The heart consists of a range of tissues. The most important one is cardiac muscle. The cells have the ability to contract and relax through the complete life of the person, without ever becoming fatigued. Each cardiac muscle cell is myogenic. This means it has its own inherent rhythm. Belo...
The heterogeneity of functional cardiomyocytes arises during heart development, which is essential to the complex and highly coordinated cardiac physiological function. Yet the biological and physiological identities and the origin of the specialized cardiomyocyte populations have not been fully comprehended. ...
To elucidate mechanisms how RDN affects failing heart, we studied load-independent indexes of ventricular function, gene markers of myocardial remodeling, and cardiac sympathetic signaling in HF, induced by chronic volume overload (aorto-caval fistula, ACF) of Ren2 transgenic rats. Volume overload ...
Cell transplantation to prevent congestive heart failure in patients with inherited dilated cardiomyopathy might require the use of noncardiac donor cells unaffected by the genetic defect and cryopreservation to permit cell storage until the time of transplantation. However, the effects of cryopreservation ...
Describe how the structure of epithelial tissue relates to its function. Describe some of the structures of a muscle cell. List and discuss muscle tissue properties. Explain how cardiac muscle cells are able to function as a syncytium despite being composed of single-cell, mononucleated muscle ...
Skeletal muscle contains a designated population of adult stem cells, called satellite cells, which are generally quiescent. In homeostasis, satellite cells proliferate only sporadically and usually by asymmetric cell division to replace myofibres damaged by daily activity and maintain the stem cell pool...
of Kdr-overexpressed hearts (Fig.1landSupplementary information, Figs.S7andS8). We also assessed cardiac function using echocardiography (Supplementary information, Fig.S9a). One day before the surgery, there was no significant difference in heart function between the Kdr-overexpressed and the control...
For example, gap junctions in cardiac muscle tissue allow for coordinated contraction of the heart. Summary of epithelial tissue surfaces and characteristicsTable quiz Characteristics Highly cellular, function as receptors, form a barrier, minimal extracellular matrix, avascular, innervated, Basal ...
At the organism level, cardiovascular function may be defined as the adequate delivery of blood and oxygen to the tissues to meet their metabolic needs. Note that this definition, while appropriate to heart failure, disregards the performance of the cardiac chambers themselves. At the organ level...
