Abstract
The NOCS-1 cell line was established from the left gingiva tumor in an 86-year-old Japanese man. Histopathological diagnosis of the original tumor was well-differentiated squamous cell carcinoma. NOCS-1 cells were adhesive epithelial cells with neoplastic or pleomorphic features and grew without contact inhibition. It has been subcultured 70 times during the past 26 months. From passage 3, melanin-containing cells began to be observed in the NOCS-1 cell line. The plating efficiencies were 25% and 23%, doubling times were 29 and 26 h, and saturation densities were 6.9 × 104/cm2 and 8.7 × 104/cm2, at passage 12 and 30, respectively. When NOCS-1 cells were xenotransplanted subcutaneously into SCID mice, they produced tumors that histopathologically resembled the original tumor. In addition, NOCS-1-XG cells derived from the xenotransplanted tumor were similar to NOCS-1 cells. We believe that this cell line may be a valuable tool to develop immunotherapy and chemotherapy regimens.

Establishment and characterization of human lingual squamous cell carcinoma cell lines designated Nialym derived from metastatic foci of lymph node, and Nialymx derived from transplanted tumor of Nialym cells. Hum Cell 2015; 28:143-53. [PMID: 25711304 DOI: 10.1007/s13577-014-0107-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2014] [Accepted: 12/25/2014] [Indexed: 10/23/2022]
Abstract
The squamous cell carcinoma cell lines Nialym was successfully established from metastatic foci of lymph nodes from a 48-year-old male Japanese patient with squamous cell carcinoma of the tongue. In addition, the Nialymx cell line was established from a transplanted tumor of Nialym cells in SCID mice. Nialym cells were angular, with neoplastic and pleomorphic features. Two types of Nialym cell were observed by electron microscopy; light cells and dark cells. The dark cells had a number of waved tonofilaments in the cytoplasm, while light cells showed poorly developed organelles. The population doubling times for Nialym and Nialymx cells were approximately, 46 and 42 h at the 10th passage. Nialym cells secreted 4.8 ng/ml VEGF and 5.9 ng/ml HGF, Nialymx cells also secreted 6.7 ng/ml VEGF and 4.3 ng/ml HGF at the 10th passage for 3 days of culture. Histopathological aspects of Nialym and Nialymx cell lines were similar. We believe that these cell lines are valuable tools for elucidating the mechanisms of cancer metastasis and developing immunotherapy and chemotherapy regimens.
