Claudia Castillo, 30, suffered from tuberculosis for years.
The breakthrough allowed Claudia Castillo, 30, to receive a new section of trachea -- an airway essential for breathing -- without the risk that her body would reject the transplant.
Castillo was given the stem cell surgery, the controversial branch of medicine that some say could lead to human cloning, after suffering a severe lung collapse.

The University of Wisconsin-Madison and a Wausau, Wis., company have come up with a 37-inch, bullet and bomb-proof Humvee tire based on a polymeric web so cool looking there's no need for hub caps.
Resilient Technologies and Wisconsin-Madison's Polymer Engineering Center are creating a "non-pneumatic tire" (no air required) that will support the weight of add-on armor, survive an IED attack, and still make a 50 mph getaway. It's basically a round honeycomb wrapped with a thick, black tread.
The military wants an alternative to the current Humvee "run flat" tires, which despite the name, still need a minimal amount of air pressure to roll and can leave troops stranded after being shot or blown out.
"You see reports all the time of troops who were injured by an IED or their convoys got stranded because their tires were shot out," said Resilient's General Manager Mike Veih. "There's all sorts of armor on the vehicle, but if you're running in the theater and get your tire shot out, what have you got? You've got a bunch of armor in the middle of a field."
