From the Ted Talk by Chuck Murry: Can we regenerate heart muscle with stem cells?
Unscramble the Blue Letters
What does this mean? It means the cells are alive, they're well, they're beating, and they've managed to connect with one another so that they're beating in synchrony. But it gets even more interesting than this. If you look at that tracing that's along the bottom, that's the electrocardiogram from the guinea pig's own heart. And if you line up the fihlsnag with the heartbeat that's shown on the bottom, what you can see is there's a perfect one-to-one correspondence. In other words, the guinea pig's nraatul pacemaker is calling the shots, and the hamun heart muscle clles are following in lskcoetp like good soldiers.

What does this mean? It means the cells are alive, they're well, they're beating, and they've managed to connect with one another so that they're beating in synchrony. But it gets even more interesting than this. If you look at that tracing that's along the bottom, that's the electrocardiogram from the guinea pig's own heart. And if you line up the flashing with the heartbeat that's shown on the bottom, what you can see is there's a perfect one-to-one correspondence. In other words, the guinea pig's natural pacemaker is calling the shots, and the human heart muscle cells are following in lockstep like good soldiers.
