    ANGPTL2-Containing
    Small Extracellular Vesicles from Vascular Endothelial Cells Accelerate Leukemia Progression

    The authors used seven cell-type specific mouse Cre lines to conditionally knockout Vps33b in Cdh5+ or Tie2+ endothelial cells, Lepr+ bone marrow perivascular cells, Osx+ osteo-progenitor cells, Pf4+ megakaryocytes and Tcf21+ spleen stromal cells.

    Genetically Engineered Magnetic Nanocages for Cancer Magneto-Catalytic Theranostics

    Scientists demonstrated that encapsulin-produced magnetic iron oxide nanocomposites had excellent magnetic saturation and remnant magnetization properties, featuring superior magnetic-to-thermal conversion efficiency with an ultrahigh specific absorption rate of 2390 W/g to overcome the critical issues of magnetic hyperthermia therapy.

    Slug
    Regulates the Dll4-Notch-VEGFR2 Axis to Control Endothelial Cell Activation and Angiogenesis

    Both endothelial cell-specific Slug re-expression and reduced Notch signaling, either by γ-secretase inhibition or loss of Dll4, rescued retinal angiogenesis in SlugKO mice.

    Dissecting the Chemoresistance Mechanisms in B Cell Acute Lymphoblastic Leukemia Bone Marrow Niche

    Investigators demonstrated an in vitro organotypic “leukemia-on-a-chip” model to emulate the in vivo B cell acute lymphoblastic leukemia (B-ALL) bone marrow (BN) pathology and comparatively studied the spatial and genetic heterogeneity of the BM niche in regulating B-ALL chemotherapy resistance.

    Improvement
    of Islet Transplantation by the Fusion of Islet Cells with Functional Blood Vessels

    Scientists introduce a novel strategy for the generation of prevascularized islet organoids by the fusion of pancreatic islet cells with functional native microvessels.

    Allosteric Peptide Inhibitor of HIF-1α Regulates Hypoxia-Induced Retinal Neovascularization

    Researchers showed that a peptide fragment of CITED2 was taken up by retinal cells and efficiently regulated pathological angiogenesis in murine models of ischemic retinopathy.

    CRISPR-Cas9 Screen Identifies Mitochondrial Translation as an Essential Process in Latent KSHV Infection of Human Endothelial Cells

    Using a pooled CRISPR-Cas9 lentivirus library, researchers identified host factors that were essential for the survival or proliferation of latently infected endothelial cells in culture, but not their uninfected counterparts.

    Bone
    Marrow Stromal Cells Stimulated by Strontium-Substituted Calcium Silicate Ceramics: Release of Exosomal miR-146a Regulates Osteogenesis and Angiogenesis

    Researchers showed that bone marrow stem cell-derived exosomes after strontium-substituted calcium silicate stimulation could significantly promote in vitro angiogenesis of human umbilical vein endothelial cells, which might be attributed to elevated pro-angiogenic miR-146a cargos and inhibition of Smad4 and NF2 proteins.

    Non-Coding RNA MIAT Regulates Blood Tumor Barrier Permeability by Functioning as a Competing Endogenous RNA

    The authors demonstrated that MIAT, ZAK, and phosphorylated NFκB-p65 were upregulated, while miR-140-3p was downregulated in glioma-exposed endothelial cells of blood-tumor barrier compared with those in endothelial cells co-cultured with astrocytes of blood–brain barrier.

    Kinase M2 Mediates the Glycolysis in the Lymphatic Endothelial Cells and Its Potential Relation to the Progression of Lymphatic Malformations

    The glycolysis index, including glucose uptake, ATP and lactate production stayed at a relatively high level in human dermal lymphatic endothelial cells (HDLECs) compared with HUVECS, while inhibition of PKM2 by shikinon or PKM2 knockdown could significantly suppress glycolysis, migration, tubular formation, and invasion of HDLECs.

    Abstract

    Age-Related Cerebral Small Vessel Disease and Inflammaging

    Investigators discuss recent findings in the pathophysiology of inflammaging and their effects on the development of age-related cerebral small vessel diseases (CSVD). They speculate the inflammaging as a potential target for future therapeutic interventions to delay or prevent the progression of the age-related CSVD.
