PURPOSE This study describes the expression and distribution of arrestin, phosducin, and recoverin in the cone-dominant retina of the ground squirrel Spermophilus tridecemlineatus. METHODS mRNA expression was studied by blot hybridization of ground squirrel retinal RNA, with human and murine RNA as controls. The distribution of the gene products in the ground squirrel retina was investigated ...

The secretions of the Sertoli cell were examined with two polyvalent antisera--one prepared against proteins in rat serum and the other against testis-specific proteins in rete testis fluid. These antisera detected 12 serum and 9 testis-specific proteins in rete testis fluid. To determine the origin of these proteins, primary cultures enriched in Sertoli cells were incubated with [35S]methionin...

Myopericytoma (MPC) is a rare kind of benign neoplasm, showing derivation from perivascular myoid cells. About 115 cases have been reported in the English literature; however, most of the literature focuses on the description and classification of pathology. The case presented here is that of a 42-year-old woman with a surgical management experience of multicentric MPC in the maxillofacial regi...

Sertoli cell preparations isolated from 10-day-old rats were cultured on three different substrates: plastic, a matrix deposited by co-culture of Sertoli and peritubular myoid cells, and a reconstituted basement membrane gel from the EHS tumor. When grown on plastic, Sertoli cells formed a squamous monolayer that did not retain contaminating germ cells. Grown on the matrix deposited by Sertoli-...

Sinonasal glomangiopericytoma is defined as a low-grade malignant tumor demonstrating perivascular myoid phenotype. We report case of sinonasal having diffuse architecture with bland spindle cells arranged in short fascicles, storiform, whorled, reticular pattern, separated by vascular plexus ranging from capillaries to large patulous spaces. Immunohistochemistry required differentiate it other...

Myopericytoma (MPC) is defined as a benign mesenchymal neoplasm consisting mostly of oval spindle-shaped myoid-like cells with perivascular growth. Apart from being rare lesion in all anatomical regions the body, it extremely oral and maxillofacial region only limited number cases have been reported literature. We present here case MPC 42-year-old female patient who had painless, enlarging ante...
