This is a movie of beating heart cells that were derived from a presidentially approved (H7) human embryonic stem cell line. Show me an adult stem cell population that exhibits this behavior, and I will change my opinion that embryonic stem cells are the superior source of replacement heart cells.
Thanks to the King of Nerds for recording this and posting it on YouTube. If you are prepared for the alternative lifestyle ads on The Stranger's website, you can re-view this movie in a Slog entry he made referring to the recent stem cell bill veto.
