LONDON, England (AP) -- Doctors have given a woman a new windpipe 
with tissue grown from her own stem cells, eliminating the need for 
anti-rejection drugs.

Claudia Castillo, 30, suffered from tuberculosis for years.

"This technique has great promise," said Dr. Eric Genden, who did a 
similar transplant in 2005 at Mount Sinai Hospital in New York. That 
operation used both donor and recipient tissue. Only a handful of 
windpipe, or trachea, transplants have ever been done.

If successful, the procedure could become a new standard of 
treatment, said Genden, who was not involved in the research.

The results were published online Wednesday in the medical journal, The Lancet.

The transplant was given to Claudia Castillo, a 30-year-old Colombian 
mother of two living in Barcelona, who suffered from tuberculosis for 
years. After a severe collapse of her left lung in March, Castillo 
needed regular hospital visits to clear her airways and was unable to 
take care of her children.

Doctors initially thought the only solution was to remove the entire 
left lung. But Dr. Paolo Macchiarini, head of thoracic surgery at 
Barcelona's Hospital Clinic, proposed a windpipe transplant instead.

Once doctors had a donor windpipe, scientists at Italy's University 
of Padua stripped off all its cells, leaving only a tube of connective tissue.

Meanwhile, doctors at the University of Bristol took a sample of 
Castillo's bone marrow from her hip. They used the bone marrow's stem 
cells to create millions of cartilage and tissue cells to cover and 
line the windpipe.

Experts at the University of Milan then used a device to put the new 
cartilage and tissue onto the windpipe. The new windpipe was 
transplanted into Castillo in June.

"They have created a functional, biological structure that can't be 
rejected," said Dr. Allan Kirk of the American Society of 
Transplantation. "It's an important advance, but constructing an 
entire organ is still a long way off."

So far, Castillo has shown no signs of rejection and is not taking 
any immune-suppressing drugs, which can cause side effects like high 
blood pressure, kidney failure and cancer.

"I was scared at the beginning," Castillo said in a press statement. 
"I am now enjoying life and am very happy that my illness has been cured."

Her doctors say she is now able to take care of her children, and can 
walk reasonable distances without becoming out of breath. Castillo 
even reported dancing all night at a club in Barcelona recently.

Genden said that Castillo's progress needed to be closely monitored. 
"Time will tell if this lasts," he said. Genden added that it can 
take up to three years to know if the windpipe's cartilage structure 
is solid and won't fall apart.

People who might benefit include children born with defective 
airways, people with scars or tumors in their windpipes, and those 
with collapsed windpipes.

The technique might even be adapted to other organs like the bowel, 
bladder, or reproductive tract, Birchall said.

"Patients engineering their own tissues is the key way forward," said 
Dr. Patrick Warnke, a surgeon at the University of Kiel in Germany. 
Warnke is also growing patients' tissues from stem cells for transplants.

Warnke predicted that doctors might one day be able to produce organs 
in the laboratory from patients' own stem cells. "That is still years 
away, but we need pioneering approaches like this to solve the 
problem," he said.

Prayer for Unborn Life:
O GOD OF LIFE AND LOVE, You have given us the gift to participate 
with You to bring new life into the world.  But, all too often, the 
mother's womb, which should be a nursery of life, becomes instead a 
place of it's destruction.

Help us to remove this evil and ensure respect for all life made in 
Your image and likeness, called to fulfill its promise on this earth,
and destined to find a home with you for all eternity.

We ask this through Jesus Christ, Our Lord, Our God, Our Savior, and Our ALL.
Amen.
