| 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. [Journal of Clinical Investigation] |

|
| 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.

|
|
| 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. [Nature Communications] |
|
|
|
| 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.

|
|
| Scientists introduce a novel strategy for the generation of prevascularized islet organoids by the fusion of pancreatic islet cells with functional native microvessels. [EMBO Molecular Medicine] |

|
|
| 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. [Proceedings of the National Academy of Sciences of the United States of America] |
|
|
|
| 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. [Proceedings of the National Academy of Sciences of the United States of America] |
|
|
|
| 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. [Acta Biomaterialia] |
|
|
|
| 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.

|
|
| 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.

|
|
| Researchers summarize recent progress in the understanding of regulated fatty acid, glucose, and insulin transport across the endothelium and discusses its pathophysiological implications. [Trends in Cell Biology] |
|
|
|
| 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. [Cell Death & Disease] |

|
| Roche announced that the European Commission has approved Tecentriq® in combination with Avastin® for the treatment of adult patients with advanced or unresectable hepatocellular carcinoma who have not received prior systemic therapy. [Roche] |
