Two cell strains from human pancreatic cancer taken surgically were transplanted to the pancreas of pureline BALB/C-nu/nu nude mice and 9 generations of PTNMP-1 and 6 generations of PTNMP-2 were obtained. Biological properties were studied. It yielded a transplant success rate of 95% - 100% and large amount of CEA. Analysis of the karyotype confermed that they retained the karyotype of human cancer cells. Some lymphatic and blood stream metastasis and invasion could be found in the nude mice orthotopically transplanted with tumour, showing that the transplanted tumour had characteristics identical with the donor tumour.
