The Borriello Lab studies how disseminated tumor cells (DTCs) – single cells that have spread from a primary tumor to new locations - survive in a dormant state and what causes them to “awaken” and form metastases. Since most cancer deaths result from metastatic relapse, and there are no drugs to eliminate dormant cells, our goal is to uncover how the tumor microenvironment controls dormancy and awakening.
We use advanced imaging, organotypic cultures, and in vivo models to identify the signals and cell types that regulate these processes. Our research focuses on two key questions: how the primary tumor environment programs cells to become dormant, and how stromal factors—especially those from fibroblasts—reactivate them in distant organs.
By revealing these mechanisms, we aim to develop therapies that prevent metastatic recurrence by eradicating or permanently silencing dormant tumor cells.
