Stem cell derived exosomes have been shown to be the source of healing in stem cell treatments. The process for which stem cell products heal the body is as follows:
An injured tissue releases chemical markers signaling their damage > a stem cell absorbs these markers and creates the appropriate components for healing the tissue > the stem cell packages these components into a vesicle called an exosome > the exosome goes to the site of injured tissue and attaches > the exosome releases its contents to the injured tissue, healing the tissue
Stem Cell derived exosomes have been shown to be efficacious in a number of studies related to repair of peripheral nerve damage, traumatic brain injury, accelerated wound healing and bone fusion, tissue repair, anti-inflammatory effects, skin regeneration, cartilage regeneration, treatment for injured ligaments/tendons, osteoarthritis, bone regeneration, and vaginal rejuvenation.
Despite these reported effects of exosomes, there are currently no FDA approved exosome products available in the US.
