Effect of progesterone on CGRP release from dura mater and TG in male and female rats. Displayed in the four panels are the CGRP release profiles for male dura mater (A), male TG (B), female dura mater (C), and female TG (D). In each instance, the tissues were exposed to 10 µM progesterone or vehicle, and the subsequent CGRP release is illustrated. The data, represented as mean ± SEM, (n = 5), are expressed as a percentage of the vehicle control, indicating no significant impact of progesterone on CGRP release across all conditions
