Stories about: laboratory-grown

The graft that keeps on giving

Tissue-engineered repairs and replacement parts aren’t just concepts out of science fiction – they promise to provide the ideal solution for thousands of children born each year with congenital anomalies or who suffer devastating injuries. A study released yesterday in The Lancet and covered on NPR reports on the latest tissue engineering advance.

Anthony Atala, a former Children’s Hospital Boston urologist and now director of the Institute for Regenerative Medicine at Wake Forest University School of Medicine, reports on five young boys in Mexico City whose damaged urethras he replaced with laboratory-grown urethras over five years ago. The patients had suffered damage to their urinary tracts from auto accidents, leaving them unable to urinate without a catheter.

In an approach he began at Children’s back in the late 1990s, Atala and his colleagues took a biopsy of bladder tissue from each boy, and expanded the cells in the laboratory until there were approximately 100 million cells
