The heart features four types of valves which regulate the flow of blood through the heart. These valves have been clearly shown in the labeled diagram of the heart. They permit blood flow in one direction only, and prevent backflow of blood. The four types of valves are: Tricuspid Valve T...
The human heart is part of the cardiovascular system. The main function of the heart is to supply oxygenated blood to the rest of the body for survival and to thrive. A human heart diagram is shown below, which shows how the heart accomplishes this function. The human heart labeledWhat...
ESERCA was labeled with a monospecific antibody detecting the endogenous protein (SERCA). Optical slices of adult heart muscle fibers (A–C) or ventral longitudinal muscle fibers (D–F) are shown. Scale bars: 50 µm; ventral
Analyses of ashed muscle tissue show that the uptake of Ca(45) by isolated frog heart ventricles from normal Ringer's solution containing 1 mM Ca reaches a maximum value in about 30 minutes of perfusion which is not exceeded after 3 hours of perfusion. The average amount of this labeled Ca...
We also demonstrated that in the mice with TAC, hypertrophy of the cardiomyocytes was most pronounced in the inner muscle layer of the left ventricle compared to the outer muscle layer of the left ventricle, making it the most suitable for analysis of the model. In contrast, no hypertrophy ...
aDiagram of the RA+ organoid and monolayer cell differentiation workflow. RA was added to induce the atrial cell lineages.bRepresentative image of the cells at different differentiation stages. The green signal represents CMs labeled by Actn2-eGFP.cThe diameter of RA+ organoids from day 0 to ...
For the purpose of human heart tissue engineering or repairing ventricular muscle damage, using a homogeneous population of ventricular-specific myocytes would be more attractive. Since currently there are no specific surface markers for ventricular cardiomyocytes, selection of ventricular myocytes usually ...
or when it is transplanted from a donor to a recipient. The normal pacemaker activity is located in a specialized group of cells that comprise thesinoatrial nodeorSA node. The SA node consists of a small strip of modified muscle tissue, about 20mm×4mm, on the posterior wall of theatriumne...
After microinjection, suture the muscle layer covering the fourth ventricle. Maintain the body temperature of the mouse at 37 °C with a heating pad until the animal recovers from surgery. Mice were sacrificed, and the co-localization AAV9-TIE-shRNA (cGAS) (containing ZsGreen fluorescent ...
labeled f1indicates the heart activity of one twin, while the waveform labeled f2indicates the heart activity of the second twin. The maternal heart complex, labeled M, is also clearly evident. It will be noted that the fetal complex of each twin is of opposite polarity to the other, ...
