Another step forward for stem cells

Tuberculosis has been a scourge and continues to afflict people in the 21st century. Now comes this extraordinary report (news and science) of transplant of a stem-cell derived windpipe to a patient. This is yet another demonstration of how stem cell therapy could have a profound impact in human medicine.One of the big hopes that the scientific community has from the incoming President Obama is that he will remove obstacles to stem cell research in the USA. This report should bolster their chances.
