A team of doctors flew to Virginia, removed the heart from a pig, put it on ice and flushed it with preservation fluid and then flew it back to Moazami. The gene-edited pigs used in these experiments were provided by Revivicor, a subsidiary of United Therapeutics, one of several biotech companies in the running to develop suitable pig organs for potential human transplant. A Warner Bros. Nationwide, fewer organs are available for transplant than are needed by patients; pig organs could expand access to transplants and allow doctors to broaden who is eligible for such procedures.
