Density of neurites in the hilus region of the cysts (A) and uterine horn (B) immunostained with VMAT2, CGRP, and TRPV1 ∼11 wk after endometriosis (ENDO) surgery. In the cysts, the density of sympathetic fibers labeled by VMAT2 was significantly greater in proestrus than estrus, whereas the density of neurites labeled with the other markers showed no significant proestrous-to-estrous differences. In proestrus (but not estrus), the density of TRPV1 neurites was less than the density of sympathetic neurites. In the uterine horn, there were no proestrous-to-estrous differences in the density of neurites labeled by any of the markers. In both stages, the density of TRPV1 neurites was signficantly less than the density of sympathetic and CGRP labeled neurites. Data are shown as means ± SE. *P < 0.05 compared with proestrus.
