چکیده انگلیسی
Tumor microenvironment modifications are related to the generation of reactive stroma and to critical events in cancer progression, such as proliferation, migration and apoptosis. In order to clarify these cellular interactions mediated by reactive stroma, we investigated the effects of cell-cell contacts, and the influence of soluble factors and extracellular matrix (ECM) secreted by Benign Prostate Hyperplasia (BPH) reactive stroma over LNCaP prostate tumor cells. Using in vitro functional assays, we demonstrated that ECM strongly stimulated LNCaP cell proliferation and migration, while inhibiting apoptosis, and inducing a deregulated expression pattern of several genes related to prostate cancer (PCa) progression. Conversely, reactive stromal cells per se and their secreted conditioned medium partially modulated these pro-tumorigenic events. These data indicate that secreted ECM in reactive stroma microenvironment contains key molecules that positively modulate important cancer hallmarks.
