Abstract

The branching morphogenesis is a typical developmental process of several organs not only in vertebrates, but also in arthropods. Recent studies indicate that the reactivation of this process in pathological conditions, especially the formation of tumors, which have been best studied for the lungs and prostate. Prostate is a reproductive accessory organ present in mammals, and the study of their formation process is particularly relevant to research on the correlations between development and tumor formation, since the study of this organ enables the possibility to evaluate the interaction between endocrine and paracrine signaling pathways, as well as such is subject to a high incidence of benign tumors with senescence. The Mongolian Gerbil (Meriones unguiculatus) is promising for this type of research, since the presence of prostate cancer in females is almost ubiquitous, as well as the occurrence of benign tumors in the gland is significantly elevated compared with that of other laboratory animals. This project aims to evaluate the influence of endocrine disrupters, particularly intrauterine exposure to high doses of estradiol on the main factors of autocrine and paracrine signaling that comprise the core of epithelial-mesenchymal interactions that occur during this stage of organogenesis of the ventral lobe prostate, specifically the branching process, as well as to investigate the presence of telocytes, interstitial cells that are related to the morphophysiological organization of stroma during the process of branching and the possible influence of estrogenization on such prostatic cells. This study is particularly relevant in view of the increase in industrialized societies of xenoestrogens exposure, in which mimic the effects of body estrogens, and which have disruptive effects on prostate organogenesis, which has been linked to an increased susceptibility to tumors of prostatic origin in both men and women.
