Ga-As (808 nm) laser irradiation enhances ATP production in human neuronal cells in culture

Normal human neural progenitor (NHNP) were grown in tissue culture and were treated by Ga-As laser (808 nm, 50 mW/cm2, 0.05 J/cm2), and adenosine triphosphate (ATP) was determined at 10 min after laser application. The quantity of ATP in laser-treated cells was was significantly higher than the non-treated cells. The authors conclude that laser application to NHNP cells significantly increases ATP production which may explain the beneficial effects of low-level laser therapy (LLLT) in stroked rats.
