A migration assay revealed that those cells were able to migrate when stimulated with conditioned media from primary breast cancer cells (Figure 4A), as well as a wound healing assay established both ASCs and primary breast cancer cells, moved toward each other showing a scatter phenotype, frequently depicted as associated to c-Met activation, completely covering the free area after five days (Additional file, Figure 2D). The gene discussed is MET; the disease is breast carcinoma.
