Thursday would be the 10th Birthday for the cloned sheep known as Dolly.
Ian Wilmut was the scientist who created the cloned sheep 10 years ago.
He spent the anniversary in Madison to talk about the stem cell and regenerative medicine center being built back in Edinburgh, Scotland – where he is from.
He says stem cell research has come a long way since the inception of Dolly, – he says there’s still a long way to go but he thinks the end results will be great.
