PMID	Title	Abstract
30222750	Clinico-pathological significance of exosome marker CD63 expression on cancer cells and stromal cells in gastric cancer.	CD63-positive exosomes might be associated with the interaction between stromal cells and cancer cells. It has been reported that CD63, an exosome marker, is expressed in solid cancer tissues.
30232365	Sensitive and rapid quantification of exosomes by fusing luciferase to exosome marker proteins.	Here, we present a novel system for quantifying secreted exosomes by introducing ectopic or CRISPR/Cas9-mediated knock-in of luciferase-fusion exosome markers such as CD63.
30234974	Magnetic-Based Microfluidic Device for On-Chip Isolation and Detection of Tumor-Derived Exosomes.	By combining magnetic enrichment based on specific phosphatidylserine-Tim4 protein recognition with a new signal transduction strategy in a chip for the first time, the proposed platform enables highly sensitive detection for CD63 positive exosomes as low as 4.39 × 10
30236130	Torquetenovirus detection in exosomes enriched vesicles circulating in human plasma samples.	Exosomes enriched vesicles (EEVs) were extracted from plasma and characterized by Nanoparticle tracking analysis, by western blot for presence of tetraspanin CD63, CD81 and annexin II protein and, finally, by electron microscopy (EM).
30613011	[Cancer stem-like cell-derived exosomes promotes the proliferation and invasion of human umbilical cord blood-derived mesenchymal stem cells].	Piwil2-iCSC-derived exosomes were isolated by ultracentrifugation and identified using transmission electron microscopy,nanoparticle tracking analysis and Western blotting.Exosome uptake assay was used to identify the pathway that Piwil2-iCSCderived exosomes utilized.HucMSCs were divided into control group,PBS intervention group and exosome intervention group,and CCK-8 assay,wound healing assay,Transwell assay,Western blotting and cell karyotype analysis were used to observe the proliferation,migration,invasion,expression levels of MMP2 and MMP9 proteins,and chromosome structure of hucMSCs. The diameter of Piwil2-iCSC-derived exosomes ranged from 50 nm to 100 nm,and most of them were oval or spherical capsules rich in CD9,CD63 and Piwil2 proteins.Exosomal uptake assay showed that the exosomes executed theirs functions after entering the cells.Compared with the control cells and PBS-treated cells,hucMSCs treated with the exosomes showed significantly increased number of proliferating cells ( Piwil2-iCSC-derived exosomes can promote the proliferation,migration and invasion but does not cause cancer-like heterogeneity changes in hucMSCs. To investigate the effect of Piwil2-induced cancer stem-like cell (Piwil2-iCSC)-derived exosomes on the proliferation,migration and invasion of human umbilical cord blood-derived mesenchymal stem cells (hucMSCs).
30622695	Exosomes from hyperglycemia-stimulated vascular endothelial cells contain versican that regulate calcification/senescence in vascular smooth muscle cells.	No abstract available
30626897	Adiponectin promotes muscle regeneration through binding to T-cadherin.	Purified high-molecular multimeric adiponectin similarly accumulated intracellularly and colocalized with CD63-positive endosomes and enhanced exosome secretion in differentiating C2C12 myotubes but not in undifferentiated myoblasts.
30639393	Exosomes populate the cerebrospinal fluid of preterm infants with post-haemorrhagic hydrocephalus.	Exosomal-sized EVs were isolated by differential ultracentrifugation and TEM confirmed the presence of CD63 This is the first reported characterisation of exosomes from the CSF of preterm infants with post-haemorrhagic hydrocephalus.
30642589	In vivo dynamic distribution of multivesicular bodies and exosomes in spleen of DTMUV infected duck.	CD63, the marker of MVBs and exosomes, was distributed in the sheathed capillaries and the periellipsoidal lymphatic sheaths (PELS) of the white pulp.
30668697	Quantitative Proteomics by SWATH-MS of Maternal Plasma Exosomes Determine Pathways Associated With Term and Preterm Birth.	MP exosomes were spherical, had a mean diameter of 120 nm, and were positive for exosomal proteins CD63 and TSG101 irrespective of pregnancy status.
