Research Abstract

7, 12-Dimethylbenz(a)anthracene (DMBA)induced murine pancreatic cancer model was established, which mimicked undifferentiated human pancreatic cancer. Bone marrow derived cells were incorporated in tumor tissue in this model. Almost half of cells in the tumor tissue were derived from bone marrow, which were spindle like morphology resembling cancer cells in this model. By the immunohistochemical analysis, CK19, α-smooth muscle actin (α-SMA)and vimentin were negative in these cells, whereas vascular endothelial marker CD31 and macrophage marker CD68 were positive in a part of these cells. Because the bone marrow derived cells were found in abundant in the invasive edge of cancer, it is possible that these cells play an important role to facilitate the invasion of the cancer cells into the host pancreas.
