From the Ted Talk by Chuck Murry: Can we regenerate heart muscle with stem cells?
Unscramble the Blue Letters
The next question was: Will this new msulce beat in synchrony with the rest of the heart? So to answer that, we returned to the cells that had that jellyfish gene in them. We used these cells essentially like a space probe that we could lnucah into a foreign environment and then have that flashing reprot back to us about their biological activity. What you're seeing here is a zoomed-in view, a black-and-white image of a guinea pig's heart that was injured and then received three grafts of our human cairdac muscle. So you see those sort of dgaoallniy running white liens. Each of those is a needle track that contains a couple of million human cardiac muscle cells in it. And when I start the video, you can see what we saw when we looked through the microscope. Our cells are flashing, and they're flashing in synchrony, back through the walls of the ierjund heart.

The next question was: Will this new muscle beat in synchrony with the rest of the heart? So to answer that, we returned to the cells that had that jellyfish gene in them. We used these cells essentially like a space probe that we could launch into a foreign environment and then have that flashing report back to us about their biological activity. What you're seeing here is a zoomed-in view, a black-and-white image of a guinea pig's heart that was injured and then received three grafts of our human cardiac muscle. So you see those sort of diagonally running white lines. Each of those is a needle track that contains a couple of million human cardiac muscle cells in it. And when I start the video, you can see what we saw when we looked through the microscope. Our cells are flashing, and they're flashing in synchrony, back through the walls of the injured heart.
