This study was intended to compare the efficacy of proliferation of HeLa cells under three different low-intensity laser irradiation (LIL), that is, 633 nm, 658 nm, and 785 nm. The time-dependent responses of proliferation of HeLa cells after the red laser irradiation and the influence of fetal bovine serum (FBS) at 1%, 2%, 5%, or 10% on the proliferation of cells were also investigated. The results indicated that the proliferation of HeLa cells in 10% FBS was in proliferation-specific homeostasis (PSH) so that it was not modulated with LIL; the proliferation in FBS at 1%, 2%, or 5% was far from PSH so that it may be wavelength dependently modulated with LIL, and the maximum proliferation promotion was conducted with LIL at 633 nm amongst the three different LIL. It was concluded the wavelength-dependent photobiomodulation of LIL on proliferation of HeLa cells may be homeostatic.

The quantitative studies with organisms of different complexity (HeLa cells, yeast organisms, E coli bacteria) to prove or disprove the stimulating action of low-intensity visible light are presented. The stimulation of DNA synthesis in HeLa cells was observed for four spectral intervals with maxima at near 400, 620, 680 and 760 nm. The red light stimulates the growth of yeast (Saccharomycodes ludwigii) and E coli in exponential growth phase. The action spectrum of monochromatic light on the growth of these organisms in the red region is very similar to that for HeLa cells.
