Research Summary

View my most recent research

Dr. Harald C. Ott is a thoracic surgeon at the Massachusetts General Hospital and an Associate Professor in Surgery at the Harvard Medical School. He is best known for his work in whole organ regeneration. He discovered and perfected the method of stripping an organ of its own cells and then infusing the remaining scaffold with new progenitor cells (Perfusion Decellularized Matrix: Using Nature’s Platform for Engineering Bioartificial Heart. Nat Med. 2008 Feb; 14(2):213-21.). To date, his technology has been successfully applied to heart, liver, lung, kidney, and pancreas regeneration. This method of reseeding and engraftment with native cells potentially eliminates donor organ shortage and the need for life-long immunosuppression in transplant patients, and thus lays the path for effective solutions for the millions of people in need of organ repair or replacement. Harald’s background is in surgery (M.D.; University Innsbruck in Austria, 2000) and this training has been an asset for his chosen field of scientific research. The privilege to work with patients suffering from end organ failure provides both motivation and inspiration to continue his work in organ regeneration.

News & Events

  • Bioengineered Organs on Demand

    Mass General researcher Harald C. Ott may have developed a way to save lives and meet the demand for replacement organs and overcome organ rejection

  • Mass. General team creates functional, stem-cell-derived small bowel segments

    Using human induced pluripotent stem cells, a Massachusetts General Hospital research team has bioengineered functional small intestine segments that, when implanted into rats, were capable of deliver nutrients into the bloodstream.

  • Creating organs - one cell at a time

    On any given day in the Ott Lab at the MGH a number of studies are underway. Bioreactors, each with an organ inside, are hooked to complicated networks of tubes carrying special solutions into the organ’s cellular scaffolding. This is the world of Harald Ott, MD, a thoracic surgeon who leads the lab’s activities.

  • Functional heart muscle regenerated in decellularized human hearts

    MGH researchers have taken initial steps toward the creation of bioengineered human hearts using donor hearts stripped of components that would generate an immune response and cardiac muscle cells generated from induced pluripotent stem cells, which could come from a potential recipient.

  • MGH team develops transplantable bioengineered forelimb in an animal model

    A team of MGH investigators has made the first steps towards development of bioartificial replacement limbs suitable for transplantation.
