In a major advance toward the development of artificial organs, bladders grown from patients' own cells in the laboratory have been successfully implanted in seven children with spina bifida and shown to function for five years or longer, researchers reported today.
The achievement, reported online in the international medical journal the Lancet, marks the first time that artificial organs more complicated than skin and bone have been implanted in humans. It brings much closer the day when scientists may be able to grow new organs for people who have lost them to disease or injury.
Clinical trials of the bladder-building process could begin later this year. The team that invented it is using the same method to grow blood vessels, kidneys, livers and other organs — some of which have already been implanted in animals.
"This work marks a new age in regenerative medicine," said Dr. Len Horovitz of Lenox Hill Hospital in New York City, who was not involved in the research.......
