After postdoctoral studies at the Strangeways Research Laboratory in Cambridge England, she was recruited to the faculty of the University of California, San Francisco, where she is currently Professor and Vice‐Chair of Anatomy. Her honors include the Charlotte Friend Award of the American Association for Cancer Research, the Alexander von Humboldt Research Award and the Colin Thomson Memorial Medal from the Association for International Cancer Research. Dr. Werb has been elected to the National Academy of Sciences, the Institute of Medicine, and the American Academy of Arts and Sciences. She has published more than 400 papers. Dr. Werb is recognized internationally for her fundamental discoveries about the molecular and cellular bases of extracellular matrix proteolysis by matrix metalloproteinases and their roles in the normal functioning and pathogenesis of tissues. Her studies have led to new paradigms about the role of the cellular microenvironment and intercellular communication in breast development and breast cancer. Her current research uses mouse models of breast cancer and patient‐derived breast cancer xenografts to study normal mammary development and its perturbation during tumor progression and metastasis. .

The ECM is a highly dynamic structure, constantly undergoing a remodeling process where ECM components are deposited, degraded, or otherwise modified. ECM dynamics are indispensible during restructuring of tissue architecture. ECM remodeling is an important mechanism whereby cell differentiation can be regulated, including processes such as the establishment and maintenance of stem cell niches, branch- ing morphogenesis, angiogenesis, bone remodeling, and wound repair. In contrast, abnor- mal ECM dynamics lead to deregulated cell proliferation and invasion, failure of cell death, and loss of cell differentiation, resulting in congenital defects and pathological processes including tissue fibrosis and cancer. Understanding the mechanisms of ECM remodeling and its regulation, therefore, is essential for developing new therapeutic inter- ventions for diseases and novel strategies for tissue engineering and regenerative medicine. he extracellular matrix (ECM) forms a milieu versatile and performs many functions in addi- Tsurrounding cells that reciprocally influ- tion to its structural role.
