Nerve damage: Nano framework takes stem cells piggyback
New hope for Parkinson's patients
An Australian scientist has developed a new method that could revolutionize stem cell treatment for Parkinson's disease or spinal cord injury. He created a unique three-dimensional framework, which helps stem cells achieve a faster and more effective regeneration of damaged nerves in the human body.
Used therein existing biodegradable polymer fibers David Nisbet from the Department of Materials Engineering at Monash University in Melbourne situated and worked this around so that a hitherto globally unique 3-D structures emerged.
In the process of adaptation of the fiber structure Nisbet established a combination of electrospinning and chemical treatment. The thus created scaffold can be placed in the human body at the location to be regenerated at the nerves.
"We can use the stem cells attach outside the body in the skeleton or after it has been injected into the body," Nesbit describes the possible use of nano-scaffolding. "The nerve cells grown with the framework as well as winds ivy on a trellis, forming a bridge in the brain or spinal cord. Over time, the framework decomposes and is excreted in a natural way by the body. What remains are the regenerated nerves intact. "
Faster adaptation, better growth
According to Nisbet stem cells prior methods given in the nervous system and can move freely. "Our research shows that stem cells, which are anchored to a scaffold, not only easier to grow, but also quickly adapt to their surroundings and to renew good."
Some fellow researchers have already become aware of the work of Nesbit. Scientists at the University of Toronto and at the Howard Florey Institute in Melbourne are currently conducting more tests, the preliminary results are very promising.
