...Anthony Atala, of Harvard Medical School and Children’s Hospital, is one of a team of researchers whose work harvesting rabbit penises in laboratory incubators has provided hope for a small but growing population of parents: those whose children are born with ambiguous genitalia...
...born with ambiguous genitalia is “a life-changing event,” according to Atala. “For us it’s very serious stuff,” he says. “We’re the ones who have to face the parents when the baby is born. It’s very devastating. You can’t even tell the family in the first 48 hours whether the baby is a boy or a girl...
...That part was then attached to the rabbits’ deficient penile tissue, and eventually the entire organ functioned with almost perfect normalcy. “They had the same activity, they had the same frequency, they had the same ability to penetrate, copulate and ejaculate,” Atala says...
...Harvard team can successfully extend their research from rabbits to humans—and Atala believes that this is possible—the potentially disastrous psychological effects of being forced into a gender that is not one’s own could be avoided. For now, though, Atala says he is taking the research one step at a time. “It’s a very complex issue,” he says. “That’s why we are targeting this kind of therapy, just so that we can have other options...
LIVERS AND BLADDERS. Anthony Atala, a surgeon who makes bladders at Boston's Children's Hospital, has taken muscle cells from the outside of dog bladders and lining cells from the inside and grown them in his lab. The cells, fed the proper growth-prompting chemicals, happily go forth and multiply. "In six weeks we have enough cells to cover a football field," Atala says. He placed a few muscle cells on the surface of a small polymer sphere and some lining cells on the inside. When he inserted the sphere in a dog's urinary system, the artificial bladder...
