Stabilized Extracellular Vesicle Formulations for Inhalable Dry Powder Development

open access: yesSmall, EarlyView.
Extracellular vesicles (EVs) hold promise for chronic obstructive pulmonary disease (COPD) treatment but face challenges with storage and delivery. This study demonstrates the stabilization of lung fibroblast‐derived EVs using inulin, enabling freeze‐drying and spray‐drying.
