CHICAGO – A 2-year-old girl who was implanted with a windpipe grown from her own stem cells has died, three months after she became the youngest person to receive the experimental treatment.

Hannah Warren died Saturday at Children’s Hospital of Illinois in Peoria, hospital spokeswoman Shelli Dankoff said. Dr. Rick Pearl, one of three surgeons involved in the operation, told the Associated Press that Hannah died of lung complications following a second surgery, but that the new windpipe “worked very well” until the end.

Her family asked for privacy, but expressed their sorrow in a fundraising blog updated Sunday: “She is a pioneer in stem-cell technology and her impact will reach all corners of our beautiful Earth. Her new trachea was performing well, but her lungs went from fairly good, to weak, to poor.”

Hannah’s treatment was part of an ongoing scientific effort to develop lab-grown tissues and organs. Similar methods have been used to grow bladders and urethras, and last year a girl in Sweden got a lab-made vein using her own stem cells and a cadaver vein.

In Hannah’s case, the stem cells came from her bone marrow. They were seeded in a lab onto a plastic scaffold, where it took a few days for them to multiply and create a new windpipe, which was implanted April 9.

Hannah was born in South Korea and traveled to Illinois for the surgery. Hannah had lived in a Seoul hospital all her short life before flying to the U.S. and her lungs weren’t strong, said Pearl, who is surgeon-in-chief at Children’s Hospital. She required a second surgery June 11 for a leak in her esophagus. Lung complications followed.

The girl’s family and her caregivers believe the knowledge gained from her surgery will benefit other patients.

“We learned the trachea transplant worked. That’s very important and nobody should lose sight of that,” Pearl said.

Hannah would have been 3 years old on Aug. 22.

“We will forever miss her infectious personality and miraculous strength and spirit,” her family wrote on their blog.
