What do mice skin cells and chameleons have in common?
They can both change.
There's a new study using stem cells derived from the skin cells of mice. See this link--> mice . It turns out they are quite versatile. That's good news for science and humanity. It's been long known that adult stem cells derived from bone marrow, umbilical cord et al. are useful in medical treatments. For one thing, if you use the patient's own cells, there's not chance of rejection. Here's a link to a fact sheet in a PDF stem cell treatments .
So, I was thinking of a new comic book series called "Mouse Cells" featuring two cells with super powers living in a petri dish in a lab. They'll be like Pinky and the Brain only smaller... and less cute.
