Tattoos On Heart Could Monitor Stem Cells
Sensors Track Oxygen Levels Easily
POSTED: 2:52 pm EST December 13, 2007
Scientists say that a small tattoo placed on the heart could help
them monitor new treatments, according to researchers at the Ohio
State University.
The work looks at the idea of using stem cells to rebuild tissue
damaged by a heart attack. As they study the theory, there have been
problems monitoring progress.
But researcher Periannan Kuppusamy said tattooing tiny sensors onto
the heart could keep track.
"They give a signal -- a magnetic resonance signal -- and this signal
will give information about the oxygen concentration surrounding the
crystal," he said.
In a recent study, it showed higher oxygen levels and better function
after stem cells were transplanted into a damaged heart. The devices
could also be used on transplanted organs to make sure they are
functioning well. Kuppusamy said it could eventually be used to keep
an eye on cancer treatments, too.
However, the devices have only been used in the lab, not in people.
In any situation, oxygen is essential to help the body heal.
The next step for researchers includes building a machine large
enough for people that will read the data from the tattoo on the
heart.
