• 8-10 week old mice injected with an adenovirus expressing cre recombinase (AdCre) into the right ovarian bursa develop ovarian carcinoma with 100% penetrance within 6 weeks of AdCre injection
• tumors show similarity to human ovarian endometrioid adenocarcinoma, with formation of distinct glands and occasional foci of squamous differentiation

homeostasis/metabolism
• 76% of ovarian bursa AdCre injected mice develop hemorrhagic ascites and 21% develop overt peritoneal dissemination of tumors

reproductive system
• 8-10 week old mice injected with an adenovirus expressing cre recombinase (AdCre) into the right ovarian bursa develop ovarian carcinoma with 100% penetrance within 6 weeks of AdCre injection
• tumors show similarity to human ovarian endometrioid adenocarcinoma, with formation of distinct glands and occasional foci of squamous differentiation
