The adult ovarian surface epithelium has already been proposed as a source of stem cells and germinal cells. Present studies have confirmed the occurrence of stem cells in ovaries of adult mammals, including humans. This paper briefly describes ovarian stem cells, mesenchymal stem cells, putative stem cells and ovarian germ cells. With their differentiation potential, these cells constitute a very interesting research field as stem cells are used in a few medical disciplines and their application in fertility treatment is probably only a matter of time.
