Research

Research Summary/Interests

The goal of our research program is to elucidate the mechanisms underlying cellular dormancy and activation, which has broad implications in translational applications such as mobilizing endogenous stem cells for regenerative therapies and targeting cancer therapeutics toward maintaining dormancy of disseminated tumor cells. Our research focuses on two areas: 1) activation of endogenous cardiac stem cells for heart repair, and 2) development of therapeutic strategies to prevent recurrence of metastatic breast cancer.

Regenerative Medicine: Given their capacity for self-renewal and differentiation to many cell types, stem cells have been utilized in various tissue engineering applications. One promising application of stem cell-based tissue repair is treatment of cardiovascular disease, which is responsible for 1 out of every 3 deaths in the United States. Heart failure is often caused by the irreversible loss of cardiomyocytes, and while some cell transplantation strategies have shown promise in improving cardiac function following injury, there are still many challenges involved, including survival, maturation and efficient functional integration of transplanted cells. Our group aims to develop bio-instructive scaffolds that provide the necessary mechanical and chemical signals to promote heart repair through activation of endogenous stem cell populations within the organ.

Cancer Therapeutics: Cancer mortality typically results from metastasis of the primary tumor to other organs. Though metastasis is often thought of as a late stage in tumor progression, recent studies have shown that tumor cells can widely disseminate very early, even in the pre-invasive disease stage, and can stay dormant at various sites in the body for many years before reactivating. Relapse of metastatic disease following long periods of dormancy is particularly common in breast cancer, which is a leading cause of death for women. We utilize biomaterial scaffolds to engineer metastatic niches in vivo in order to elucidate mechanisms regulating tumor cell dormancy and develop novel therapeutic strategies for controlling disseminated cells and preventing disease recurrence.
