CAF-derived EVs mediate cancer therapy resistance through complex mechanisms. CAF-derived EVs can deliver multiple cargoes to tumour cells, including miRNAs, lncRNAs, circRNAs and proteins. They can mediate the resistance to chemotherapy, targeted therapy, radiotherapy, and immunotherapy through multiple biological mechanisms, such as regulation of autophagy, EMT, and cancer stemness, metabolism, angiogenesis, DNA repair, immune infiltration, cell cycle, transcription and oncogenic signalling pathways
