Pancreatic cancer end stage.

Rom J Morphol Embryol ; 58 1 : According to the literature, there are many studies on the immunohistochemical aspects of the myoepithelial cells, present in the pleomorphic adenoma of the salivary gland.

A big diversity of mono and polyclonal antibodies, such as the cytokeratins, pancreatic cancer end stage proteins and other pancreatic cancer end stage, has been used. In our study, we investigated the immunohistochemical aspect of bone morphogenetic protein 6 BMP6 marker concerning 15 cases of pleomorphic adenomas of the salivary glands.

In the immunohistochemical study, we used the paraffin blocks that served for obtaining the sections necessary for the classical histopathological processing by means of the usual stainings.

In order to underline the process of epithelial-mesenchymal transition, we also used pancreatic cancer end stage sequential immunohistochemical reactions. By the use of the BMP6 marker, we intended to evaluate the reactivity of the various tumor components in the pleomorphic adenomas of the salivary gland, for this marker, taking into consideration its possible involvement in the process of the epithelial-mesenchymal transition.

The maximum reactivity for BMP6 was recorded at the level of the normal, excretory, intratubular units, pancreatic cancer end stage the luminal cells of the proliferative ductal units, in the myxoid matrix, the cytoplasm of the myxoid stellate cells and the plasmacytoid pancreatic cancer end stage and the cytoplasm of the chondroid lacunar cells.

Some of the cells belonging to the solid, proliferative areas, some of the abluminal cells, that are part of the proliferative ductal units and certain myxoid stellate or plasmocytoid cells contain the S protein, which would indicate the existence of some processes of mesenchymal epithelial÷myoepithelial transdifferentiation in the development of this type of salivary tumor.

The BMP6 expression is specific to the serous acini salivary cells, which are the most specialized epithelial salivary gland cells.

Pancreatic cancer end stage study demonstrated that the mesenchymal epithelial÷myoepithelial potential of transdifferentiation of the luminal cells that make up the proliferative units is certified by the immunohistochemical expression of some BMP6 purely mesenchymal protein cells.
