Stimulatory effect of low-power density He-Ne laser radiation on human fibroblasts in vitro.
Cultures of human embryonic fibroblasts in vitro were subjected to helium-neon laser single and double irradiation to investigate the influence of low-energy laser irradiation on fibroblast proliferation. Mean increase in the cell number values of irradiated cells were compared with increase values of non-irradiated control samples of fibroblasts. He-Ne laser was used as a coherent source of monochromatic radiation at 632.8 nm, and Petri-dishes with cultured fibroblasts were irradiated in way to receive radiation of energy doses of 0.5; 1; 1.5 and 2J/cm2. Single He-Ne laser irradiation exhibited a significant stimulation effect on human fibroblast proliferation in cell-culture.
