The ovary is covered by a single layer of surface epithelial cells (OSE) where in vivo morphology varies from squamous to cuboidal to low columnar. OSE actively participate in cyclical ovulatory follicular rupture and the subsequent repair. OSE express a variety of peptide hormones, sex steroids, growth factors, and receptors. Many of these biological agents have been implicated in the development of epithelial ovarian carcinomas and sexually transmitted infections. Understanding aberrations in the corresponding cellular pathways is of great clinical importance as they provide useful information regarding OSE cell survival, apoptosis, transformation, and function during disease development and potential markers for disease treatment. HOSEpiC from ScienCell Research Laboratories are isolated from human ovary. HOSEpiC are cryopreserved at passage one and delivered frozen. Each vial contains >5 x 105 cells in 1 ml volume. HOSEpiC are characterized by immunofluorescence with antibodies specific to cytokeratin-18 and/or cytokeratin-19. HOSEpiC are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast, and fungi. HOSEpiC are guaranteed to further expand for 5 population doublings under the conditions provided by ScienCell Research Laboratories. Recommended Medium It is recommended to use Ovarian Epithelial Cell Medium (OEpiCM, Cat. #7311) for culturing HOSEpiC in vitro.
