Figure 2. Apoptosis of cell types in P. gingivalis-induced murine model. (A) Inflammatory cells, (B) fibroblasts, and (C) bone-lining cells were analyzed and quantified, then represented as percentages of apoptotic cells relative to the total cell counts in the same field of analysis by TUNEL assay. Data represent mean values ± SEM (N = 6 for the control group, N = 5 for the infected group at each time-point). *,
, and 
= statistically significant at p < 0.05, p < 0.01, and p < 0.001, respectively.
