Functional evidence that progenitor cells near sites of inflammation are precursors for aggressive prostate cancer

While chronic inflammation has been causally associated with several epithelial malignancies, whether it causally contributes to the development of prostate cancer has remained unclear. We recently reported that progenitor-like inflammation-associated luminal cells marked by low expression of Cluster of Differentiation 38 (CD38) can initiate human prostate cancer and predict poor outcome.
