In China, Wang’s team didn’t remove the deceased person’s own liver, instead implanting the pig liver near it.That “clouds the picture,” said Dr. Parsia Vagefi, a liver transplant surgeon at UT Southwestern Medical Center who wasn’t involved with the work. “It’s hopefully a first step but it’s still, a lot like any good research, more questions than answers.”

Wang said his team later replaced the human liver of another brain-dead person with a pig liver and is analyzing the outcome.According to media reports, another Chinese hospital last year transplanted a pig liver into a living patient after a piece of his own cancerous liver was removed but it’s unclear how that experiment turned out.The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Science and Educational Media Group and the Robert Wood Johnson Foundation.

one of the world’s largest producers and exporters of poultry, confirmed Friday the country’s firstoutbreak on a commercial farm.

The virus was found at a facility in the southern state of Rio Grande do Sul, the country’s agriculture ministry said in a statement. It said a contingency plan has been implemented “not only to eliminate the disease but also to maintain the sector’s productive capacity, ensuring supply and, consequently, food security for the population.”

The ministry said it has notified the World Organization for Animal Health, the Ministries of Health and the Environment and Brazil’s trade partners.“Our feeling is, you know, less is more,” said Montgomery, noting it’s easier to mass produce pigs with fewer gene alterations. Looney’s transplant offers a chance to compare “really how much difference those additional gene edits are making.”

In Boston, eGenesis has still another approach – a whopping 69 gene edits. In addition to 10 genetic alterations to improve human compatibility, genes linked to certain pig viruses also are inactivated.Researchers feel pressure to show if pig organs can keep people alive much longer than a few months, said eGenesis’ Curtis. If not, the question will be “do we have the right gene edits?”

The balance is choosing participants sick enough to qualify but not so sick they have no chance.“There’s a tremendous number of patients who would be very willing, very willing to do this,” said Dr. Silke Niederhaus of the University of Maryland, who isn’t involved in xenotransplant research but watches it closely.
