Emphasis in bold. These were not embryonic stem cells, and there are many sources for stem cells that do not come from embryos.
|The landmark operation involved injecting the scaffold of a windpipe, taken from a dead donor, with stem cells from the boy before implanting it in his throat.|
The stem cells were removed from the boy's bone marrow and were ready for use just four hours later.
The cells trigger regrowth to create a normal windpipe without any of the risks of normal transplantation such as the organ being rejected by the body.
The operation took place at Great Ormond Street Hospital, in London, on Monday and the boy is breathing by himself and able to speak normally.
It is the first time a child has received an organ transplant created with stem cells and the second time that surgeons have injected the stem cells immediately before implanting the windpipe. In a previous operation the cells were allowed to grow onto the windpipe in the laboratory for some months before the organ was implanted.
