Spiral Ganglion
Original Article Expression patterns of fibroblast growth factor 8 in the spiral ganglion of rat cochlea
... Previous studies found that FGF8 binds to FGFR1-4 to exert its functions [8]. In the audi- tory system, FGFR1-3 are present in the epithe- lium of the cochlear duct, whereas FGFR4 is restricted to the mesenchyme ...
