| Outline of Final Research Achievements |
We established mouse gastric cancer cell lines that can be transplanted into C57BL/6 mice, and found that cancer associated fibroblast is of bone marrow origin. Gastric cancer peritoneal dissemination model was established with these cell lines. NIS was transfected into bone marrow derived mesenchymal stem cells (BMDC) that were already transfected with SV40T large antigen, and NIS expressing BMDC was established.
CRISPR/CAS9 system was confirmed to use for gene knock-down for the gastric cancer cell lines, and the methods for gathering BMDC around the peritoneal disseminated cancer cells were analyzed. And GFP expressing BMDC was used and the way to gather BMDC efficiently around peritoneal disseminated gastric cancer cells were established.
