Biophysical Features Of The Extracellular Matrix Direct Breast Cancer Metastasis, Alyssa Schwartz

Doctoral Dissertations

Breast cancer is plagued by two key clinical challenges; drug resistance and metastasis. Most work to date probes these events on an extremely rigid plastic surface, which recapitulates few aspects of these processes in humans. A malignant cell first resides in breast tissue, then likely travels to the bone, brain, liver, or lung, each of which has a distinct mechanical and biochemical profile. Cells transmit mechanical forces into intracellular tension and biochemical signaling events, and here we hypothesize that this mechanotransduction influences drug response, growth, and migration. To probe the impact of extracellular matrix on drug resistance, we defined a …
