CD276 and endometrioid adenocarcinoma: The diagnostic potential of CD276 in the ovarian tumor was assessed for which mouse vascular endothelial cells (MS1) were first stably transfected with the human CD276 gene to produce MS1CD276 cells and then coinjected to mice with human OC 2008 cells (endometrioid adenocarcinoma) to induce xenograft tumors (the experimental group).
