Abstract Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy with poor prognosis due to its highly metastatic profile. Intercellular communication between cancer and stromal cells via extracellular vesicles (EVs) is crucial for the premetastatic microenvironment preparation leading to tumour metastasis. This study shows that under the influence of bioactive peptides derived from the extracellular matrix microenvironment, illustrated here by the AG‐9 elastin‐derived peptide (EDP), PDAC cells secrete more tumour‐derived EVs. Compared to PDAC‐derived EVs, tumour‐derived EVs resulting from AG‐9 treatment (PDAC AG‐9‐derived EVs) significantly stimulated cell proliferation. At constant amount, tumour‐derived EVs were similarly taken up by PDAC and HMEC‐1 cells. Tumour‐derived EVs stimulated cell proliferation, migration, proteinase secretion, and angiogenesis. Bioluminescence imaging allowed tumour‐derived EV/FLuc+ tracking in vivo in a PDAC mouse model. The biodistribution of PDAC AG‐9‐derived EVs was different to PDAC‐derived EVs. Our results demonstrate that the microenvironment, through EDP release, may not only influence the genesis of EVs but may also affect tumour progression (tumour growth and angiogenesis), and metastatic homing by modifying the in vivo biodistribution of tumour‐derived EVs. They are potential candidates for targeted drug delivery and modulation of tumour progression, and they constitute a new generation of therapeutic tools, merging oncology and genic therapy.
