Establishment and characterization of immortalized bovine endometrial epithelial cells.
Bottom Line: Immortalized bovine EECs were established by transfecting retroviral vectors encoding human papillomavirus (HPV) E6 and E7, and human telomerase reverse transcriptase (hTERT) genes.In addition, imEECs have maintained the features as EECs, exhibiting oxytocin (OT) and interferon tau (IFNT) responsiveness.Therefore, these imEECs, even after numbers of passages, could be used as an in vitro model to investigate cellular and molecular mechanisms, by which the uterine epithelium responds to IFNT stimulation, the event required for the maternal recognition of pregnancy in the bovine species.

Mentions: Immunofluorescence studies were then performed. Primary EECs exhibited positive signals for cytokeratin and negative for vimentin, while imEECs cells stained positive for both cytokeratin and vimentin (Fig. 4).
