Immunohistochemical analysis of related proteins before and after NAC. Magnification: ×200. Immunohistochemistry was conducted to analyze CSC markers (CD44 and CD24), EMT markers (E-cadherin, β-catenin, vimentin, and N-cadherin) in benign breast lesions (control), and tumor tissues of Her-2 overexpression breast cancer and Her-2 overexpression breast cancer before and after NAC.
