Low-Level Laser Irradiation (InGaAlP-660 nm) Increases Fibroblast Cell Proliferation and Reduces Cell Death in a Dose-Dependent Manner

In cell culture, primary fibroblasts treated with laser at 660 nm were shown to increase proliferation and decrease cell death at an irradiance of 2.5 W/cm2 and a fluence of 150 J/cm2.
