| Summary: | The studies on the relationship between inflammation and cancer progression have been mostly carried out with monolayer cell cultures in vitro, which can be insufficient to mimic tumor tissue. Here, we established a three-dimensional (3D) cell culture model of inflammatory microenvironment for prostate cancer cells to better evaluate the role of inflammation in prostate carcinogenesis. Formation of the cell spheroids has been achieved for LNCaP, Du145, LNCaP-104r2 prostate cancer cell lines but not for RWPE1 normal prostate epithelial cell and PC3 by using 3D Petri Dish<sup>®</sup>. We also showed that cells in inflammatory conditioned media might have a different response based on the culturing method. Overall, we are suggesting that 3D cell culture model can be a useful tool to study molecular alterations on proliferation and migration/invasion of tumor cells related to inflammation.
