    Non-Productive Angiogenesis Disassembles Aß Plaque-Associated Blood Vessels

    Researchers showed that Aß plaque-associated NPA locally disassembles blood vessels, leaving behind vascular scars, and that microglial phagocytosis contributes to the local loss of endothelial cells.

    Abstract

    Neuregulin-1 Compensates for Endothelial Nitric Oxide Synthase Deficiency

    Scientists hypothesized that NRG1 could compensate for endothelial nitric oxide (NO) synthase (eNOS) deficiency. They characterized eNOS null and wild type mice by cardiac ultrasound and histology and determined circulating NRG1 levels.

    Abstract

    Vascular Deficiencies in Renal Organoids and Ex Vivo Kidney Organogenesis

    The authors comprehensively assessed the vasculature in two distinct kidney organoid models as well as in explanted embryonic kidneys.
