Grafting human neural stem cells into the spine is a promising approach to promote the recovery of function after spinal injury. Sebastian van Gorp, from the University of California San Diego, and team's work looks specifically at the effect of intraspinal grafting of human foetal spinal cord-derived neural stem cells on the recovery of neurological function in a rats with acute lumbar compression injuries.
A total of 42 three month-old female Sprague-Dawley rats, with spinal compression injuries, were allocated to one of three groups. The rats in the first group received a spinal injection with the stem cells, those in the second group received a placebo injection, while those in the third group received no injection.
Treatment effectiveness was assessed by a combination of measures, including motor and sensory function tests, presence of muscle spasticity and rigidity which causes stiffness and limits residual movement. The team also evaluated of how well the grafted cells had integrated into the rodents' spines.
Gorp and colleagues found that, compared to rats who received either the placebo injection or no injection, those who received the stem cell grafts showed a progressive and significant improvement in gait/paw placement, reduced muscle spasticity as well as improved sensitivity to both mechanical and thermal stimuli. In addition to these behavioural benefits, the researchers observed long-term improvements in the structural integrity of previously injured spinal cord segments.
The authors say: "Importantly, spinal cavity formation and muscle spasticity are frequently observed in human patients with high-speed, high-impact induced spinal cord injuries. Our findings demonstrate that human foetal spinal cord-derived neural stem cells, with an already established favorable clinical safety profile, represent a potential cell candidate for cell replacement therapy in patients with traumatic spinal injuries."Media Contact

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
