This paper presents the establishment of a human pulmonary adenocarcinoma cell line Lu-YePa and its biological characteristics. The primary cells of Lu-YePa cell line were derived from a twenty six year old patient with poorly differentiated adenocarcinoma of the lung. After 36 days' culture, transfer was made and the cells proliferated steadily and rapidly afterwards. The doubling time was 34.6 hours. Mitotic index reached 49.5% on day 5. Chromosome number was subtriploid with the mode of 62. The large submetacentric marker chromosome was presented in 68% of cells. PAS positive granules were found in the cytoplasm. The study of concanavalin A condensation, electron microscopic observation, heterotransplantation and plating efficiency indicates that Lu-YePa cells are concordant with the human pulmonary adenocarcinoma cells in morphology and biological behavior.
