title: An alpha-fetoprotein-producing human gallbladder carcinoma cell line (KMG-C) shows more aggressive biologic behavior than an alpha-fetoprotein-non-producing cell line.
abstract: We have established a new human alphafetoprotein (AFP)-producing gallbladder carcinoma (GBC) cell line, termed KMG-C, from a 67-year-old Japanese male. KMG-C and its reconstituted tumors in nude mice showed the morphological features of an adenocarcinoma. Functionally, KMG-C secreted AFP, carcinoembryonic antigen, and carbohydrate antigen 19-9, as well as 7 serum proteins, including albumin and C-reactive protein. KMG-C showed more malignant biological behavior than an AFP-nonproducing GBC cell line, KMG-A, established originally from the tumor of the same patient; KMG-C had a shorter doubling time, higher tumorigenicity, and an aneuploid DNA index. Our results suggest that AFP-producing GBC cells may have more malignant biological characteristics than AFP-non-producing GBC cells in GBCs having both of these components.
