Isolation, cell culture and immunocytochemical characterization of oviduct epithelial cells of the cow

in Reproduction

Summary. Incubation of cow oviducts flushed with 0·1 mg collagenase/ml, for 90 min helped to dislodge large numbers of ciliated and secretory cells. About 90–95% of the isolated epithelial cells were viable. The epithelial cells suspended in DMEM:F-12 + 10% serum attached to the plastic culture dish in 18–20 h after seeding. The ciliated cells which attached to the plastic dish lost their cilia after 4–5 days in culture. The attached cells, which proliferated to form a confluent monolayer 8–10 days after seeding in a 35-mm dish, could be subcultured at least 3 successive times. Some cell aggregates which did not attach to the culture dish proliferated into floating balls of cells. The ciliated cells in the unattached floating colonies maintained the ciliary movement for 9–10 days in the same culture medium. The primary cultures of the ciliated and the secretory cells maintained most of the histoarchitecture observed in intact epithelium. The secretory cells maintained their secretory activity of specific proteins in culture as indicated by immunocytology. The cultured cells contained keratin, a specific cytoskeletal component of epithelial cells.
