Fig. 1From: Canine colostrum exosomes: characterization and influence on the canine mesenchymal stem cell secretory profile and fibroblast anti-oxidative capacityCharacterization of CCM exosomes. a Representative TEM images of exosomes isolated from CCM. Exosomes appear with characteristic cup-shaped morphology and as round well-delimited vesicles. Bars, 100 nm. b Western blot analysis showing positive expression of ALIX, Hsp-70 and TSG-101 surface-specific exosomal markers. Exposure time: 40 s. Positive control: protein lysate of human adipose mesenchymal stem cells (hAd-MSC). Cropped image (original blot included in the Additional file 4). c Exosomal size distribution profileBack to article page
