CHICAGOA 2-year-old girl born without a windpipe now has a new one grown from her own stem cells, the youngest patient in the world to benefit from the experimental treatment. Hannah Warren has been unable to breathe, eat, drink or swallow on her own since she was born in South Korea in 2010. Until the operation at a central Illinois hospital, she had spent her entire life in a hospital in Seoul. Doctors there told her parents there was no hope and they expected her to die. The stem cells came from Hannah's bone marrow, extracted with a special needle inserted into her hip bone. They were seeded in a lab onto a plastic scaffold, where it took less than a week for them to multiply and create a new windpipe. About the size of a 3-inch tube of penne pasta, it was implanted April 9 in a nine-hour procedure. Early signs indicate the windpipe is working, Hannah's doctors announced Tuesday, although she is still on a ventilator. They believe she will eventually be able to live at home and … [Read more...] about CBS News Logo Windpipe made from stem cells implanted in 2-year-old girl
Implant center 2
The Texas Heart Institute and St. Luke's Episcopal Hospital announced the clinical cardiovascular surgery research team, led by Dr. O.H. Frazier, has performed the world's third implantation of the AbioCor artificial heart device. "The procedure conducted Wednesday went as expected, and the patient is resting comfortably," said the hospital in a statement issued Thursday. "It couldn't have gone better," Dr. Frazier, who spent more than a decade helping develop the AbioCor replacement heart at the hospital's Texas Heart Institute, told the Houston Chronicle. "Everything looks stable now. He's not having any problems. We have some hope for him." He told the newspaper the man had been "desperately ill for a long time" with heart failure and was not a candidate for a heart transplant because of complications involving his lungs. The completely internal pump, made of plastic and titanium and weighing less than 2 pounds, is powered through the skin by an external battery pack. The … [Read more...] about CBS News Logo Another Artificial Heart Implant
Last Updated Jan 24, 2018 7:23 PM EST NEW YORK -- For the first time, researchers have used the cloning method that produced Dolly the sheep to create two healthy monkeys, bringing science an important step closer to being able to do the same with humans. Since Dolly's birth in 1996, scientists have cloned nearly two dozen kinds of mammals, including dogs, cats, pigs, cows and polo ponies, and have also created human embryos with this method.But until now, they have been unable to make babies this way in primates, the category that includes monkeys, apes and people.Couple pays almost $100,000 to clone late dog"The barrier of cloning primate species is now overcome," declared Muming Poo of the Chinese Academy of Sciences in Shanghai.He and colleagues announced their success with macaques in a paper released Wednesday by the journal Cell. The female baby monkeys, about 7 and 8 weeks old, are named Zhong Zhong and Hua Hua."It's been a long road," said one scientist who tried and failed … [Read more...] about CBS News Logo Researchers clone 2 healthy monkeys — are humans next?
In Ohio, hundreds of hopeful parents are on edge. A storage tank malfunctioned last weekend at a fertility center in Cleveland, possibly destroying more than 2,000 frozen eggs and embryos. The eggs and embryos were in a long-term storage tank at University Hospitals Fertility Center when the temperature started getting warmer. Some, like the ones belonging to Amber and Elliott Ash, had been there for years. When Elliot was diagnosed with cancer, they planned ahead so they could have a family one day. Now, they are stunned. "I'm not sure what to do next," said Elliott. "I know that when I had cancer we saved my sperm and we thought well maybe we'll go back for another retrieval and do another embryo implantation." The couple had gone through the IVF process, but after the birth of their son Ethan in 2015, Amber's medical team advised her not to carry another pregnancy. So they were planning on using another embryo through a surrogate. The hospital says they sent letters to inform … [Read more...] about Mother felt “physically ill” after hearing embryos possibly destroyed at fertility center
More than 500 families hoping to have a baby using frozen eggs or embryos might no longer have that option because of an unknown temperature fluctuation at a Ohio fertility center. University Hospitals Fertility Center's storage bank at Ahuja Medical Center in Beachwood was compromised last weekend when it "experienced unexpected temperature fluctuations" in the liquid nitrogen storage bank that holds stored eggs and embryos, said Patti DePompei, president of UH Rainbow Babies & Children’s Hospital and UH MacDonald Women’s Hospital. It's unknown if the 2,000 eggs and embryos, some stored as early as the 1980s, are still viable. DePompei said center is investigating how this happened. The hospital is reaching out to each patient individually, both through letters … [Read more...] about Fertility center tells more than 500 their frozen eggs, embryos may be damaged
