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
(…) Participation in this drive and thus registration with the National Marrow Donor Program consists of simple swabs of the cheeks using Q-tips for a DNA test. DNA information is entered into this lifesaving donor program database. If a potential donor is identified as a potential match for David or someone else in need, he/she will be contacted by the donor program to have a small amount of blood drawn for lab testing.
If that person is then confirmed as a match, he/she will be asked to provide stem cells through a simple donation procedure where blood is taken
Until recently, when a patient suffering a heart attack arrived at a hospital, doctors could open the blocked blood vessel and restore blood flow to prevent further damage. But there was nothing they could do to reverse the harm already done. That damage — scarring that can kill up to 50 percent of the heart — leaves patients with difficulty breathing, loss of energy and the inability to do things such as walk up stairs. Some patients need transplants. And some end up with hearts so weak they die.
The solution: Now doctors can repair that damage. In

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
