Extracellular Vesicles in Brain Cancer Blood Testing

Can a new screening for tiny cell particles help monitor the progress of brain cancers?

Extracellular vesicles (EVs) are a diverse group membranous structures that are shed from all cells of the body. They include exosomes, oncosomes, migrasomes and microvesicles, which play a role in cell-to-cell communication. Because cancer cells also shed these structures (Figure 1), and because they can be found in blood and other biological fluids, researchers are investigating whether they can capture cancer-related EVs as a noninvasive test for brain cancers at the time of diagnosis, through treatment and post-therapy. Read more about this new study from Shannon Stott, PhD and Brian Nahed, MD, MSc.
