Low-level laser irradiation modulates cell viability and creatine kinase activity in C2C12 muscle cells during the differentiation process.

What the authors concluded

An increase in cell viability was found in the laser group in comparison to the control group at all evaluation times. CK activity was significantly increased in the laser group at 72 h. Myogenin messenger RNA (mRNA) demonstrated a tendency toward an increase in the laser group, but the difference in comparison to the control group was non-significant. In conclusion, LLLI was able to modulate c
