It all comes down to that important signal sent out by fibroblasts. It’s not a perfect process, but it works, and scientists are trying to find ways to improve it. These cords show axons the way, guiding them across the injured site. ![]() Schwann cells, following their orders, break up into cords (or clumps) and find their way out as a group. They enlist the help of fibroblasts, a type of cell that plays a role in wound healing.įibroblasts send out a signal telling Schwann cells to get to work. These cells can’t do all the work by themselves. These cells are wrapped around axons, and when there’s an injury, they get to work rebuilding the bridge. It requires both ends to find each other through damaged tissue.Ī special type of cells, called Schwann cells, play an important role in this process. Regrowing and reforming this connection is hard work. If a peripheral nerve gets cut, all of the axons below the injury start to degenerate. ![]() Their nucleus is in the spinal cord, and axons extend out to send nerve messages all the way down the leg (or other areas of the body). Peripheral nerves – the nerves that connect our organs and limbs to the central nervous system – have an amazing ability to regenerate themselves after an injury. Let’s look at how nerves heal themselves, how long damaged nerves take to heal, and what you can do to speed up the process. But here’s the good news: Healing damaged nerves is possible. It can be painful (or the opposite – completely numb), and it’s an ongoing battle. Most people with diabetes (70%) have some nerve damage. An estimated 20 million Americans have some form of peripheral nerve damage. ![]()
