The present work aimed to determine the specific cellular localisation via immunohistochemistry of some factors (VEGF, Bcl, vimentin, Bax, Cyclin D1) that may be involved in the formation and/or persistence of ovarian cysts (OC) in cattle. A total of 300 ovaries were collected and evaluated by histological and immunohistochemical studies. OC showed strong positive reactions with vimentin, inhibin á subunit, VEGF and Bcl-2 antibodies in cystic walls. It is concluded that the abnormal changes in the expression of some intraovarian regulators might lead to follicle dysfunction and the cyst formation in cattle.
