Liver sourcing

The world’s largest liver sourcing dedicated to liver cell therapy

Organ transplantation is one of the most remarkable success stories in the history of medicine. However, despite the continuing advances in medicine and technology, the need for organs and tissue remains vastly greater than the number available for transplantation.

Promethera® Biosciences LLC ensures that donated livers unsuitable for transplantation are not wasted. Instead, high quality cells are recovered from a single organ and used to treat multiple patients. Thanks to this recovery process, the gift of life can be extended to as many patients as possible.

To facilitate clinical trials, as well as commercialization and manufacturing, Promethera® has established partnerships with over 90% of the Organ Procurement Organizations (OPOs) in the US, from whom we are able to obtain non-transplantable livers. These partnerships enable us to maintain a high standard of liver cell sourcing which is essential for our therapeutic programs. To date, the Promethera® Biosciences LLC manufacturing team has processed more than 1,000 livers.

Give the Gift of Life

Without the selfless contribution made by donors and their families, these organs would not be available for life-saving transplants and vital medical research.

Transplantation gives not only hope, but also a new chance at life, to the many who suffer from organ failure. By choosing to become an organ donor, you have the power to save lives.
