The current report intended to inspect the photobiomodulatory effects of 632.8 nm laser on cellular parameters on artificially injured human monolayer skin fibroblast cells growing in vitro. To accomplish the specified objectives, a scratch (1-2 mm) was generated on monolayered human skin fibroblast cells. Further, cells were illuminated with a single dose of 632.8 nm (He-Ne laser; 1.5 cm beam spot; 11.8mW power; 6.68 mWcm-2) at 5 and 7 Jcm-2. Alterations due to red light laser irradiation were appraised by quantifying cytochrome c oxidase activity and Adenosine triphosphate synthesis in wounded skin fibroblast cells at various time points. Elevated ATP synthesis via cytochrome c oxidase activity was noticed in wounded cells following single exposure of 632.8 nm at 5 Jcm-2. In a nutshell, the low level laser therapy boosts numerous cellular processes in wounded fibroblast cells culminating in enhanced tissue repair.
