in an attempt to determine if both pleomorphic adenomas and adenoid cystic carcinomas are derived from myoepithelial cells , 23 pleomorphic adenomas , 22 adenoid cystic carcinomas , and 17 normal salivary glands were examined immunohistochemically by using monoclonal antibodies directed against actin ( huc1-1 , 1a4 ) , keratin ( ae-1 , 34 beta e 12 ) , and vimentin ( v9 ) .
