Ovarian Cancer May Mimic Fallopian Tube Formation

...ian cancer begins by using PAX8 to direct an adult stem cell population found on the ovarian surface to proliferate and ultimately form ovarian cancer. When this gene is turned on in an embryo, it leads to the development of fallopian tubes. When the gene is expressed in healthy adult ovarian cells that m...
