(A) This diagram represents a portion of a relaxed smooth muscle cell, highlighting the arrangement of the actin-containing thin filaments and the myosin-containing thick filaments. This rendering is greatly simplified from the actual arrangement. From the longitudinal orientation, thin filaments arise...
Cardiac muscle cellsare short cylindrical, branching cells about 80 µm in length and 15 µm in diameter with a single, centrally placed nucleus (or occasionally two nuclei). At either end of the nucleus, the cell possesses glycogen deposits andtriglycerides. ...
and is crucial for survival. Smooth muscles play a significant role in the normalanatomyand physiology of blood vessels. A vascularsmooth muscle(VSM) is a type of smooth muscle found in the walls of blood vessels. Mural cell is a term that refers to the combination of connective...

Several gene and cell-therapy studies have been performed on satellite cells, the primary skeletal muscle stem cells involved in muscle regeneration. However, these have mainly been based on artificial replacement or augmentation of the missing protein. Satellite cells are a particularly appealing ...
(milliseconds) to travel between these two nodes. The relative importance of this pathway has been debated since the impulse would reach the atrioventricular node simply following the cell-by-cell pathway through the contractile cells of the myocardium in the atria. In addition, there is a ...

Cell populations C1-C3; C5 used in this experiment, see Supplementary Table S1. See also Supplementary Fig. S1 and Supplementary Dataset Files 1 and 2. Full size image ...
Cell lineages of the tail muscles of ascidian larvae. Diagram of primary and secondary tail muscle lineage development in two species,Halocynthia roretziandCiona robusta. Bottom row: tailbud stages of the two species showing divergent muscle cell contributions color-coded according to conserved lineages...
The refractile outer portion of the inner member of a rod or cone cell. It is located between the myoid and the outer member of the cell, and contains mitochondria. Themyoidis in contact with theexternal limiting membraneof the retina while the outer member is next to thepigment epithelium...
For over a decade, stem cell–based cardiac repair stands as one of the leading strategies for reversing the effects ofmyocardial injury. After the isolation of the firstembryonic human stem cellin 1998[1], ethical considerations and tumor formation have limited their scientific usage[2]. Much ...
