Fig. 2From: Congenital microtia patients: the genetically engineered exosomes released from porous gelatin methacryloyl hydrogel for downstream small RNA profiling, functional modulation of microtia chondrocytes and tissue-engineered ear cartilage regenerationIdentification of 3D-Exo released from disparate number of ADSCs (Exo 2, Exo 4 and Exo 6). AÂ Particle size distribution measured using nanoparticle tracking analysis. BÂ Morphological characterization via transmission electron microscopy. Scale bar: 100Â nm. CÂ Protein markers of 3D-Exo and their corresponding parental ADSCs extract quantified by western blottingBack to article page
