ABSTRACT
Objective To investigate the changes of myoepithelial cells in mammary atypical hyperplasia and breast cancer. Methods SP immunohistochemistry was used to detect actin expression in normal breast tissue, grade Ⅰ, Ⅱ and Ⅲ atypical hyperplasia and breast cancer. Electromicroscopy was used to observe the changes of ultrastructure of myoepithelial cells. Results Actin was only detected in myoepithelial cells of normal breast tissue and grade Ⅰand Ⅱ atypical hyperplasia. The positive expression rates of actin in grade Ⅲ atypical hyperplasia(70%) and breast cancer(90%) were significantly higher than that in grade Ⅱ atypical hyperplasia(10%), P
