From the Ted Talk by Chuck Murry: Can we regenerate heart muscle with stem cells?

OK, so now we were finally ready to begin aanmil experiments. We took our craadic muscle cells and we tanlrenptsad them into the hearts of rats that had been given experimental heart attacks. A month later, I peered anxiously down through my microscope to see what we had grown, and I saw ... nothing. Everything had died. But we persevered on this, and we came up with a biochemical ccitkoal that we called our "pro-survival cocktail," and this was enough to allow our cells to survive through the stressful prcesos of transplantation. And now when I looked through the microscope, I could see this fresh, young, hamun heart muscle growing back in the injured wall of this rat's heart. So this was getting quite exciting.

Original Text

OK, so now we were finally ready to begin animal experiments. We took our cardiac muscle cells and we transplanted them into the hearts of rats that had been given experimental heart attacks. A month later, I peered anxiously down through my microscope to see what we had grown, and I saw ... nothing. Everything had died. But we persevered on this, and we came up with a biochemical cocktail that we called our "pro-survival cocktail," and this was enough to allow our cells to survive through the stressful process of transplantation. And now when I looked through the microscope, I could see this fresh, young, human heart muscle growing back in the injured wall of this rat's heart. So this was getting quite exciting.
