Abstract: Our previous study found that the activity of PCa-MSCs, which could stimulate the cell proliferation of RM-1, was significantly different compared to BMMSCs. Our results indicated that it could be mediated in part by growth factors/chemokines, which were involved in the different activity between two kinds of MSCs (PCa-MSCs and BMMSCs). Normal MSCs (BMMSCs) were isolated from the femur, tibia of the normal mice; prostate tumor MSCs (PCa-MSCs) were obtained from the mice implanted with prostate tumor. Analysis of the expression of SDF-1, CXCR4, VEGF, bFGF and vWF of two kinds of MSCs were examined by ELISA, Realtime-PCR and Western blotting. The expressions of SDF-1 and CXCR4 in PCa-MSCs were higher compared to BMMSCs. Expressions of bFGF and vWF were higher in PCa-MSCs yet the difference did not reach statistical significance. The expression of VEGF was significantly higher in PCa-MSCs. Our data showed that activity of PCa-MSCs was significantly improved compared with BMMSCs, which seemed to have an intrinsic, cell-specific capacity localized to PCa. It could be induced by some factors or chemokines such as SDF-1, CXCR4, and VEGF. The possible role of PCa-MSCs in the process of PCa development needed further clarification.
