Figure 7: Quantitative real-time RT-PCR analysis of MMP-1 mRNA expression after repeated wIRA(+RL) irradiation
Human dermal fibroblasts were exposed to radiation at each cellular passage until passage 10 with a single wIRA(+RL) irradiation dose of 340 J/cm² (i.e. cumulated irradiation dose of 3400 J/cm² wIRA(+RL), corresponding to 3000 J/cm² wIRA and corresponding to 150 minutes cumulated irradiation time). Data represent the average of three experiments with the associated standard deviation of the mean.
