For a real valentine’s treat, take a look either at my site, most recent post, or the wired youtube channel and see induced pluripotent stem cells that have been directed to become cardiac muscle cells in a culture dish actually beating!! This is very, very cool!

Oh, iPS cells were once adult skin cells that were changed by adding a few new genes (genetic engineering) to revert back to an embryonic stem cell-like state. Then we convince them to become cardiac (heart) cells.

If you go to my website, in the corner is a picture of fibroblast cells (like in the dermis of your skin) in culture (on a plastic dish) forming a heart shape. For real, this student found it in the cell culture class I teach ON VALENTINE’S DAY 2006!

The background needs a little bit of editing. But, even with that, your card ia excellent in all possible ways.

Those are cool… Alas, I don’t think my wife is going to “get” any of those. My bad for marrying a “non-science-people-person”, but then nerdy women are hard to find
