Inhibition and Rescue of Hyperglycemia‐Induced Cellular Senescence by Mitochondrial Transfer from Enucleated Mesenchymal Stem Cell‐Derived Microvesicles for Chronic Wound Healing

Advanced Science, EarlyView.
This study develops enucleated MSC‐derived microvesicles (Mito@euMVs) to deliver functional mitochondria for optimizing wound repair. By efficiently encapsulating mitochondria, Mito@euMVs rejuvenate hyperglycemia‐induced senescent fibroblasts and HUVECs. Using PVA microneedle patches, the therapeutic efficacy of Mito@euMVs is validated in diabetic rats

Platelet Microvesicles (Microparticles) in Cardiac Surgery [PDF]

Journal of Cardiothoracic and Vascular Anesthesia, 2016
SIGNIFICANT POSTOPERATIVE BLEEDING is a common risk of cardiac surgery, with approximately 3.5% of patients requiring surgical re-exploration.1 Re-exploration is associated with adverse outcomes, including infections, ischemia, and increased 30-day mortality.2 Similar adverse outcomes are related to erythrocyte transfusions associated with cardiac ...

Impact of Chemotherapy on Extracellular Vesicles: Understanding the Chemo-EVs

Frontiers in Oncology, 2019
Chemotherapy is the standard go-to treatment for cancer besides surgery and radiation. It has recently come to light that the interaction between chemotherapy and the immune system is important in maintaining tumor immunity as well as influencing the ...

Endothelial cells regulate astrocyte to neural progenitor cell trans-differentiation in a mouse model of stroke

Nature Communications, 2022
Damaged brains try to repair themselves by producing neurons in areas where neurogenesis does not normally occur. Here, the authors show that brain endothelial cells provide microvesicle-encased signals that convert parenchymal astrocytes into neural ...

Shear-induced integrin signaling in platelet phosphatidylserine exposure, microvesicle release, and coagulation.

Blood, 2018
It is currently unclear why agonist-stimulated platelets require shear force to efficiently externalize the procoagulant phospholipid phosphatidylserine (PS) and release PS-exposed microvesicles (MVs).

Bionic Nanostructures Create Mechanical Signals to Mediate the Composite Structural Bone Regeneration Through Multi‐System Regulation

Advanced Science, EarlyView.
Inspired by the structural and functional characteristics of bone, bionic nanomaterials combined with nanotechnology can more accurately replicate stem cell niches, enabling the design of bone tissue engineering scaffolds with diverse nanoscale properties to promote stem cell migration, proliferation, and differentiation. This precise control over stem

In Situ Programming of the Tumor Microenvironment to Alleviate Immunosuppression for Pancreatic Cancer Immunotherapy

Advanced Science, EarlyView.
cmExoaCD11b induced the repolarization of immunosuppressive M2 macrophages into pro‐inflammatory M1 phenotype, thereby promoting the proliferation and activation of CD8+ T cells and reversing the immunosuppressive state of the tumor microenvironment.

Sorting Mechanisms for MicroRNAs into Extracellular Vesicles and Their Associated Diseases

Cells, 2020
Extracellular vesicles (EV) are secretory membranous elements used by cells to transport proteins, lipids, mRNAs, and microRNAs (miRNAs). While their existence has been known for many years, only recently has research begun to identify their function in ...

Circulating Tumor Cells Shed Shearosome Extracellular Vesicles in Capillary Bifurcations That Activate Endothelial and Immune Cells

Advanced Science, EarlyView.
Using microfluidic models of capillary networks, this study discovered that fluid shear stresses on circulating tumor cells transiting through capillary‐sized bifurcations shed a novel class of shear‐dependent large extracellular vesicle, “shearosomes”, whose proteome comprises of over 3000 distinct proteins.
