Paper Abstract

Meningioma cell cultures were prepared from frozen cell samples in 96 wells culture plates. Semiconductor light sources (LED) in seven different wavelength ranges were used to illuminate the wells, three different irradiation doses were selected per LED. Control cultures using three different concentrations of FBS were processed for comparison. Cell proliferation, viability, and cytotoxicity were measured every 24 hours for 6 days, using the XTT colorimetric assay (RocheR). None of the irradiated cultures exhibit cytotoxicity; but some of them exhibit proliferation inhibition. The larger proliferation was detected at a 0.05J/cm2 dose, for all LEDs; but for the orange and violet LEDs generated the bigger proliferation rate was measured. Results show the improvement of meningioma cell proliferation using illumination in some given wavelength ranges.
