| Research Abstract |
In the tumor microenvironment, carcinoma-associated fibroblasts(CAF_s) are considered to play a critical role in the niche formation of cancer stem cells. To understand how CAF_s are generated during primary cancer progression, we investigated the biochemical characteristics of normal human prostate stromal cells(P_rSC) co-cultured with human prostate cancer(PC_a) cells in vitro. Our results have demonstrated that normal fibroblasts co-cultured with cancer cells become activated and exhibit biochemical characteristics of CAF_s in a heterogenous manner. Finally, we suggest that heterogenous induction of CAF_s-like differentiation might be strongly dependent on biochemical characteristics of adjacent cancer cells.
