Fig. 1From: Milk-derived small extracellular vesicles: nanomaterials to promote bone formationIsolation and identification of Milk-sEVs. A Schematic showing the extraction of Milk-sEVs by differential centrifugation; B observation of the structure of Milk-sEVs under TEM (× 100,000); C NTA detection of the median particle size of Milk-sEVs; D western blotting was used to analyze protein expression of the sEVs markers CD63, CD81, and ALIX and the microcapsule surface marker CD40 in different batches of Milk-sEVsBack to article page
