New construction of an animal model for the orthotopic transplantation of an ovarian tumor

A new technique has successfully established the non-obese diabetic/severely combined immunodeficiency (NOD/SCID) mouse model of ovarian cancer. Under 4% chloral hydrate (0.1 mL/g dose) anesthesia, female mice were inoculated with tumor-cell suspension. The expression rate of OVCAR3 to CA125 was assessed using flow cytometry. The inoculated site was hand palpated and the signs and symptoms related to tumor growth were observed with the naked eye. The allophycocyanin (APC) indirectly labeled mouse-antihuman CA125 and fluorescein isothiocyanate (FITC)-labeled anti-mouse MHC Class I molecule (H-2K d /H-2D d )w ere observed using ac onfocal laser scanning microscope. The animal model of ovarian cancer constructed using this method can more directly reflect the characteristics of cancer cells. It provides reliable experimental results and presents a technical platform for the research of ovarian cancer stem cells.
