Modulation of Extracellular ATP Content of Mast Cells and DRG Neurons by Irradiation: Studies on Underlying Mechanism of Low-Level-Laser Therapy

Figure 1

Extracellular ATP content of HMC-1 cells in response to 657 nm and 0.28 W/cm2 laser irradiation. Relative changes of extracellular ATP level of HMC-1 cells induced by laser irradiation averaged for respective irradiation times of all samples. The data represent averages ± SEM from independent experiments. , compared to the preirradiation value.
