Figure-3. Role of Exosomes in Sustaining Cancer Resistance Networks.
Exosome mediated export of biological material can induce a microenvironment favorable for resistance. Exosome released factor can promote (a) EMT cell morphology, resulting in stemness; (b) promote fibroblast like cell formation that causes desmoplatic reaction (stromal reaction); (c) promote immune escape mechanisms and (d) promote angiogenesis and metastasis. The miRNAs expelled by exosomes can regulate multiple signaling pathways that cumulatively promote resistant phenotype of most tumors.
