CHICAGO -- A 2-year-old girl born without a windpipe now has a new
one grown from her own stem cells, the youngest patient in the world to
benefit from the experimental treatment.
Hannah Warren has been unable to breathe, eat, drink or swallow on
her own since she was born in South Korea in 2010. Until the operation
at a central Illinois hospital, she had spent her entire life in a
hospital in Seoul. Doctors there told her parents there was no hope and
they expected her to die.
The stem cells came from Hannah's bone marrow, extracted
with a special needle inserted into her hip bone. They were seeded in a
lab onto a plastic scaffold, where it took less than a week for them to
multiply and create a new windpipe.
