In a world first in children, British and Italian doctors have transplanted a new airway (trachea) into a child and used the child’s own stem cells, in the body, to rebuild it.
The donated trachea was stripped of the donor’s old cells, down to the inert collagen. The child recipient’s bone marrow stem cells were collected, and applied to the graft in situ in the body, to rebuild the cellular component of the trachea. Thus the child’s own cells will be used to make the new airway sealed and effective.
This is the first time that this has been performed

A woman received a transplant of her own bone marrow stem cells, was able to avoid an amputation, and has started to walk again following an operation performed at Catholic University in Campobasso. This is one of the few such operations performed in Europe on the cardiovascular system using adult stem cells. The results were announced yesterday, about a month after the operation, and it is now clear that it will not be necessary to amputate the woman’s leg. “We can say that the operation was a complete success surgically,” said doctors that worked
Progress has been made against strokes thanks to stem cells. British researchers, thanks to these cells, have managed to repair brain tissue damaged by a stroke. The study, financed by the research council on biological and biotechnological sciences of the United Kingdom, was published in Nature Biomaterials. The team from the Institute of Psychiatry at the University of Nottingham, used a biodegradable polymer called Plga to build a scaffold for neural cells.
Using these they filled the cavity left by a stroke. This allows, explained Mike Modo, psychiatrist at King’s College in London and coordinator of

Kidney stem cells, according to some experts, could be able to repair kidney damage if used properly. The first researchers to identify the cells were scientists at the University of Florence, who published an article recently in the Journal of the American Society of Nephrology. Giuseppe Remuzzi, the head of the Nephrology and Dialysis division of the United Hospitals of Bergamo recently spoke about their potential in Milan at the World Nephrology Congress.
“The truth about stem cells,” explained the expert, “ is what US President Barack Obama pointed out when he announced

For patients who suffer a major heart attack, get treatment at the hospital but are left with a damaged heart, Dr. Roger Gammon of the Heart Hospital of Austin is testing a new process to reverse that damage.
Just as a Houston hospital is investigating stem cells to repair the brains of stroke patients (see yesterday’s blog), the Heart Hospital is trying out a new stem cell therapy to fix the hearts of patients who suffered their first attack.
It is one of the nation’s first hospitals to test the new therapy.
Gammon, an interventional cardiologist, is leading the clinical
