title: Preclinical humanized mouse model with ectopic ovarian tissues.
abstract: The aim of the present study was to establish human ovarian stroma within the mouse subcutaneously, in order for the resulting stroma to serve as a useful preclinical tool to study the progression of human ovarian cancer in a humanized ovarian microenvironment. Normal human ovarian tissues were subcutaneously implanted into severe combined immunodeficient (SCID) mice and then the implants were identified by immunohistochemistry. The implants became vascularized and retained their original morphology for about 4 weeks following implantation. Immunohistochemical staining for cytokeratin-7 confirmed the ovarian origin of the epithelial cells. CD34 staining demonstrated human-derived vessels. Positive estrogen receptor and partially-positive progesterone receptor staining indicated the estrogen and progesterone dependence of the implants. Only vascular pericytes expressed α-smooth muscle actin, indicating the normal ovarian origin of the xenografts. Human ovarian tissue successfully survived in SCID mice and retained its original properties. This humanized mouse model may be used as preclinical tool to investigate ovarian cancer.
