Browsing: Exosome

Exosomes are small, membrane-bound vesicles secreted by cells into the extracellular environment, playing a crucial role in cell-to-cell communication. Typically ranging in size from 30 to 150 nanometers, these vesicles contain various biomolecules, such as proteins, lipids, RNA, and DNA, reflecting the state of their cell of origin. Exosomes are involved in numerous biological processes, including immune responses, tissue repair, and the regulation of cellular activities. In recent years, they have gained significant attention in medical research for their potential as biomarkers for diseases like cancer, and as vehicles for drug delivery in therapeutic applications. Their role in disease progression and their diagnostic potential make them a key focus in biomedical studies.
