Cardiomyocytes are the true cardiac muscle cells that build up the muscle walls (called myocardium) of both atria (the chambers in which blood enters the heart) and the ventricles (the chambers where blood is collected and pumped out of the heart). These cells can shorten and lengthen their myofibers to create the pumping force of the heart.

Also known as myocardiocytes, cardiomyocytes are cells that make up the heart muscle/cardiac muscle. As the chief cell type of the heart, cardiac cells are primarily involved in the contractile function of the heart that enables the pumping of blood around the body.

2005年9月1日 · Cardiomyocytes are the cells responsible for generating contractile force in the intact heart. Specialized cardiomyocytes form the cardiac conduction system, responsible for control of rhythmic beating of the heart.

The fundamental contractile cell of the myocardium is the myocyte. The purpose of this review is to examine the structural components of the myocyte and then to place these components into a functional context with respect to the contractile process.

The cardiac myocyte is a specialized striated muscle cell that is approximately 25 μ in diameter and about 100 μ in length. They form a branching network of cells that are connected by intercalated discs. The myocyte is composed of bundles of myofibrils that contain myofilaments.

2021年9月14日 · The fundamental contractile cell of the heart is the cardiomyocyte. Specialized CMs form the cardiac conduction system, a collection of nodes and cells which initiate and co-ordinate the rhythmic beating of the heart. A contractile cardiomyocyte in the adult human heart is cylindrical in shape and about 100 μm long and 10–25 μm in diameter.

Cardiac myocyte model systems have been developed to study this process. Here we focus on cell culture tools, including primary cells, immortalized cell lines, human stem cells, and their morphological and molecular responses to pathological stimuli.

2002年5月31日 · In the present study, we review approaches and studies that have shed some light on cardiomyocyte cell cycle regulation. For reference, an initial description of cardiomyogenic induction and morphogenesis is provided, which is followed by a summary of published cell cycle analyses during these stages of cardiac ontology.

When stressed, cardiomyocytes undergo hypertrophic growth and apoptotic responses in vivo as well as in cell culture models. Such changes predispose to heart failure in the longer term. The heart is the first formed organ in the developing fetus.
