Fig. 1From: The molecular mechanism of human stem cell-derived extracellular vesicles in retinal repair and regenerationThe signalling delivery methods of extracellular vesicles. (I) EVs carry specific signalling molecules on the surface of their lipid membranes and bind to receptors on the surface of target cells; (II) EVs transport receptors via membrane fusion with recipient cells; (III) EVs release the cargo packed inside the vesicle directly into the recipient cytoplasm.
