Abstract:
Objective:To establish a method of in vitro cultivation of epithelial cells of keratocystic odontogenic tumors(KCOT).Methods: Tissue block and enzyme digestion techniques were used for primary cultivation of KCOT cells.The cells were grown in keratinocyte-serum free medium(K-SFM).The biological characteristics of the cultivated keratinocytes were identified by phase microscopic observation and by immunohistochemistry of cytokeratin,vimentin,cytokeratin10 and 14.Results: KCOT keratinocytes could survive for 30-50 days in K-SFM after passing 2-4 generations.Cells were polygon and showed typical slabstone-like appearance.Immunostaining showed positive staining for cytokeratin antibody,and negative for vimentin.Conclusion: KCOT epithelial cells could be serially cultured in vitro in K-SFM by techniques suggested in this study.
