The sphingosine 1-phosphate receptor-1 (S1PR1) signals in heterogenous populations of mouse adventitial lymphatic (LEC) and arterial endothelial cells (aEC1, aEC2) to regulate chromatin and the transcriptome, thus affecting their phenotypes.
Notch ligands Jag1 and Dll4 and their effector Ephb2 are required in sinus venosus endocardium for primitive coronary vasculature formation and later for arterial differentiation and maturation of coronary endothelium.
Transcriptome analysis reveals an alternative splicing program induced in the arterial endothelium under low-flow inflammatory conditions by platelet and macrophage recruitment and dependent upon the RNA-binding splice factor Rbfox2.
Arterial myocyte PKD2 channels are activated by vasoconstrictor stimuli, which increases blood pressure, are upregulated during hypertension and cell-specific knockout in vivo reduces both physiological blood pressure and hypertension.
Single-cell RNA analysis of brain endothelium identifies the angiogenic venous capillary subset and respective resident endothelial progenitors at the origin of CCM lesions, while arterial endothelial cells are unaffected.
