Organ Reengineering Group

Organ transplantation remains the only solution to many diseases, including organ failure. Approximately 120,000 patients are currently on the organ waiting list in the U.S. alone. Most will perish while waiting for a donor organ.

Despite the apparent shortage, the number of donors available for organ recovery is in the hundreds of thousands. The problem is that most of these organs are suboptimal, and without treatment must be precluded from transplantation.

Our group aims to develop novel approaches to render these organs transplantable and ultimately eliminate the donor organ shortage. Our research focuses on the development of an organ revitalization platform, the basis of which is extracorporeal machine perfusion enabling multiple dynamic preservation modalities.

Ongoing research projects:

  • Revitalization and transplantation of cadaveric (1hr warm ischemic) rat, pig, and eventually human livers after recovery with room temperature perfusion
  • Machine perfusion of organs that are extensively injured beyond recovery for transplantation in order to enhance the recovery of cells from organs
  • Subzero nonfreezing (supercooling) for extended storage durations, with the intent to ultimately bank organs
  • New perfusion methods to decellularize non-salvageable cadaveric organs to create whole-organ scaffolds for tissue engineering
