[Human lung cancer cell lines in our laboratory: establishment of three large cell carcinoma cell lines and their biological characterization].
Three large cell carcinoma cell lines were established from tumors of lung cancer patients. The cell lines were named NUTLC-2, NUTLC-4 and NUTLC-5 and they were found to have the following biological characterization. 1) By chromosomal analysis, the tumor cells of two of the cell lines (NUTLC-2 and NUTLC-5) were human-origin cells. Numbers of chromosomes of these cells ranged from 52 to 59 in NUTLC-2 and from 68 to 75 in NUTLC-5, with the modal numbers of 56 and 71, respectively. 2) Primary tumor resected from the patient with lung cancer was heterotransplanted into the subcutis of a nude mouse. NUTLC-4 cell line was established in vitro from the tumor in nude mouse and the tumor cells were found to be mouse-origin cells by chromosomal analysis. Human DNA was not detected by Alu analysis. 3) The tumor cells of three cell lines could be heterotransplanted subcutaneously into nude mice. However, no natural distant metastasis in nude mouse was observed. 4) Drug sensitivity to NUTLC-2, NUTLC-4 and NUTLC-5 tumor cells differed individually according to MTT colorimetric assay, and characteristic drug sensitivity was not noted in histological types of lung cancer.
