The myocardium is highly organized tissue, composed of several cell types that include smooth muscle cells, fibroblasts, and cardiac myocytes. 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. Electron microscopes can be used to visualize objects that are too small to see when using a light microscope—for example, the microvilli, mitochondria and the junctions between cells. In the Microscopy lab, you will examine a chicken intestine slide that is specially prepared for a transmission electron microscope.

Cardiac cell therapy with adult stem cells. Cardiac cell transplantation was first described in the mid-1990s by several groups using various cell types ( 70, 115 ). Transplanting cells directly into and around the injured myocardium reduced scar formation and improved LV function postmyocardial infarction ( 70, 114 ).What the Cardiac Myocyte Does. The pumping of the heart is made possible by interactions between contractile proteins that transform the chemical energy derived from adenosine triphosphate (ATP) into mechanical work. These interactions are activated by a process called excitation–contraction coupling, in which plasma membrane depolarization ...A myocyte (also known as a muscle cell) is the type of cell found in some types of muscle tissue.
