On the expression of cytokeratins and their distribution in some rabbit gland tissues.
The composition and distribution of cytokeratins were studied in a series of exocrine and endocrine glands in the rabbit, by means of anti-human monoclonal antibodies. Rabbit cytokeratins are known to be homologous to those in man, and their in situ distribution was also found to be similar. In acinic cells of the exocrine glands, only cytokeratins 8 and 18 were detected, whereas in ductal cells 1, 5, 10, 11 and 13, 19 were also present. The myoepithelial cells surrounding acini and basal duct cells were stained with the antibodies directed against cytokeratins 13 and 1, 5, 10, 11. Among the endocrine glands, a higher reactivity was observed in the thyroid gland and pancreatic islets, while pituitary and adrenal gland often remained unstained. Although the expression of cytokeratins was found to be almost homogeneous in each glandular cell type, a certain variability was observed, depending on the organ examined and the treatment carried out.
