P. gingivalis W50 growth with or without the presence of estradiol (1 pg/ml, 2 pg/ml, 5 pg/ml, 10 pg/ml, 100 pg/ml, 300 pg/ml and 1000 pg/ml,) after 24 h (A) and 72 h (B). Data are presented as mean ± SEM of n = 3 independent experiments. The asterisk distinguishes statistical significance: **p < 0.01, ***p < 0.001 vs. unstimulated P. gingivalis W50.
