by University at Buffalo The images above show neuromuscular junctions in a control group (left images), a group with a sciatic injury (middle images), and a group with a sciatic injury where NANOG was expressed. The green shows presynaptic axons and synaptic vesicles; the red shows postsynaptic acetylcholine receptors (AChRs); and the yellow shows regions of...

A new approach to peripheral nerve injury?
In animal models of a totally crushed peripheral nerve, the damaged axons are broken down, allowing healthy ones to regrow. But humans rarely suffer complete axonal damage. Instead, axons tend to be partially damaged, causing neuropathic pain — a difficult-to-treat, chronic pain associated with nerve trauma, chemotherapy and diabetes. A new study in Cell, led...

3D-printed nerve stem cells could help patch up spinal cord injuries
Spinal injuries can be like downed power lines – even if everything on either side of the injury is perfectly functional, the break can effectively shut down the whole system. Now, researchers at the University of Minnesota have designed a device that could link everything back together again. A silicone guide, covered in 3D-printed neuronal stem cells,...
