Peter Quesenberry's Biography



Peter Quesenberry, Professor of Medicine, The Warren Alpert Medical School of Brown University

Dr Peter Quesenberry is a hematologist/oncologist with a long history of work on stem cell biology and characteristics of the stem cell, especially with regard to cell cycle transit. More recently his work has focused on extracellular vesicles and their capacity to alter cell fate and to restore injured tissue. Dr Quesenberry is the Paul Calabresi, MD Professor in Oncology and Director of Hematology/Oncology Research at the Warren Alpert Medical School of Brown University. He lists over 300 publications on PubMed. He is the American editor of the Journal of Extracellular Vesicles.

Extracellular vesicle from marrow derived mesenchymal stem cells (MSCs) have been shown to have tissue repair characteristics.  We have studied several models examining the capacity of MSC vesicles to promote tissue repair or disease reversal.  In a murine model of monocrotaline induced pulmonary hypertension we have demonstrated that MSC derived vesicles will reverse or prevent the development of pulmonary hypertension as measured by vascular remodeling and right ventricular hypertrophy.  In a similar vein we have demonstrated that MSC-derived vesicles mitigates radiation damage to murine bone marrow stem cells both in vitro and in vivo.  This latter appears to be mediated by miRNA species. Lastly, MSC-derived vesicles have been shown to reverse the malignant phenotype of both colorectal and prostate cancer cells in vitro and in vivo.

The potential therapeutic applications of possible vesicle therapy are apparent and await appropriate progress in scale up approaches for harvest of vesicle types.
