Скачать или смотреть Peripheral Nerve Regeneration Explained: How Schwann Cells Guide Nerve Repair

Peripheral nerves possess a remarkable ability to regenerate after injury — a process made possible when the neuron’s cell body remains intact. This regeneration is driven by specialized support cells known as Schwann cells, which create a guiding pathway that directs new nerve fibers toward their original targets. These cells not only protect the damaged area but actively stimulate regrowth by forming a regenerative scaffold and releasing growth-promoting factors.

Unlike the central nervous system, where repair is limited, the peripheral nervous system demonstrates a unique capacity for healing, restoring lost sensation and motor function over time. This process plays a crucial role in recovery from nerve trauma, surgical injuries, and certain neurological conditions.

This explanation explores how peripheral nerve regeneration works, the critical role of Schwann cells, and how modern neuroscience leverages this biological mechanism to enhance nerve repair therapies and rehabilitation strategies.
