Modulation of Extracellular ATP Content of Mast Cells and DRG Neurons by Irradiation: Studies on Underlying Mechanism of Low-Level-Laser Therapy
Figure 3
Response of [Ca2+]i in HMC-1 cells induced by 657 nm and 0.28 W/cm2 laser irradiation. (a) Representative MCs before and after irradiation. Irradiation times are given in the lower right corners. The pseudocolor calibration bar on the right illustrates [Ca2+]i (in relative units). (b) Quantitative analysis from several sets of cells normalized to basal [Ca2+]i-dependent fluorescence before irradiation (=100%). Prolongation of laser irradiation enhanced fluorescence intensity in HMC-1 cells. The data represent averages ± SEM from cells. , compared to control.
