Peripheral Nerve Regeneration and Muscle Reinnervation
Up to this day surgeons who work with peripheral nerve injuries are struggling on getting positive recovery results. Despite improving microsurgical skills and techniques in nerve repair, the are a number of issues that remain to be the main obstacles. According to the article published in International Journal of Molecular Sciences, one of such challenges is a failure of regenerating axons to select their original endoneurial tubes. This results in misdirection of regenerating nerve fibers, that leads to improper target reinnervation. Another major issue to successfully recovery is the decay in the neuronal regenerative capacity after chronic axotomy. Over the time, chronically denervated muscle fibers still retain their satellite cells. However, the lack of full muscle fibers recovery suggests a limit to the number of the proliferative capacity of the satellite cells. The way nerves regenerate and the neuromuscular plasticity after the nerve injuries is impressive. However, a lot of questions remain unanswered to reach a goal in sufficient fine movements restoration. Read a detailed overview by the link!
