Exosomes are microscopic vesicles that our cells naturally secrete, functioning as "messengers" that carry important information between cells. They're only 30-200 nanometers in diameter and contain proteins, lipids, and genetic material that regulates the function of target cells.
When we talk about autologous exosomes, we mean those that come from the patient themselves. This means they're isolated from your own blood or tissue and then used for your treatment, which ensures absolute compatibility and virtually zero risk of allergic reactions.
The difference from
allogeneic exosomes (which come from other organisms) is that autologous ones are recognized by your immune system as "its own," which increases both the effectiveness and safety of the treatment.
