Abstract
Two different types of lung cancer, a squamous cell carcinoma designated as OTUK, and an undifferentiated large cell carcinoma named as T3M-10, were investigated in vitro; both produced a moderate neutrophilia in each patient. In order to analyze this phenomenon, primary cultures were performed. Epithelial cells attached and grew in both of the cultures. The conditioned medium from both tumor cells revealed high colony-stimulating-factor (CSF) activities. From T3M-10 tumor cultures, a new CSF-producing cell line has been established. T3M-10 cells have been continuously propagated during the last 28 months and produced CSF. Chromosomal analysis revealed the cell line to be a human aneuploid one with a near-diploid mode. These results indicate that the two different types of lung cancers produce CSF, which may have stimulated granulopoiesis in vivo in the patients as well.This publication has 14 references indexed in Scilit:
