Research Interests:

The Schedin Lab is focused on developing breast cancer chemopreventive strategies that are targeted to specific windows of breast development. Our approach is to understand the role of tissue remodeling in mediating epithelial cell function during key windows of normal mammary gland differentiation, such as adolescent mammary gland development and the pregnancy, lactation, and involution cycle. Major areas of investigation include mammary epithelial cell / stromal interactions, pregnancy-associated breast cancer, tumor dormancy, and chemoprevention using rodent, 3-dimensional culture models and human tissue. Current Research Projects Include: 1) Determining the role of physiologic tissue remodeling in promoting metastasis in pregnancy-associated breast cancer. 2) Developing target therapies for prevention and treatment of pregnancy-associated breast cancer, and 3) Identify stromal mediators of tumor cell dormancy and metastasis by characterizing the ECM proteomes of the ‘breast-cancer protected’ and ‘at-risk’ mammary gland.
