Bovine mammary epithelial cells%Primary culture%Cells growing on cover slip%Immunohistochemistry
[Objective] To investigate the feasibility of the primary culture of bovine mammary epithelial cells in biochemical incubator. [Method] In vitro, bovine mammary epithelial cells were isolated and cultured by the tissue explant method in order to investigate the optimal culture conditions. The morphology observation and identification of the cultured cells were performed by inverted microscope observation, Giemsa staining and cytokeratin immunohistochemistry. [Result] Observed with inverted microscope, most of the bovine mammary epithelial cells were polygonal and displayed typical slabstone-like appearance. As it can be seen from cell staining results, the cell body was big and the nucleus was stained dark blue and was round or oval in shape, with clearly visible nucleoli, generally 2-4 nucleoli. The tissue-specific expression of cytokeratin 14 and cytokeratin 18 genes in mammary epithelial cells was identified by cytokeratin immunohistochemistry. [Conclusion] Primary bovine mammary epithelial cells were successfully cultured in biochemical incubator.
