« Exosomes: Company Spotlights from “A” to “Z” »

In recent years, exosomes have gained attention as a strategy for accessing the therapeutic effects of cells without the risks and difficulties of administering the cells to patients.

Exosomes are small vesicles ranging from 30-100nm in size that are found in nearly all eukaryotic fluids and facilitate a range of important cellular functions. They transfer DNA, RNA, and proteins to other cells, thereby altering the function of the targeted cells.

In recent years, exosomes have gained attention as a strategy for accessing the therapeutic effects of cells without the risks and difficulties of administering the cells to patients.

With at least 22,143 scientific articles published about exosomes and 253 clinical trials underway, these small vesicles have intriguing potential to be used within a range of therapeutic applications.

The term “exosomes” has become an increasingly common Search Term on Google over the past 10 years, [by almost a multiple of ten since 2011] as shown on the graph [available here: https://bioinformant.com/exosomes/].

Despite this flurry of activity, exosomes are coming under increasing scrutiny, with a Public Safety Notification on Exosome Products released December 6, 2019, by the U.S. FDA stating:

“Certain clinics across the country, including some that manufacture or market violative ‘stem cell’ products, are now also offering exosome products to patients. They deceive patients with unsubstantiated claims about the potential for these products to prevent, treat or cure various diseases or conditions… As a general matter, exosomes used to treat diseases and conditions in humans are regulated as drugs and biological products under the Public Health Service Act and the Federal Food Drug and Cosmetic Act and are subject to premarket review and approval requirements.”

Currently, there are no FDA-approved exosome products.
