British team grows human heart valve from stem cells
The underrated stem cells and scientific research triumph again. From an article in the Guardian:
A British research team led by the world's leading heart surgeon has grown part of a human heart from stem cells for the first time. If animal trials scheduled for later this year prove successful, replacement tissue could be used in transplants for the hundreds of thousands of people suffering from heart disease within three years.
This is what free societies make possible.
