You might recall the article about a woman who received a trachea transplant that was created from her own stem cells in Fall '08. That took place in Europe. The process for FDA clearance in the US is exceedingly cumbersome and conservative (I'm a biomedical engineer and this is a huge pain). It is a major milestone to be able to culture these cells, but this is still in the realm of science, not medicine. It may be decades before such technologies are commonly applied for medical treatments and, undoubtedly, the US will be last in line behind the other 1st world countries.
