CCN2 and breast cancer: We found, that highly plastic breast cancer cells and TNBC do not only express more CTGF but co-express CD106 (Vascular cell adhesion molecule 1) and CD51 (Integrin subunit alpha V) in a higher probability than non-invasive MCF-7 cells (Fig. 2E, F and supplementary Fig. 4; MCF-7-EMT 72.67 ± 18.21 counts CD106high CD51high vs. MCF-7; P = 0.043; n = 3; MDA-MB-231 197 ± 49 counts CD106high CD51high vs. MCF-7; P = 0.0217, n = 3).
