Abstract:
Osteosarcoma is the most common aggressive malignancy of bone.Recent studies have discovered that exosomes can mediate intercellular transfer of biologically active molecules such as RNAs, dsDNA, and miRNAs.The specific membrane struc-ture and contents of exosomes are widely engaged into the exchange of material and information among tumor cells, which play an im-portant role in regulating the tumor microenvironment of osteosarcoma, mediating the expression of Wnt/β-catenin, TGF-βsignaling and inducing tumor cell immune escape.Exosomes derived from osteosarcoma cells with antigen-presenting cells cause significant anti-tumor effect by activating the immune response.Research on exosomes has therefore opened up a new avenue for treatment of osteosar-coma.In this article we review the role of exosomes in pathogenesis of osteosarcoma and its potential application on diagnosis and treat-ment of osteosarcoma.
