ERBB2 and neoplasm: When comparing the primarily isolated cells with different cell lines in their transmigration rate, it is interesting that the TNBC MDA-MB-231 and MDA-MB-468 were stimulated significantly (p < 0.0167) whereas the HER2-positive SKBR3, the luminal B BT-474, the luminal A MCF-7 and T-47D, and the non-cancerous MCF-10A seemed to react to LPA similar to our healthy and tumor epithelial cells with a non-stimulated or even inhibited transmigration.
