Seed Acid Can Recover Damaged Nerves

Researchers from Monash University, Australia discovered a new biomaterial acid on seeds that can regrow damaged nerves in the brain and spine. Looking ahead, the invention is expected to revolutionize the treatment of damaged nerve injuries and diseases, like Parkinson's. Andrew Rodda, scientists who are members of Materials Engineering Monash researching xyloglucan , a compound derived from the acid plant. In plants, xyloglucan cells play an important role to connect with one another. Meanwhile, Andrew Rodda, has reviewed the efficacy of this biomaterial in animals that suffered damage to nerve cells.
Rodda these compounds under study can be injected in liquid form to the injured body part. Gradually, the compound was transformed into a gel when its temperature is equal to body temperature. After reaching the target, this gel acts as a support structure through which healthy cells can migrate and can be attached to the nervous system. Rodda said, as long as there are deficiencies in the healing process of damaged nerves. According to him, in a method of healing during this time, nerves can not grow back because the toxins left by former nerve to die. "Nerve cells that are sensitive, and will only grow in the most supportive environment," Rodda said as quoted medindia.net . "After injuries, new cells can not normally penetrate into the blank space after the mass death of cells. Clumps of cells at the edges, forming an impenetrable barrier. This leaves the center of the wound, which contain chemicals that can kill the nerve will grow. " According to Rodda, these compounds work by providing a temporary scaffold, in which new cells can grow and penetrate the scar. Significantly, the so-called helper cells astrocit will move toward the gel that is injected. These cells then secrete beneficial chemicals, which may help create an environment in which the nerve cells that can survive fine. The study, conducted Rodda is part of an effort to encourage regeneration of nerves in the brain and spinal cord. It builds on previous work at Monash University to understand and control the growth of nerve using biomaterial.
