Figure 5: Quantitative real-time RT-PCR analysis of MMP-1 mRNA expression after single wIRA(+RL) or UV-A(+BL) irradiation at 37°C
Human dermal fibroblast cells were exposed to wIRA(+RL) with an irradiation dose of 680 and 1360 J/cm² (corresponding to 600 and 1200 J/cm² wIRA and corresponding to 30 and 60 minutes irradiation) or UV-A(+BL) irradiation (50 J/cm², corresponding to 30 minutes irradiation) performed on a 37°C temperature regulated water bath. Data represent the average of three experiments with the associated standard deviation of the mean.
