| Outline of Final Research Achievements |
Carcinoma-associated fibroblasts (CAFs) are activated fibroblasts that support the proliferation and invasion of adjacent cancer cells. In the tumor microenvironment, CAFs communicate not only with cancer cells but also surrounding stromal cells. In this study, we performed in vitro co-culture experiments using commercially available normal human prostate stromal cells PrSC and primary cultures of human prostate fibroblasts (pcPrFs) derived from prostate cancer patients. In PrSC, protein productions of TGFb1, IL-6, and VEGF were significantly increased by co-culturing with pcPrFs. Similarly, those of IL-6 and VEGF in pcPrFs were significantly increased by co-culturing with PrSC. In PrSC, mRNA expressions of growth factor were significantly increased by co-culturing with pcPrFs. Those of growth factor in pcPrFs were significantly increased by co-culturing with PrSC. Here our results demonstrated that interactions between PrSC and pcPrFs showed quite heterogeneous.
