Abstract
We studied the effect of low-level laser irradiation on proliferative activity of cultured human Wharton’s jelly mesenchymal stromal sells. Cells were irradiated with a solid-state laser emitting at 650 nm; irradiation doses were 0.04, 0.4, or 4 J/cm2. Laser irradiation was performed once at the start of the cell proliferation experiment or daily throughout the experiment. Cells were cultured for 7 days. The number of viable cells was assessed using the MTT test. An increase in cell proliferative activity was detected after daily laser irradiations; the maximum stimulating effect was achieved at a dose of 0.04 J/cm2. These results substantiate medical use of lasers for expansion of cells intended for transplantation.
