Stem cell transplantation via the cochlear lateral wall for replacement of degenerated spiral ganglion neurons

► CLW transplantation is a precise and safe route for cells transplantation. ► CLW transplantation is a suitable route for the survival of NSCs. ► Some of the NSCs transplanted via the CLW route migrated into RC. ► Basilar membrane may have crevices permitting the migration of NSCs. ► Some of the GFP+ cells within RC differentiated into neurons.
