PMID	Title	Abstract
31220525	Exosomal Notch3 from high glucose-stimulated endothelial cells regulates vascular smooth muscle cells calcification/aging.	The presence of exosome markers including CD9, CD63 and TSG101 were also detected in HG-HUVEC-Exo.
31242249	Oral extracellular vesicles in early pregnancy can identify patients at risk of developing gestational diabetes mellitus.	The exosome transmembrane protein CD63 was also detected in the extracellular vesicles of gingival crevicular fluid.
31258635	Scutellarin-treated exosomes increase claudin 5, occludin and ZO1 expression in rat brain microvascular endothelial cells.	The results revealed that treatment with Scu and Scu-treated exosomes enhanced cell viability, reduced cell injury, increased NO levels, upregulated CD63, claudin 5, occludin and ZO1, and decreased LDH and ROS levels.
31268344	Label-Free Exosome Detection Based on a Low-Cost Plasmonic Biosensor Array Integrated with Microfluidics.	The anti-CD63 antibody that is specific to the exosome transmembrane protein CD63 is modified on the surface of the nano-ellipsoids.
31275379	Frizzled-10 Extracellular Vesicles Plasma Concentration Is Associated with Tumoral Progression in Patients with Colorectal and Gastric Cancer.	No abstract available
31298362	Development of a rinsing separation method for exosome isolation and comparison to conventional methods.	Moreover, the exosome markers CD63 and TSG101 were observed in the lysate of all exosome samples that were isolated using each method.
31331170	Electrical and Label-Free Quantification of Exosomes with a Reduced Graphene Oxide Field Effect Transistor Biosensor.	An RGO FET biosensor modified with specific antibody CD63 in the sensing area was fabricated and was used for electrical and label-free quantification of exosomes.
31339911	A cell-based assay for CD63-containing extracellular vesicles.	No abstract available
31349735	Ionizing Radiation Increases the Activity of Exosomal Secretory Pathway in MCF-7 Human Breast Cancer Cells: A Possible Way to Communicate Resistance against Radiotherapy.	The mRNA levels of vital genes involved in exosome biogenesis and secretion including Alix, Rab11, Rab27a, Rab27b, TSPA8, and CD63 were measured by real-time PCR.
31366487	Color-coded Imaging of the Fate of Cancer-cell-derived Exosomes During Pancreatic Cancer Metastases in a Nude-mouse Model.	Mia-PaCa-2 human pancreatic cancer cells expressing red fluorescent protein (RFP) were transduced by exosome-specific pCT-CD63-green fluorescent protein (GFP) and injected in the spleen of nude mice.
