Abstract
Extracellular vesicles (EVs) are secreted by cells and can be found in biological fluids (e.g., blood, saliva, urine, cerebrospinal fluid, and milk). EV isolation needs to be optimized carefully depending on the type of biofluid and tissue. Human milk (HM) is known to be a rich source of EVs, and they are thought to be partially responsible for the benefits associated with breastfeeding. Here, a workflow for the isolation and lipidomic analysis of HM-EVs is described. The procedure encompasses initial steps such as sample collection and storage, a detailed description for HM-EV isolation by multistage ultracentrifugation, metabolite extraction, and analysis by liquid chromatography coupled to mass spectrometry, as well as data analysis and curation.
