| Outline of Final Research Achievements |
The activated tumor stroma participates tumor cell growth, invasion and metastasis has been the subject of recent studies. In the present study, bone marrow-derived cells in tumor stroma were traced using the GFP bone marrow transplantation model. The result revealed that a population of GFP positive cells showed peripheralis tumor par parenchyma more than tumor center. Cancer-associated fibroblasts (CAFs) represent the major cellular component of the stroma. Bone marrow-derived cells might differentiate into inflammatory cells (tumor associated macrophage(TAMs) and endothelial cells that suggested promote tumor invasion.
