Human Nasal Cells in Continuous Culture.∗ I. Establishment of Two Lines of Epithelial-like Cells

Summary Two strains of epithelial-like cells derived from normal nasal mucosa have been maintained through more than 50 continuous subcultures for over a year. Both of these strains now have rapid growth rates, and exhibit the morphologic characteristics of malignant cells. The technical assistance of Miss Virginia Colville and Mrs. Juanita Ruffier is gratefully acknowledged.
