An Alabama woman who lived with a pig kidney for a record 130 days had the organ removed and is back on dialysis. Towana Looney’s doctors removed the organ on April 4 after her body began rejecting it. Her doctors said Friday that she’s recovering well. While a disappointing development, that Looney’s gene-edited pig kidney lasted as long as it did is a boost to the quest for animal-to-human transplants after some earlier failures. A rigorous study of pig kidneys is set to begin this summer, an attempt to shore up the dire supply of transplantable organs.
