Proportion of trkA immuno-positive area in the follicular wall (granulosa and theca) of dominant (black bars) and subordinate follicles (white bars) collected at the time of ovariectomy (Day-groups; Day 0 = ovulation; mean ± SEM) in cattle. a Immuno-positive area of the granulosa layer (% of the total area of the granulosa). b Immuno-positive area of the theca layer (% of the total area of the theca). c Proportion of cells in the granulosa layer that were immuno-positive. d Proportion of cells in the theca layer that were immuno-positive. ^abc Values with no common superscripts are different (P < 0.05).*Difference between dominant and subordinate follicles (P < 0.05)
