Establishment and characterization of a human pancreatic cancer cell line (SUIT-2) producing carcinoembryonic antigen and carbohydrate antigen 19-9

Jpn J Cancer Res. 1987 Jan;78(1):54-62.

Abstract

A new tumor cell line (SUIT-2) derived from a metastatic liver tumor of human pancreatic carcinoma has been established in tissue culture and in nude mice, and maintained for over five years. In tissue culture, the cells grew in a monolayered sheet with a population doubling time of about 38.2 hr, and floated or piled up to form small buds above the monolayered surface in relatively confluent cultures. Chromosome counts ranged from 34 to 176 with a modal number of 45. Subcutaneous injection of cultured cells into nude mice resulted in tumor formation, histopathologically closely resembling the original neoplasm which had been classified as moderately differentiated tubular adenocarcinoma. Electron microscopic observation of the neoplastic cells revealed a characteristic pancreatic ductal epithelium. SUIT-2 cell line produces and releases at least two tumor markers, carcinoembryonic antigen and carbohydrate antigen 19-9, propagates even in serum-free medium, and metastasizes to the regional lymph nodes in nude mice xenografts.
