The Carpenter laboratory is interested in the role of normal tissue in promoting metastasis, the spread of tumor tissue throughout the body. Their studies focus on how this tumor cell movement may be induced by secretion of factors from the nearby normal tissue. They have learned that in the initial invasion step, normal mammary duct cells secrete a factor that increases the migratory ability of MCF-7 breast cancer cells. Currently, they investigating the nature of this mammary motility factor and have recently developed an assay to study tumor cell movement into vascular-like structures.
