Two new studies describe the latest achievements in growing body parts in a lab and transplanting them into people, this time with nostrils and vaginas.
Windpipes, bladders, blood vessels and other structures have previously been created in part from a patient’s own cells and then implanted. Eventually, scientists hope to tackle more complicated things like lungs and kidneys with this strategy, which is aimed at avoiding rejection of transplanted organs.
The latest experiments were published online Friday in the journal Lancet.
“They both show that by using fairly simple tissue engineering techniques, you can get real tissue forming where it’s supposed to,” said Dr. Martin Birchall, of The Ear Institute at University College London, who co-authored an accompanying commentary. He said the simple methods could be useful for making other body parts, including joint cartilage, bowels and the esophagus.
One experiment involved four teenage girls in Mexico who were born without vaginas because of a rare disorder. Currently, surgeons use tissue grafts to create vaginas for such patients, but that method carries a risk of complications.
