Stem cells grown on scaffold of carbon nanotubes
6 February 2014
Scientists from the University of Surrey and the University of
California have developed a developed a technique to grow human stem
cells on a scaffold of carbon nanotubes.
These new building blocks mimic the surface of the body’s natural
support cells to act as growing medium for stem cells. This means
that cells that have previously relied on other living cells can now
be grown safely in the laboratory, free of potential contamination,
paving the way for revolutionary steps in replacing tissue after
injury or disease.
Dr Alan Dalton, senior lecturer from the Department of
Physics at the University of Surrey said: “While carbon nanotubes
have been used in the field of biomedicine for some time, their use
in human stem cell research has not previously been explored
“Synthetic stem cell scaffolding has the potential to change the
lives of thousands of people, suffering from diseases such as
Parkinson’s, diabetes and heart disease, as well as vision and
hearing loss. It could lead to cheaper transplant treatments and
could potentially one day allow us to produce whole human organs
without the need for donors.”
