Graphene nanoribbons to guide neuron growth in the injured spinal cord

James Tour and his group at Rice University, Texas, have developed a product that combines graphene nanoribbons with a biocompatible polymer gel. Dubbed Texas-PEG the product acts as a scaffold bridging the spinal cord lesion and encourages neuron growth across the gap. “Neurons grow…

Pleiotrophin treatment stimulates neuron growth in the adult CNS

Chondroitin sulfate (CS) glycosaminoglycans inhibit regeneration in the adult central nervous system (CNS). Finnish researchers have reported that HB-GAM (heparin-binding growth-associated molecule; also known as pleiotrophin), reverses the role of the CS chains, switching it from inhibiting growth to  activating the…
