Since lymph node stromal cells remain largely uncharacterized with respect to cell surface markers and function, their role in regulating the growth and invasion of disseminated cancer cells, including breast carcinoma has, to date, been virtually unexplored. In the present study, we asked whether peripheral lymph node cells could modulate the growth of breast carcinoma cells and, thereby, contribute to the progression of the metastatic process. Primary cultures of rat peripheral lymph node stromal cells were obtained by limiting dilution and two sublines, STA4 and STB12, with breast carcinoma growth-promoting activities were isolated. Immunocytochemistry performed on these cells revealed that they express vimentin, S-100 and fibronectin, but neither cytokeratin nor von Willebrand factor indicating that they are stromal and dendritic in origin. Several functional studies were performed using media conditioned by STA4 and STB12 cells. (Abstract shortened by UMI.)
