In our laboratory we aim to study the mechanisms responsible for female fertility and the development of the follicle in the ovary. The ovarian follicle contains the oocyte and follicular cells, which produce the female sex hormones estradiol and progesterone. If the oocyte is fertilized, it is implanted in the uterine endometrium and ends in a successful birth. The principal function of the corpus luteum is the production of progesterone, an essential hormone for the preparation of the uterine endometrium where the embryo is implanted and develops. On the other hand, we investigate aspects related to the development and progression of ovarian cancer and the interaction of cancer cells with their tumor microenvironment. In this way, we aim to find solutions for cases in which the fertility of women is altered, and therapeutic strategies in patients with ovarian cancer.
