The aim of this experiment was to establish an efficient method for isolation and further culture in vitro of the normal chicken oviduct epithelial cells (COEC) for cell-based research models. Different factors were tested to optimize COEC primary culture for repeatable results: the origin of isolated cells (oviduct Infundibulum or Magnum section); the oviduct tissue dissociation procedure (mechanical scrapping or mincing), tissue digestion times (15, 30 and 45 min), the culture plates coating (colagene I, polystyrene surface or 3T3 feeder layer), the growth media (classic DMEM/Ham's F12 and defined serum-free medium, Lonza Switzerland), incubation temperature (37 °C vs 41°C) and different cell seeding numbers: 0.2M, 0.5M and 1.0M cells/well. The COEC isolated by mincing the Infundibular neck and digestion of tissue for 30 min formed cell aggregates of bright colour and gave proliferating colonies of epithelial-like character which was the best result obtained from all applied procedures in our studies. The fibroblast-like cells considered as contaminants occurred only sporadically up to day 7 of culture. Seeding about 1M cells in 1 mL of serum-free medium onto 12-well dishes gave the optimal growth of colonies resulting in 5 to 7 confluent culture wells from a single oviduct sample. Feeder layer and collagen I did not improve adhesion of the COEC to the culture vessel. Adoption of 37 °C and 41 °C did not reveal apparent differences to the condition of cultured COEC. Cell differentiation and proliferation potential depends on number and replicative capacity of isolated progenitors. The progenitors are responsible for holoclones formation and good culture growth. The percentage of colonies developed from the cells isolated from Infundibulum was greater than that of other samples in our studies. We conclude that the model of COEC primary cultures from different segments of oviduct, in particular infundibulum, should be incorporated to the range of avian cells research as this work generates questions about undocumented sources of oviduct progenitor cells.
