Control of Cell Function by Photobiomodulation

Photobiomodulation involves the use of low-power lasers or lights to activate intracellular or extracellular chromophores to stimulate cellular signaling. Over the past 50 decades, research has demonstrated that laser or light therapy has the potential to improve wound healing and reduce pain and inflammation. In recent years, the term photobiomodulation has become widely recognized. This chapter describes the mechanisms of action of photobiomodulation at the cellular level, including some examples of our data showing that photobiomodulation enhances cell differentiation.
