Abstract

It has been found that low power lasers in the visible and near IR cause biostimulation of injured tissues. We therefore studied the effect of a light source in the visible, HeNe, 633nm, and near IR 780nm, on fibroblast proliferation. We found that at certain low energy doses there is an enhancement in their proliferation. As intracellular Ca²⁺ movements play a vital role in cell proliferation, we measured intracellular Ca²⁺ concentration variations in irradiated fibroblasts by using a dynamic fibroblast proliferation also change intracellular Ca²⁺ concentration in these cells.
