Abstract
This study proposes a procedure for the isolation and culture of oviduct epithelial cells of several species. In-vitro culture on such a feeder seems to allow full embryonic development and viability. The inner linings of Fallopian tubes from mouse, rabbit, cow and human were trypsinized and the epithelial cells were enriched with Percoll gradient. Isolated cells, obtained in high yield with good viability, were maintained in monolayer culture in B2-Menezo medium supplemented with serum, which also supports early embryonic development in vitro. The plated primary cultures reached confluence within 8 days, producting a monolayer of cohesive polygonalcells. Associated with this large epithelial call population, ciliated cells as wellas polykaryotic cells and few fibroblastic nestswere observed. After the first sub-culture, the ciliated cells disappeared and the epithelial cell monolayer grew rapidly to confluence with in 3 days and displayed contact inhibition. No epithelial cell growth could be obtained inculture in the absence of serum. The addition of oestrogens had no effect on any of the cultured oviductal epithelial cells. A sponotaneous alteration was observed in morphology and growth after several passages, the number of which depends mainly upon the species
