In this July 13, 2012 photo, Hannah Warren, 2, poses with her parents Lee Young-mi and Darryl Warren at Seoul National University Hospital in Seoul, South Korea. Hannah received a new windpipe made from her own stem cells in a landmark operation on April 9, 2013, at Children's Hospital of Illinois in Peoria, Ill. She is the youngest patient ever to get the experimental treatment. Hannah was born without a windpipe and her doctors in South Korea expected her to die, but doctors in Illinois said Tuesday, April 30, 2013, she is recovering and likely will lead a normal life.
