CDH3 and neoplasm: Similarly, we captured a HER2+ and E/P-cadherin+ tumor cell cluster inside a lymph vessel (SMA+, CD31− and vimentin−) and single E-cadherin+ cells in the surrounding blood vessels (positive for CD31 and vimentin) (Fig. 6f, Supplementary Video 15 and Supplementary Table 4), in the second lymphovascular invasion model.
