Know thy neighbor: stromal cells can contribute oncogenic signals

Curr Opin Genet Dev. 2001 Feb;11(1):54-9. doi: 10.1016/s0959-437x(00)00156-8.

Abstract

Although the stroma within carcinogenic lesions is known to be supportive and responsive to tumors, new data increasingly show that the stroma also has a more active, oncogenic role in tumorigenesis. Stromal cells and their products can transform adjacent tissues in the absence of pre-existing tumor cells by inciting phenotypic and genomic changes in the epithelial cells. The oncogenic action of distinctive stromal components has been demonstrated through a variety of approaches, which provide clues about the cellular pathways involved.
