Figure 5
Immunohistochemical assessment of inflammatory reactions in the inner ears of experimental animals. (a) Vertical slice of the cochlea from a guinea pig in Group C after immunization (); RBCs and WBCs were detected in the scala tympani (indicated by the arrow). (b) Vertical slice of the cochlea from a guinea pig in Group B after transplantation of BMSCs into the inner ear (); floccules were observed in the scala tympani (indicated by the arrow). (c) Vertical slice of the cochlea from a guinea pig in Group C after immunization (); infiltration of inflammatory cells was observed in spiral ganglion (indicated by the arrow). (d) Vertical slice of the cochlea from a guinea pig in Group A after transplantation of BMSCs into the inner ear (); the structure of the spiral ganglion was normal.
