Abstract
Summary Normal colonic epithelial cell cultures of mammalian origin are required to facilitate the study of both normal cellular functions as well as pathogenesis of certain (human) colonic diseases. To date, little information is available regarding the growth requirements of colonic epithelial cells in culture of eitehr animal or human origin. Such data would enable the development of a long-term culture system for these cells. In this study, we present methodology that results in the establishment of homogeneous cultures of adult rabbit colonic epithelial reproducibly, quickly, and in quantity. The epithelial nature of the cultures is unambiguously established by intermediate filament typing using antikeratin antibodies. Such culutres can now be used for a variety of functional studies as well as to investigate the growth requirements of colonic epithelial in culture.
