Here's another stem cell breakthrough—the world's first transplant of a whole human organ (a windpipe) grown from stem cells.
Not, mind you, embryonic stem cells, which involves experimenting on and killing human embryos. In fact, to date there have been no successful medical therapies emerging from embryonic stem cell experimentation. This score card, though now just over 18 months old, remains substantially accurate.
But if this report is right, the need for actual embryonic stem cells is now redundant, as other cells which share the same characteristics can now be produced in significant quantities.
