Exosomes

Exosomes are not cells and do not contain DNA. Exosomes are described as vesicles containing growth factors and signaling compounds. Exosomes contain RNA and many growth factors that influence tissue repair, inflammation, and cellular behavior. Exosomes are presented as regulators of inflammation, oxidative stress, tissue repair, immune responses, and blood vessel growth. Regenerative biologics may work more by changing local environmental instructions than by directly becoming new tissue. Placental exosomes are proposed to amplify a patient's own stem cells, but this is framed as a proposed mechanism. The procedure used exosomes derived from placental stem cells without administering donor stem cells or donor DNA. Exosomes are small vesicles secreted by immature stem cells and filled with regenerative signaling material.
