本文报告应用单(多)克隆抗体,研究腮腺混合瘤、食管癌肉瘤及某些乳腺癌组织发生的初步结果。 腮腺导管上皮细胞呈角蛋白阳性,S-100蛋白阴性;肌上皮细胞S-100阳性,角蛋白阴性。腮腺混合瘤中的上皮型肿瘤细胞呈角蛋白阳性及S-100蛋白阳性,纤维形细胞及粘液等间叶成份,亦表现为S-100蛋白阳性,角蛋白阴性。表明此瘤由导管上皮和肌上 This article reports the use of single (multi)clonal antibodies to study the preliminary results of mixed tumors of the parotid gland, esophageal carcinosarcoma and certain breast cancers. The parotid ductal epithelial cells were positive for keratin protein and negative for S-100 protein; myoepithelial cells were positive for S-100 and negative for keratin. Epithelial tumor cells in the parotid gland mixed tumors showed keratin positive and S-100 protein positive, fibrillar cells and mucous mesenchymal components, also showed S-100 protein positive, keratin negative. Shows that this tumor is from the duct epithelium and muscle
