Natural killer cell-derived extracellular vesicles (NK-EVs) hold promising potential as cancer biotherapeutics. This methodology-based study presents a scalable closed-loop biomanufacturing workflow designed to continuously produce and isolate large quantities of high-purity NK-EVs. In-process control testing is performed throughout the biomanufacturing workflow, ensuring the EVs meet quality standards for product release.
