Nerve regeneration of skin pathological scars promoted by mechanical tension

Scars are prone to appear at high tension parts, such as the sternum, shoulder and back, which are serious clinical problems.

Surgeons reduce scar formation through Z, W, V-Y flap variation and reduced blade tension, but its specific mechanism is still not very clear.

and colleagues from to verified that contributed to the formation of a hyperplastic scar in the back skin of rats, in conjunction with increases in both nerve density and nerve growth factor expression in the scar tissue.

These experimental findings indicate that the cutaneous nervous system plays a role in hypertrophic scar formation caused by mechanical tension, which have been published in Neural Regeneration Research (Vol. 8, No. 17, 2013).
