Abstract
Different techniques for culturing respiratory epithelial cells have been developed to overcome the limitations of studies on in vivo and on bioptic material. Traditionally, culture systems are divided into organ cultures, explant cultures and dissociated cell cultures. The first two contain both epithelial and non-epithelial cells. However, in monolayer cultures of dissociated cells only epithelial cells are present, the effects observed are caused by a pure epithelial responses. The purpose of this study is to establish primary culture method of human nasal epithelium (HNEC) by monolayer culture of dissociated cells to evaluate the role of the epithelial cells in the allergic and non-allergic nasal inflammatory reactions. HNEC was prepared by primary culture method of monolayer culture of dissociated cells from human inferior nasal turbinate mucosa of septal deviation patients. Primary cultured cells were characterized by indirect immunofluorescence assay and transmission electron microscopy. The immunoreactivities of cytokeratin-pan and cytokeratin No. 8 were observed in cultured HNEC. However, the immnoreactivities of vimentin and von Willebrand factor were not observed in cultured HNEC. The tonofilaments and desmosome were observed in cultured HNEC. The cultured epithelial cells were identified to be pure nasal epithelial cells. The monolayer culture of dissociated cells could successfully be employed for further study to investigate the role of the epithelial cells in allergic or non-allergic nasal inflammatory diseases.
Key Words: Human nasal epithelial cells(HNEC), Monolayer culture of dissociated cells
