Book excerpt: This detailed book provides an exhaustive picture of current methods to detect, isolate, and analyze extracellular vesicles (EVs) from diverse sources, now seen as potential disease biomarkers as well as tools for the development of new therapies. Beginning with a section on detection and isolation of EVs, the volume continues with chapters covering different methods to isolate and quantify EVs from specialized tissues/organs and body fluids, methods devoted to analyzing EV components, as well as cutting-edge methods to engineer EVs. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Extracellular Vesicles in Diagnosis and Therapy serves as an ideal guide for researchers seeking to learn more about the complexities of cell-to-cell communication.
