As myelin and axonal debris are removed, Schwann cells proliferate and send out numerous processes forming bands of Büngner, which represent conduits along which regenerative axons grow to try to reform their original connections. In many cases in which the profiles are small and round it is difficult to definitively separate Schwann cell processes from possible early regenerative axonal sprouts (arrow).
