| Abstract: |
The aim of the present study was to investigate whether Ga-As laser irradiation can enhance adenosine triphosphate (ATP) production in normal human neural progenitor (NHNP) cells in culture. Methods: NHNP were grown in tissue culture and were treated by Ga-As laser (808 nm, 50 mW/cm2, 0.05 J/cm2), and ATP was determined at 10 min after laser application. Results: The quantity of ATP in laser-treated cells was 7513 ± 970 units, which was significantly higher (p < 0.05) than the non-treated cells, which comprised 3808 ± 539 ATP units. Conclusion: Laser application to NHNP cells significantly increases ATP production in these cells. These findings may explain the beneficial effects of low-level laser therapy (LLLT) in stroked rats. Tissue culture of NHNP cells might offer a good model to study the mechanisms associated with promotion of ATP production in the nervous system by LLLT. |
