End organ failure is the leading health care challenge in the Western World. Nearly six million Americans suffer from heart failure with about 550,000 new cases diagnosed annually; 25 million Americans suffer from chronic obstructive pulmonary disease (COPD) with an estimated 12 million new yearly diagnoses; and 530,000 Americans suffer from end stage renal disease.

Currently, organ transplantation is the only potentially curative therapy available. However, its outcomes are limited by shortage of donor organs and the side effects of harsh immunosuppressive treatments designed to prevent the body from rejecting the organ.

The Ott Laboratory is investigating tissue engineered organs as an alternative to donor transplantation. The goal is to create various whole organs that are derived from a patient’s own cells, and transplanting them into patients, avoiding the need for a donor. This process could address the donor shortages and eliminate the need for immunosuppressive drugs.

The Ott Laboratory developed and first reported a novel technique to isolate the whole organ extracellular matrix (ECM) scaffolds by a process called perfusion decellularization.

In preliminary studies, these ECM scaffolds supported engraftment of specialized cells to form viable and functional hearts, lungs, kidneys, pancreas, and composite tissue that could be transplanted and function in the body.
