This immunohistochemical study describes the localization of progesterone receptors (PR) in the bovine ovary of 23 cows at different stages of the oestrous cycle. In primordial, primary and secondary follicles the score for PR in the follicle cells increased progressively with the maturation of the follicle. In vital tertiary follicles and cystic atretic follicles a moderate score for PR was found, while in obliterative atretic follicles the score was much lower. Scores were high in corpora hemorrhagica, low in corpora lutea and still lower in corpora albicantia. Low PR scores were also found in the tunica albuginea and surface epithelium. Cyclic variations of PR immunoreactivity were manifest in most ovarian tissues. Follicular scores for PR were high in oestrus and decreased during the following stages, whereas scores in corpora lutea cells varied according to a characteristic pattern with high levels during oestrus and metoestrus. The variations in the scores for PR in the different ovarian cell types suggest a cell-specific and cycle-dependent influence of progesterone. A negative correlation was found between the PR scores and the plasma progesterone concentration. |
