Figure 2: Effects of irradiation on microbe-epithelial interactions in the second set of observations. A: Representative examples of the micrographs of the wound healing capacity of TR146 cells at 0 h and 24 h in the absence or presence of oral microbiota, both in irradiated (10 Gy) or non-irradiated (0 Gy) conditions B: Wound healing capacity of TR146 cells in the absence or presence of oral microbiota (% of open wound after 24 h, mean + SD; *p<0.05), both in irradiated (10 Gy) or non-irradiated (0 Gy) conditions. C: Concentrations of D-lactate in the co-culture medium in the absence or presence of oral microbiota, both in irradiated (10 Gy)or non-irradiated (0 Gy) conditions (mean + SD; *p<0.05).
