WHAT ARE EXOSOMES?
Exosomes are released from stem cells and are responsible for cell-to-cell communication and for facilitating the exchange of RNA and other important proteins between cells (e.g. fibroblasts, keratinocytes, immune cells, etc.), in addition to transferring numerous growth factors, proteins and genetic materials that have shown signs of tissue repair and improving skin cells. Exosomes contain nearly three times the amount of growth factors compared to stem cells alone. More growth factors mean a better ability to restore and revitalize target cells.
HOW CAN PATIENTS BENEFIT?
Stem cells and exosomes work together as building blocks for regeneration. Exosomes carry more than just growth factors, they carry other proteins, signaling molecules and micro-RNA that can help stimulate fibroblast growth, collagen production, elastin production, and overall skin rejuvenation.
When an exosome is released from a stem cell, it will migrate in the body. It will become attracted to cells with active inflammation and are absorbed. Once that occurs, an exosome will then release its “cargo”. These proteins, RNA and growth factors work through a complicated cell to cell interaction process to speed up regeneration processes.
