Could Surgeons Transplant It?"},"content":{"rendered":"
<\/div>\n

Scientists developed a way to freeze a large mammal\u2019s kidney, which could ease organ shortages in the future. First, they had to see if their method would work in a pig.<\/p>\n

On the last day of March, surgeons at Massachusetts General Hospital began an operation that they hoped might lead to a permanent change in how kidneys are transplanted in people.<\/p>\n

That morning\u2019s patient was not a person. It was a pig, lying anesthetized on a table. The pig was missing one kidney and needed an implant.<\/p>\n

While kidneys typically must be transplanted within 24 to 36 hours, the kidney going into the pig had been removed 10 days before, frozen and then thawed early that morning.<\/p>\n

Never before had anyone transplanted a frozen organ into a large animal. There was so much that could go wrong.<\/p>\n<\/div>\n<\/div>\n

\u201cI think there is about a 50 percent chance that it will work,\u201d Korkut Uygun, a professor of surgery and a leader of the team, said before the surgery. Dr. Uygun is on the scientific advisory board of Sylvatica Biotech Inc., a company that is developing freezing methods to preserve organs.<\/p>\n

But the promise from freezing and storing organs is great.<\/p>\n

There is a severe and ongoing shortage of kidneys for transplants \u2014 more than 92,000<\/a> people are on waiting lists. One reason is that the window of 24 to 36 hours is so brief that it limits the number of recipients who are good matches.<\/p>\n
