Detection and localization of heat shock protein 70 in the normal guinea pig cochlea.

Normal guinea pig cochlear sections were treated with an antibody against heat shock protein (HSP70). HSP70-like immunoreactivity was observed in Claudius' cells and in the interdental cells of the spiral limbus. In the organ of Corti, immunoreactivity was confined to pillar cells, as well as Hensen's and Deiters' cells.
