Spray on skin

Spray on skin will help burn victims recover. Not as science-fictiony as it sounds, it does involve the application of skin cells by aerosol, but over a lattice constructed of skin grafts.

The advantage of it is that the repairs don't require the patient to give up equal amounts of skin from somewhere else, letting the cultured skin cells that are sprayed on do most of the work. The treatment is thought to be quite a bit less expensive than traditional treatments, which I imagine will be of considerable benefit in terms of letting your average Joe or Sally get it.
