Given how much we already know about human biology, it is astounding what we are still learning about our own bodies.  Take, for example, skin. We have been using skin cells to do all kinds of amazing things, like make other organs and cells, but up until now, we never saw them walk.

But apparently, that's what research from Washington State University is showing us (though to be honest, it looks a little more like shuffling to me) The study, published in FASEB Journal, shows that skins cells will alter the proteins holding them in place and move to repair a wound.


Normal skin cells are held in place by contact with surrounding cells and proteins that bind them to underlying connective tissue. The researchers saw how cells in the epidermis will dissolve the glue that binds them and reuse some of the proteins to move to seal a wound site. The cells will also grow more cells to form new, healed skin.

While the process behind it will still need further study, being able to manipulate the phenomenon will mean better wound healing, especially for the elderly and diabetics.
