ABSTRACT
BACKGROUND/AIM:
The lethal characteristic of pancreatic cancer is metastasis which is recalcitrant to currently-used chemotherapy. Our aim was to understand metastasis at the cellular level. We previously reported that multi-nucleate cells or spindle cells were more prominent in pancreatic cancer metastasis than in the primary tumor. In the present report, we investigated four representative human pancreatic cell lines for differences in cell morphology between the primary tumor and various metastatic organ targets for each cell line. MATERIALS ANDMETHODS:
Human pancreatic cancer cell lines AsPC-1, Panc-1, KP2 and KP3 were used. Pancreatic cancer cells were injected into spleen of nude mice resulting in experimental metastasis to various organs which were observed at the cellular level when the organs were placed into culture.RESULTS:
AsPC-1 and KP2 pancreatic cells formed many experimental liver metastases, in contrast to Panc-1 and KP3. Lung metastasis was only observed for AsPC-1. In the cultures established from the primary and metastatic tumors, multi-nucleate cells were found to be more prominent in the metastasis of the pancreatic cell lines with frequent metastasis, AsPC-1 and KP2. Spindle-like cells were observed prominently in AsPC-1 lung metastasis.CONCLUSION:
Human pancreatic cancer cell lines have differential metastatic characteristics with regard to target organs and cell-morphology changes. Multi-nucleate and spindle cells may play an important role in pancreatic cancer metastasis to the liver and lung, respectively.Palabras clave
