Popis: | The argyrophilic nucleolar organizer regions (AgNORs) are cellular proliferation markers, crucial for predicting the clinical course and aggressiveness of tumors. The purpose of this study was to establish an easy and practical AgNOR staining method in the cytology of dogs and cats. Air-dried cytological slides were prepared from dogs (n=14) and cats (n=12). Acetone, formalin, ethanol and methanol were tested as fixatives for AgNOR staining. Subsequently, various methods of Romanowsky-based counterstains were tested before and after AgNOR staining. Clear and strong AgNOR spots were observed with all fixatives, and post-May-Grunwald staining was the best counterstaining method. The established method showed clear AgNOR spots even in the long-term storage samples and Romanowsky-stained ones. |
