Near-infrared irradiation stimulates cutaneous wound repair: laboratory experiments on possible mechanisms.

“In animal models, the rate of wound closure was significantly accelerated by repeated exposures.”

“The TGF-beta1 and MMP-2 content of the medium of cultured cells was significantly elevated after irradiation. The amount of MMP-2 mRNA extracted from irradiated fibroblasts was also upregulated. Negative results in thermal controls suggested that the action of the light was athermic in nature.”
