Exosomes

Exosomes are small membrane vesicles of endocytic origin secreted by most cell types in vitro. Cells continuously secrete a large number of microvesicles, exosomes and small molecules into the extracellular space. Exosomes have been shown to contain mRNA and miRNA and they are able to mediate communication between cells, by transport of RNA and proteins which can be functionalized in the recipient cell. The ability to transport bioactive cargoes, gives exosomes innate therapeutic potential as a natural drug carrier. Efficient techniques for loading drugs into exosomes to utilize the natural carrier capabilities of these vesicles remains to be elucidated.

Applications of Exosomes

The presence exosomes in blood, saliva, and urine paves the way for the possible application of exosomes as a diagnostic marker for diseases. Many diseases are difficult to detect by the methods and equipment available today and there is a growing demand for development of new non‐invasive methods to detect diseases in early stages. The use of exosomes as markers of disease is being investigated to cement their potential as a non-invasive diagnostic tool for early detection of many diseases, in particular cancers. This, however, relies on thorough characterisation of exosomes in both healthy and diseased states

An important factor to understanding the roles of exosomes is knowledge of their biodistribution. Currently, the number of publications describing the biodistribution of exosomes is limited. The main reason being the lack of a robust fluorescent label that can be visualised in vivo. Mapping the specific cell type derived exosomes can increase our knowledge on the roles of exosomes in the organism, as well as help to identify natural targeting systems.

Isolation, Characterisation and Fluorescent Labelling

The most common isolation protocol uses a differential centrifugation to fractionate cells, microvesicles, and exosomes, which are pelleted by ultracentrifugation. After vesicles are secreted from cells into the extracellular environment, it difficult to separate the different subpopulations of vesicles to obtain a pure sample. We have developed methods to optimise isolation and thorough characterisation procedures to obtain pure and well-characterised exosomes. Furthermore, we have developed a simple method for labelling of exosomes with a robust fluorescent label that can be visualised in vivo, allowing investigation of the biodistribution of different cell derived exosomes.
