Causes for the inability of injured nerves to regenerate

Three main causes for the inability of injured nerves of the central nervous system, or CNS, to regenerate have been known to date: 1- the insufficient activation of a regeneration program in injured nerve cells that stimulates the growth of fibers, so-called axons; 2- the formation of a scar at the site of injury that is difficult for nerve fibers to penetrate; 3- an inhibitory effect of molecules in the nerve on regrowing axons.
