Description:
Metastatic mouse melanoma cells have a high affinity for the basement membrane and the ability to degrade it; these properties may allow tumor cells to invade the membrane and disseminate. In this study it was found that the metastatic potential of mouse melanoma cells varied when the cells were exposed in culture to fibronectin or laminin. After removal of fibronectin or exposure to laminin, the cells had an increased affinity for basement membrane collagen, were more invasive of basement membranes in vitro, and produced more lung colonies in vivo. These changes are correlated with and may be due to an increase in the laminin-binding capacity of the tumor cell surface.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Terranova, V P -- Williams, J E -- Liotta, L A -- Martin, G R -- New York, N.Y. -- Science. 1984 Nov 23;226(4677):982-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6505678" target="_blank"〉PubMed〈/a〉
