Molecular biologists have focused on mutations in tumor cells in an attempt to understand cancer, but as techniques for manipulating genes and cells improve, researchers are finding that it takes more than just a cancer cell to make a tumor. New research presented in October at the American Association for Cancer Researchs International Conference on Frontiers in Cancer Prevention Research indicate that both stromal cells within and near the tumor influence cancer cell growth, as do the senescent cells within the surrounding tissue.
When Robert Weinberg, Ph.D., a lead scientist at the Whitehead Institute in Cambridge, Mass., and colleagues injected three different types of human cancer cells into mice, they found that the different cell types
