An injectable gel that could help patients with traumatic brain injury (TBI) may be ready for human testing in three years' time.
This is the prediction of assistant professor of bioengineering Ning Zhang from the Clemson University.
In laboratory studies with adult rats, the biomaterial product has shown it might be used as a first step towards brain tissue regeneration by reconstructing the vascular network at the site of the damage.
"We have seen an increase in brain injuries due to combat, but our strategy can also potentially be applied to head injuries caused by car accidents, falls and gunshot wounds," stated Ms Zhang.
She added the study is the first of its kind to show such a recovery in the animal model of TBI and is one of the only investigations to use a tissue-engineering approach to try and repair the lesion cavity.
Ms Zhang presented the findings of her research at the Military Research Forum in Kansas City yesterday (September 2nd).
The event is being held to discuss how to prevent and treat TBI for soldiers fighting in Iraq and Afghanistan.
