Fibroblast phenotypic transformation plays a crucial role in tumorigenesis. Tumor cell-derived exosome-mediated fibroblast has been commonly studied. However, there is still no direct evidence that the process of tumor exosomes induces fibroblasts into cancer-associated (CAFs). Herein, exosomal miRNAs were used as target to track invasion cancer normal fibroblasts, and FAP mRNA, CAF biomarker, further trace effect on recipient cells. Two DNA tetrahedral sensors developed based hybrid chain reaction signal amplification strategy fluorescence resonance energy transfer mechanism. Both showed high sensitivity good selectivity, with detection limits 4.94 6.61 pM for miR-1247-3p respectively. Moreover, two allowed us image living cell postinvasion tumor-derived exosomes, facilitating visual monitoring phenotype uncovering new perspectives metastasis development.
