67 staining of untreated and magnetic hyperthermia (MF66) treated MDA-MB-231 tumor tissue extracted 2 days and 28 days after the first magnetic hyperthermia. KI-67 positive cells stained red, nuclei stained blue. Bars: 200 μm. (b) Percentage of KI-67 positive tissue area 2 days and 28 days after the respective treatment. Bars represent categorical distribution of KI-67 positive area within the whole tissue section for all evaluated slides per group. AMF alternating magnetic field, MNP magnetic nanoparticles.
