采用抗肌动蛋白(actin)、抗肌球蛋白(myosin)、抗S-100蛋白、抗胶质纤维酸性蛋白(GFAP)和抗波形蛋白(vimentin)抗体对5例腮腺多形性腺瘤中肿瘤性肌上皮细胞进行标记,发现该瘤的肿瘤性肌上皮细胞形态变化大,分布范围广,是该瘤主要增生的肿瘤细胞。在粘液样区域中,部分肿瘤性肌上皮细胞出现早期软骨样分化的特征。提示它在该瘤组织发生中起着重要作用。
Five cases of parotid pleomorphic adenoma tumor were treated with anti-actin, myosin, anti-S-100 protein, glial fibrillary acidic protein (GFAP) and vimentin antibody Myoepithelial cells were labeled and found that the tumor of the tumor myoepithelial cells morphological changes in a wide range of distribution, is the main tumor of the tumor cells. In the mucoid-like area, some of the tumorous myoepithelial cells are characterized by early cartilage-like differentiation. Suggesting that it plays an important role in the tumorigenesis.
