General description

Smooth Muscle Myosin, heavy chain (SMMS-1) is a cytoplasmic structural protein that is a major component of the contractile apparatus of the smooth muscle cells. SMMS-1 is also an amyoepithelium-associated protein. Anti-SMMS-1 is a mouse monoclonal antibody to smooth muscle myosin, a heavy chain that reacts with human visceral and vascular smooth muscle cells. The antibody also reacts with human myoepithelial cells. It is very helpful in identifying myoepithelial cells in benign sclerosing breast lesions and demonstrating their absence of invasive breast carcinomas.

Identification of myoepithelial cells using antibodies to cytoskeletal proteins, such as smooth muscle myosin heavy chain (SMM-HC) and calponin, can play an important role in distinguishing invasive carcinoma from its histologic mimics. However, antibodies to these proteins may also cross-react

Distinguishing low grade endometrial stromal sarcoma (ESS) from benign smooth muscle proliferations like cellular leiomyoma (CL) can be problematic; because of differing treatments and prognosis, this distinction is important. The authors tested the hypothesis that low grade ESS could be

We immunohistochemically compared benign myoepithelial tumors (adenomyoepitheliomas [AMEs]) and metaplastic matrix-producing (MMP-CA) and spindle cell (MSC-CA) carcinomas of the breast to identify helpful diagnostic markers. Normal myoepithelial cells (MECs) consistently expressed cytokeratin, alpha-smooth muscle actin (SMA), myosin, S-100, CD10, and
