National Geographic
Program Shows Skin Gun Sprays Healing Adult Stem Cells
Part Four of Four

It's so amazing, you have
to watch the video more than once and then check around the
Internet for verification. One headline captured the claims this
way: "Doctors have invented a revolutionary skin spray-gun that
heals severe burns within days."
Although experimental,
twelve burn victims have already been successfully treated with
a "skin gun" that takes adult stem cells from a burn victim's
own healthy skin and sprays it on to the damaged area. The skin
gun was featured last night in a program called "How to Build a
Beating Heart," which examines modern techniques of tissue
engineering on the National Geographic Channel.
The buzz generated by what
would be a revolutionary change in the way burn victims are
treated came last week with a video excerpt from Tuesday's
episode of National Geographic Channel's Explorer. It examines
the work of Dr. Jörg C. Gerlach and the McGowan Institute for
Regenerative Medicine at the University of Pittsburgh. It looks
for all the world like a somewhat more sophisticated version of
what you'd use to spray paint on your living room wall.
Gerlach tells National
Geographic Channel that the process involves "isolating stem
cells from a healthy patch of the patient's skin, putting those
cells in a water solution, and then spraying the mixture back
on," according to Stephen Adams. "After being sprayed, the
patient's wound is covered with a special dressing that provides
glucose, sugar, amino acids, antibiotics and electrolytes to the
treated area, to provide nutrition and clean the wound until the
stem cells get established." The whole process takes 90 minutes
and burns have been reportedly healed in as few as four days.
The largest flaw of
existing burns treatment is that the patient can die from
infection in the time it takes to grow new layers of skin in the
lab.
On the video excerpt, Dr
Steven Wolf, of the US Army Institute of Surgical Research in
San Antonio, Texas, says, "If we can find a way to get normal
healthy skin, as much of it as we want , within a week--that's
the holy grail of burn surgery."
