Tumour-derived exosomes (TEX) can promote the transformation of normal cells by transferring growth factors and oncogenes [e.g. Epithelial Growth Factor (EGFR) and Transforming Growth Factor (TGF-β)], as well as non-coding RNAs that can regulate the expression of tumour suppressor genes [14, 16]. This evidence concerns the gene EGFR and neoplasm.
