Exosomes

Exosomes contain proteins such as growth factors. enzymes, receptors, transcription factors and matrix proteins that govern cell structure, function and signaling. They also contain messenger RNA (mRNA), the blueprint for protein production, and micro RNA (miRNA), an important intracellular signaling mediator. Having the same type of membrane as their parent cells, Exosomes protect these exosomal proteins and miRNA from degradation until they are delivered to the target cell.

When Exosomes deliver their contents to target cells, exosomal proteins can have direct effects on intracellular processes and signaling. E signaling. Exosomal mRNA may be translated by the target cell to produce numerous copies of the regenerative protein. Exosomes miRNA influences target cell protein production by interfering with specific endogenous protein production. Exosomes signaling can also alter target cell exosome loading for cascading effects and a more sustained effect than the type of proteins in PRP or amniotic fluid alone could achieve.
