A Valuable Reminder That Most Biotech is Not Controversial

This is a wonderful breakthrough in tissue engineering: Scientists took bladder and muscle cells from children with bladder disease. They then rebuilt them into a functioning bladder, which was attached to the children's existing bladders. The result is much improved bladder control without the bad side effects that can happen with current surgical techniques.

The technique might also be applied to people with other forms of bladder disease, such as cancer.
