    Abstract:
    The present study was aimed at hybridocytochemical (HCC) detection and interspecies comparison of mRNA for calcitonin (CT), calcitonin gene-related peptide (CGRP), neuropeptide Y (NPY) and somatostatin (SS) in thyroid C cells of two rodent families of wild Microtidae: pine voles and common voles and also of laboratory Muridae, Wistar rats. Studies were performed on adult males. The HCC method in situ and immunomax technique were used to detect mRNA. DNA oligonucleotide probes labeled with digoxigenin were used in the HCC method. The obtained results were compared to the results of immunocytochemical (ICC) examinations, where rabbit or mouse antibodies against human CT, SS, NPY and rat CGRP, as well as chromogranin A were performed. In the present study, HCC reaction has demonstrated the presence of mRNA for CT and CGRP in all thyroid C cells in all the species examined. However, mRNA for NPY and SS was observed in very few C cells in rat and in many more C cells in the two species of wild rodents. The distribution of the positive cells corresponded with that of ICC detected cells.
