Influence of low-power laser illumination on pro-inflammatory response in human endothelial cells stimulated with interleukin-1a.

Background: Regarding recent findings on the proven influence of laser light on healing and endothelial regeneration processes, this study was conducted in order to examine the influence of low-power laser illumination on the endothelial inflammatory response.

Materials And Methods: Human umbilical vein endothelial cells (HUVECs) isolated from umbilical cord, cultured in standard conditions, were harvested and passaged in 24-well plates. Laser influence on HUVEC inflammatory response was measured by stimulating them with Interleukin-1β (IL-1β) followed by laser light illumination.
