A look at how scientists can use embryonic stem cells to cure diseases
By: Elaine Sihera
In November 2008, history was made in Spain when scientists announced the "world's first tissue-engineered whole organ transplant using a windpipe made with the patient's own stem cells". Since then scientists all over the world have been quietly trying to emulate that achievement. Right now...
