Regrowth of nerve cell extensions surrounded by glial cells (cell nuclei are marked in blue), in the sciatic nerve of a mouse, seven days after injury (top) and 25 days after it (bottom). In mice without Silc1 (left column), the restoration is less powerful - the regrown nerve cell extensions (red) are shorter than in mice with an active Silc1 copy.
