We at BioSima believe that exosome-mediated therapies may represent a very promising and innovative therapeutic alternative, being cell-free, non-invasive, less immunogenic and non-toxic for diagnosis and treatment of several diseases. Furthermore, exosomes may play an important informative role on the individual’s health, providing crucial information about the type of molecules secreted by different cells, which can be very effective not only in the therapeutic but also in the diagnostic context.
