PMID	Title	Abstract
35639245	Label-Free Analysis of Exosomes with Hairpin Structure-Mediated Multiple Signal Amplification Strategy.	In this method, a designed SMB (Streptavidin magnetic bead)-capture probe is utilized to specially recognize CD63 protein on the surface of exosome.
35655952	Single Extracellular Vesicle Analysis Using Flow Cytometry for Neurological Disorder Biomarkers.	In this study, using flow cytometry to analyze individual neuronal EVs, we show that our plasma EVs isolated by size exclusion chromatography are mainly CD63-positive exosomes of endosomal origin.
35657460	Exosomes Secreted from circZFHX3-modified Mesenchymal Stem Cells Repaired Spinal Cord Injury Through mir-16-5p/IGF-1 in Mice.	No abstract available
35689956	Downregulated miR-129-5p expression inhibits rat pulmonary fibrosis by upregulating STAT1 gene expression in macrophages.	Compared with the mimic NC-exo group, the miR-129-5p-exo group had significantly increased proliferation of fibroblasts, decreased expression of STAT1, and significantly increased expression of COL1A2, COL3A1, fibronectin and α-SMA, and M2 macrophage-secreted exosomes could carry miR-129-5p to fibroblasts.
35695270	Neuroendocrine, inflammatory, and extracellular vesicle responses during the Navy Special Warfare Screener Selection Course.	EVs stained with markers associated with exosomes (CD63), microvesicles (VAMP3), and apoptotic bodies (THSD1) were characterized using imaging flow cytometry and vesicle flow cytometry.
35698293	Mast cell-derived exosomal miR-181a-5p modulated trophoblast cell viability, migration, and invasion via YY1/MMP-9 axis.	Mast cell exosomes were successfully isolated, containing high expressions of CD63 and HSP70 and low expression of Calnexin and could be transported to the cytoplasm of trophoblast cells.
35700522	Isolation of circulating exosomes and identification of exosomal PD-L1 for predicting immunotherapy response.	Herein, we used iodixanol density gradient centrifugation for the isolation and purification of exosomes and label-free detection of exosomal PD-L1 using a biochip based on surface plasmon resonance (SPR-Exo
35708514	Biological characteristics of adipose-derived stem cells from patients with progressive hemifacial atrophy: An in vivo study.	NTA particle size, electron microscopy (TEM), and WB for CD63 and TSG10 were used to detect the exosomes.
35716063	Ascorbate peroxidase-mediated in situ labelling of proteins in secreted exosomes.	In this methodology, a variant of the engineered ascorbate peroxidase APEX, fused to an exosome cargo protein such as CD63, is expressed specifically in exosome-generating vesicles in live cells or in secreted exosomes in the conditioned medium, to induce biotinylation of the proteins in the vicinity of the APEX variant for a short period of time. Mass spectrometry analysis of the proteins biotinylated by this approach in exosomes secreted by kidney proximal tubule-derived cells reveals that oxidative stress can cause ribosomal proteins to accumulate in an exosome subpopulation that contains the CD63-fused APEX variant.
35728610	Analysis of Thrombin-Activated Platelet-Derived Exosome (T-aPDE) Potential for Dental Pulp Regeneration: In-Vitro Study.	This study analyzed the potential of various concentrations of the thrombin-activated platelet-derived exosome (T-aPDE) to regenerate the dental pulp by performing an The hDPSCs were collected from nine third molar teeth of nine healthy donors and were isolated and cultured using the explant method.
