Smooth Muscle Actin, technical only
Use
Smooth muscle actin (SMA) is a key component of the cytoskeleton in smooth muscle cells and is commonly used in pathology for identifying smooth muscle tumors. SMA is expressed in smooth muscle tumors such as leiomyomas and leiomyosarcomas, as well as in myofibroblastic lesions. Technical component only. Pathologist read not included.
