Six years ago, researchers at the Wake Forest Institute for Regenerative Medicine used tissue-engineering techniques to grow new urethras for five young male patients from their own cells. Now, an article published in the Lancet has declared the procedure a success. Each of the boys is now in good physical health, with a new urethra that has repaired the defects previously present.
Research presented at Sunday's American Association for the Study of Liver Diseases in Boston marked a preliminary but potentially groundbreaking development in the search for the lab-engineered organs of the future. Scientists at the Institute for Regenerative Medicine at Wake Forest University Baptist Medical Center have engineered the first functioning miniature livers from human liver cells ever created in a lab setting.
