FIG. 5.

Aromatase (CYP19A1) activity of endometrial stromal fibroblasts (hESFs) from women with (n = 4) and without endometriosis (n = 4) treated in vitro with or without 8-Br-cAMP for 96 h, with subsequent incubation with 12.5 nM of [1β-³H]androstenedione for 16 h. Results are expressed as picomoles of [³H]H₂O formed in 16 h/mg total protein. Cells from each patient were run in triplicates. *Significance accepted at P < 0.05 (one-way ANOVA with the Tukey-Kramer Multiple comparisons test). Error bars represent ± SEM.
