The culture of epithelial cells from nasopharyngeal carcinoma biopsies.

Epithelial cells from nasopharyngeal carcinoma biopsies were cultured with a high percentage of success and periods of growth much longer than those previously reported. Such cultured nasopharyngeal epithelial cells, if normal, are useful for experiments with Epstein-Barr virus in relation to nasopharyngeal carcinoma, and if the epithelial cells are Epstein-Barr virus associated tumor cells, they will be most useful for investigation into the etiology of nasopharyngeal carcinoma.
