MST1R and breast cancer: In general, increased intratumoral morphological diversitycorrelated with considerable chemoresistance and a high metastasis rate of BC.We found variable expressions of epithelial (EPCAM andCDH1) and mesenchymal (ITGA5,ITGB5, CDH2, CDH11,TGFb2, ZEB1, MMP2,DCN, MST1R) markers and, thus, different EMTmanifestations in different morphological structures.
