The U.S. government announced plans on Monday to invest $200 million to help shorten the waiting list for patients waiting for organ transplants.

The investment, to be led by the Department of Defense, was announced at a White House summit to discuss the role of science and technology and innovation in organ transplantation.

It is designed to support technologies aimed at repairing and replacing cells and tissues, Jeff Zients, director of the White House National Economic Council told the meeting.

More than 120,000 people in the United States are on a donor waiting list, Zients said. About 80 percent of the demand is for kidneys, Zients said. End stage kidney failure costs Medicare, the federal health insurance program for the elderly and people with end stage renal disease, $34 billion a year.

That is more than 7 percent of the total Medicare budget, he added.

More than $160 million in public-private investment will go to a new Advanced Tissue Biofabrication Manufacturing Innovation Institute to help develop next-generation manufacturing techniques for cell therapies. Among other investments, $7 million will be earmarked for awards to small businesses working to advance the science of tissue preservation.

The donor registration system was built in 1968. Speakers at the summit discussed proposals for modernization, including easing the process for registering to become an organ donor via a declaration on social media.

Facebook, Tinder and Twitter are developing new tools to increase donor registration options and have a goal of achieving 1 million new registrations and social declarations by the end of 2016.
