title: Culture of human nasal epithelial cells from nasal polyps on collagen matrix.
abstract: Epithelial cell cultures became an experimental model employed for both animal and human studies. We established a modified method of culture of human nasal epithelial cells from nasal polyps using serum-free, hormonally supplemented Ham's F-12 medium and Vitrogen 100 collagen matrix. Cells reached confluent monolayer structures in 5 to 7 days (mean time 6 +/- 0.89 days) of culture. The confluent cultures consisted of pure epithelial cells, which was confirmed by light and electron microscopy, and immunohistochemical staining with anticytokeratin antibody. The success ratio of cultures was 61.5%. The culture system described is efficient enough to provide pure epithelial cells for further functional studies.
