Photobiomodulation Using Different Infrared Light Sources Promotes Muscle Precursor Cells Migration and Proliferation

Photobiomodulation (PBM) has demonstrated positive effects on the muscle repair process. The aim of study was to evaluate infrared PBM using different light sources—low-level laser (LLL) at 780 nm (40 or 70 mW, 10 J/cm2, 0.4 J) LED 850 0.13 J)—and dosimetric parameters proliferation and migration cells. results showed that LLL 40 mW with same radiation exposure, led an increase in after 24 h, but no differences 48 72 h. Cells irradiated exhibited comparison control group 40mW not Moreover, cell greater 6 were found 12 h when used output power mW. Furthermore, power-LED, observed In conclusion, sources able modulate C2C12 myoblasts, only these
