In the untreated OC explants, HSP70 localizes to limbal fibrocytes and interdental cells. Shown are the representative laser confocal micrographs of untreated OC cultures stained with a monoclonal antibody against HSP70 followed by FITC-conjugated secondary antibody. (A) the entire explant (basal part); (B) HSP70-positive fibrocytes in spiral limbus; (C) interdental limbal cells.
