Remarkably, cell lines derived from normal breast epithelial cells, MCF10A, MCF10F and MCF12A, showed very high expression levels of FN1, SERPINE1, ZFHX1B, SNAI2, TGFB1, TWIST1 and VIM and low values for CDH1 and ELF3, which is comparable to expression data from cell lines in the ‘Fibroblastic-Tumour’ subcluster. Here, TGFB1 is linked to neoplasm.
