The Endocardium and Heart Valves

open access: yesCold Spring Harbor Perspectives in Biology, 2020
Endocardial cells are specialized endothelial cells that, during embryogenesis, form a lining on the inside of the developing heart, which is maintained throughout life. Endocardial cells are an essential source for several lineages of the cardiovascular system including coronary endothelium, endocardial cushion mesenchyme, cardiomyocytes, mural cells,

A NEW, OTHER THAN ACOUSTIC, QUANTIFICATION METHOD FOR ENDOCARDIUM DETECTION IN ECHOCARDIOGRAPHIC IMAGES

open access: yesImage Analysis and Stereology, 2011
A new, semiautomatic algorithm for tracing outlines of endocardium of newborns that are detectable in echocardiographic images is presented. The main advantage of the method proposed is its low sensitivity to operator errors. Moreover, in contrast to the

Endocardium in Hypoplastic Left Heart Syndrome: Implications from In Vitro Study

open access: yesJournal of Cardiovascular Development and Disease, 2022
Endocardium lines the inner layer of the heart ventricle and serves as the source of valve endothelial cells and interstitial cells. Previously, endocardium-associated abnormalities in hypoplastic left heart syndrome (HLHS) have been reported, including ...

Assessment of Serum Cytokine Concentrations in Infective Endocarditis Patients [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2020
Introduction: Infective Endocarditis (IE) remains a devastating disease despite advances in diagnosis and treatment. The main stay of diagnosis is blood culture, however many cases are culture negative.

β-Lapachone induces heart morphogenetic and functional defects by promoting the death of erythrocytes and the endocardium in zebrafish embryos

open access: yesJournal of Biomedical Science, 2011
Background β-Lapachone has antitumor and wound healing-promoting activities. To address the potential influences of various chemicals on heart development of zebrafish embryos, we previously treated zebrafish embryos with chemicals from a Sigma LOPAC1280™

Geometry Does Impact on the Plane Strain Directions of the Human Left Ventricle, Irrespective of Disease

open access: yesJournal of Cardiovascular Development and Disease, 2022
The directions of primary strain lines of local deformation in Epicardial and Endocardial layers have been the subject of debate in recent years. Different methods led to different conclusions and a complete assessment of strain direction patterns in ...

Strong as a Hippo’s Heart: Biomechanical Hippo Signaling During Zebrafish Cardiac Development

open access: yesFrontiers in Cell and Developmental Biology, 2021
The heart is comprised of multiple tissues that contribute to its physiological functions. During development, the growth of myocardium and endocardium is coupled and morphogenetic processes within these separate tissue layers are integrated.

Some Structural and Chemical Changes in Endocardial Endothelium of Rats in Emotional and Pain Stress Complicated by Hypercholesterolemia

open access: yesGalician Medical Journal, 2017
The objective of the research was to study the content of some neutral lipids of endocardial endothelium in rats in relation to structural changes occurring in it, in the co-existence of emotional and pain stress, as well as alimentary ...

Antagonistic Activities of Vegfr3/Flt4 and Notch1b Fine-tune Mechanosensitive Signaling during Zebrafish Cardiac Valvulogenesis

open access: yesCell Reports, 2020
Summary: The formation of cardiac valves depends on mechanical forces exerted by blood flow. Endocardial cells lining the interior of the heart are sensitive to these stimuli and respond by rearranging into luminal cells subjected to shear stress and ...

Apelin signaling dependent endocardial protrusions promote cardiac trabeculation in zebrafish

open access: yeseLife, 2022
During cardiac development, endocardial cells (EdCs) produce growth factors to promote myocardial morphogenesis and growth. In particular, EdCs produce neuregulin which is required for ventricular cardiomyocytes (CMs) to seed the multicellular ridges ...
