Scaffold could fill a gap in stroke therapy and help damaged brains recover

Current therapeutics for treating stroke are usually about damage limitation. Now, researchers in the USA have found that injecting an amorphous and non-fibrous hydrogel containing a growth factor and another bioactive compound could aid neuronal recovery in the spaces left by the damaging effects of the stroke. This new approach might represent a first step towards an intervention that can actually treat stroke, even after the initial damage has been done.
