Extracellular vesicles (EVs), through their complex cargo, can reflect the state of cell origin and change functions phenotypes other cells. These features indicate strong biomarker therapeutic potential have generated broad interest, as evidenced by steady year-on-year increase in numbers scientific publications about EVs. Important advances been made EV metrology understanding applying biology. However, hurdles remain to realising EVs domains ranging from basic biology clinical applications due challenges nomenclature, separation non-vesicular extracellular particles, characterisation functional studies. To address opportunities this rapidly evolving field, International Society for Vesicles (ISEV) updates its 'Minimal Information Studies Vesicles', which was first published 2014 then 2018 MISEV2014 MISEV2018, respectively. The goal current document, MISEV2023, is provide researchers with an updated snapshot available approaches advantages limitations production, multiple sources, including culture, body fluids solid tissues.

Abstract In this study we tested whether a protein corona is formed around extracellular vesicles (EVs) in blood plasma. We isolated medium‐sized nascent EVs of THP1 cells as well Optiprep‐purified platelets, and incubated them EV‐depleted plasma from healthy subjects patients with rheumatoid arthritis. were subjected to differential centrifugation, size exclusion chromatography, or density gradient ultracentrifugation followed by mass spectrometry. Plasma protein‐coated had higher compared the ones carried numerous newly associated proteins. Interactions between proteins confirmed confocal microscopy, capillary Western immunoassay, immune electron microscopy flow cytometry. identified nine shared EV (ApoA1, ApoB, ApoC3, ApoE, complement factors 3 4B, fibrinogen α‐chain, immunoglobulin heavy constant γ2 γ4 chains), which appear be common among EVs, viruses artificial nanoparticles An unexpected finding was high overlap composition aggregates. This explained our that besides diffuse, patchy corona, large aggregates also associate surface EVs.

Abstract Extracellular vesicles (EVs) play a key role in many physiological and pathophysiological processes hold great potential for therapeutic diagnostic use. Despite significant advances within the last decade, issue of EV storage stability remains unresolved under investigated. Here, we aimed to identify conditions stabilizing EVs comprehensively compared impact various buffer formulations at different temperatures on derived from cellular sources up 2 years. features including concentration, diameter, surface protein profile nucleic acid contents were assessed by complementary methods, engineered containing fluorophores or functionalized proteins utilized compare uptake ligand binding. We show that storing PBS over time leads drastically reduced recovery particularly pure samples all tested, starting already days. further report using as diluent was found result severely rates minutes. Several tested new largely prevented observed effects, lead candidate being supplemented with human albumin trehalose (PBS‐HAT). PBS‐HAT facilitates clearly improved short‐term long‐term preservation stored ‐80°C, throughout several freeze‐thaw cycles, when downstream applications.

A functional corona around extracellular vesicles enhances angiogenesis, skin regeneration and immunomodulation

Опубликована: Апрель 1, 2022

Abstract Nanoparticles can acquire a plasma protein corona defining their biological identity. Corona functions were previously considered for cell‐derived extracellular vesicles (EVs). Here we demonstrate that nano‐sized EVs from therapy‐grade human placental‐expanded (PLX) stromal cells are surrounded by an imageable and functional when enriched with permissive technology. Scalable EV separation cell‐secreted soluble factors via tangential flow‐filtration (TFF) subtractive tandem mass‐tag (TMT) proteomics revealed significant enrichment of predominantly immunomodulatory proangiogenic proteins. Western blot, calcein‐based flow cytometry, super‐resolution electron microscopy verified PLX‐EVs partly protected proteins protease digestion. significantly ameliorated skin regeneration angiogenesis in vivo, induced differential signalling immune cells, dose‐dependently inhibited T cell proliferation vitro. removal size‐exclusion or ultracentrifugation abrogated angiogenesis. Re‐establishing artificial cloaking fluorescent albumin as model defined was depicted microscopy, zeta‐potential shift, served proof‐of‐concept. Understanding formation will improve rational EV‐inspired nano‐therapy design.

Extracellular vesicles (EVs) are lipid-membrane enclosed nanoparticles that play significant roles in health and disease. EVs abundant body fluids carry an array of molecules (proteins, lipids, nucleic acids glycans) reflect the identity activity their cell-of-origin. While advent high throughput omics technologies has allowed in-depth characterisation EV compositions, how these molecular species spatially distributed within structures is not well appreciated. This particularly true surface where a plethora reported to be both integral peripherally associated membrane. coronal layer or 'atmosphere' surrounds membrane contributes large, highly interactive dynamic area responsible for facilitating interactions with extracellular environment. The harbours parent cells, which likely valuable property context diagnostic liquid biopsies. In this review, we describe current understanding mechanical, electrostatic properties offer biomarker potential contribute interactome.

Abstract Skin wounds are characterized by injury to the skin due trauma, tearing, cuts, or contusions. As such injuries common all human groups, they may at times represent a serious socioeconomic burden. Currently, increasing numbers of studies have focused on role mesenchymal stem cell (MSC)-derived extracellular vesicles (EVs) in wound repair. cell-free therapy, MSC-derived EVs shown significant application potential field repair as more stable and safer option than conventional therapy. Treatment based can significantly promote damaged substructures, including regeneration vessels, nerves, hair follicles. In addition, inhibit scar formation affecting angiogenesis-related antifibrotic pathways promoting macrophage polarization, angiogenesis, proliferation, migration, inhibiting excessive matrix production. Additionally, these structures serve scaffold for components used repair, be developed into bioengineered support trauma Through formulation standardized culture, isolation, purification, drug delivery strategies, exploration detailed mechanism will allow them clinical treatments conclusion, EVs-based therapies important prospects Here we provide comprehensive overview their current status, potential, associated drawbacks.
