The effect of 12-O-tetradecanoylphorbol-13-acetate on Sertoli cell morphology and cytoskeletal organization: an in vitro study by means of cryo-SEM and fluorescent techniques.

By means of cryo-scanning electron microscopy (cryo-SEM) and fluorescent techniques, evidence is provided on how 12-O-tetradecanoylphorbol-13-acetate (TPA) affects Sertoli cell morphology and F-actin and vinculin organization in vitro. In order to visualize the morphological changes, the cells were observed with cryo-SEM. F-actin was localized using rhodamine (TRI)-phalloidin and vinculin using a primary monoclonal antibody and a second TRI-conjugated antibody.
