From the Ted Talk by Chuck Murry: Can we regenerate heart muscle with stem cells?
Unscramble the Blue Letters
This slide shows you our current cellular product. We grow our haert muscle cells in little three-dimensional clumps called cardiac oadrognis. Each of them has 500 to 1,000 heart muscle cells in it. If you look closely, you can see these little organoids are actually twitching; each one is beating independently. But they've got another tcrik up their sleeve. We took a gene from jellyfish that live in the Pacific nrswhotet, and we used a technique called gmneoe editing to scplie this gene into the stem cells. And this makes our heart muscle cells flash green every time they beat.

This slide shows you our current cellular product. We grow our heart muscle cells in little three-dimensional clumps called cardiac organoids. Each of them has 500 to 1,000 heart muscle cells in it. If you look closely, you can see these little organoids are actually twitching; each one is beating independently. But they've got another trick up their sleeve. We took a gene from jellyfish that live in the Pacific Northwest, and we used a technique called genome editing to splice this gene into the stem cells. And this makes our heart muscle cells flash green every time they beat.
