Imagine collecting a burn patient's own stem cells from an unburned part of the body, placing them in a growth solution for an hour or so, then spraying that solution of human stem cells onto the raw, burned area . . . and in four days having the patient's skin looking fully back to normal.
Well, you don't have to imagine it, it's not future science fiction, it's here and now, as reported by National Geographic
Mind you, growing human flesh to put over burned areas is not new--among others, Organogenesis has been producing that kind of regenerated skin since the 1980s. Trouble is, that method takes weeks, and to protect the patient against infections, an "immediate" new skin is better. And it's here, though still experiemental.
Here's the link to the National Geographic video (via the site Big Geek Dad, which is a great source for all sorts of interesting, sometimes off-beat stuff).
