| Research Abstract |
The activated fibroblasts that are found in association with cancer cells are known as cancer-associated fibroblasts (CAFs). CAFs probably promote tumor progression through specific communications with cancer cells. Methods: Control: derived from normal lung tissue and CAFs: derived from tumor in same donors were prepared from surgical tissues. The ability of fibroblasts to mediate contraction of three dimensional type I collagen gels and Fibroblasts chemotaxis were evaluated. Fibroblasts cell viability by chemoreagents was assayed. Primary fibroblasts preserved their ability to induce migration and collagen gel contraction, which was greater with CAFs than NFs and the condition media from CAFs stimulated more A549 chemotaxis. The cell viability of CAFs against CDDP showed higher than that of controls. These results showed that CAFs can maintain the phenotypic properties of myofibroblasts and be further activated the myofibroblast activity interaction with carcinoma cells.
