Joy Kong, MD explains why exosomes marketed as stem cell treatments are not actually stem cells. Exosomes are tiny particles secreted by stem cells that carry growth factors and reduce inflammation, but isolated exosome products can't adapt to what your body needs the way living cells can.
A lot of people thought the exosomes are actually stem cells somehow. But exosomes are secretion products from stem cells. Stem cells are the mothers of exosomes. They are secreting these exosomes, which are really a lipid bilayer that the cells pinch off to communicate with other cells. So these are little nanoparticles or packages that's full of growth factors. So they are important, and I use that in our clinic all the time, because they're very anti inflammatory, they can produce profound changes, but they are not cells. Because cells have the ability to make exosomes and make it according to your demand, the demand of your tissue and of the situation. They can be very helpful, but they're not as targeted as what the cells can secrete in your body according to your need.
