Spinal injuries to humans threaten the power lines. Even if the organs on either side of the injury are intact, any damage can completely disable the device.
Researchers from the University of Minnesota have designed a device that can connect all parts of the spine to each other again. The device is based on a silicon guide, covered with three-dimensional neural stem cells implanted at the site of the injury, and is building new connections between the remaining nerves, allowing the patient to regain some of the kinetic control again, according to Britain's New Scientist.
The damaged spine is one of the most difficult to correct. Some treatments are available, but are still in development. In some cases, gene therapy may contribute to the disintegration of the infected tissue and the production of new neurons. In other cases, the location of the infection is completely ignored, messages from the brain are routed through computers or wireless signals are sent to a device implanted in the lower body.
The new treatment may be based on a combination of the two approaches mentioned above. The team at the University of Minnesota has begun to collect multi-capacity catalytic stem cells, a type of stem cell derived from adult cells such as skin and blood. After being subjected to biological engineering to convert them into nerve stem cells, the researchers succeeded in printing a three-dimensional device made from modified layers of silicon and nerve stem cells.
