The meaning of CARDIAC MUSCLE is the principal involuntary-muscle tissue of the vertebrate heart made up of striated fibers joined at usually branched ends and functioning in synchronized rhythmic contraction.
Cardiac muscle cells form a highly branched cellular network in the heart. They are connected end to end byintercalated disksand are organized into layers of myocardialtissuethat are wrapped around the chambers of the heart. Thecontractionof individual cardiac muscle cells produces force and shortening...
Skeletal muscleLong syncytial, multinucleated cells; orderly arrangement of myosin and actin filaments gives striated appearance; each fiber is directly innervated by a motor neuronRapid, powerful contractions; can shorten to 60%–80% of resting length; contraction is initiated by the central nervous ...
In many ways, cardiac muscle is something of a hybrid between skeletal and visceral "smooth" muscle. In its unceasing electrical and mechanical rhythmicity, it is reminiscent of many single-unit visceral muscles, but in its banded appearance, it resembles more the nature of skeletal muscle than ...
Senescence in vascular smooth muscle cells VSMCs function cooperatively with ECs to regulate blood pressure, vascular tone, and blood flow. Vascular and interstitial cardiac cells exhibit cell cycle arrest, inflammation activation, p16INK4A expression, telomere shortening, and acquisition of SASP during...
Cellular growth of cardiac muscle after birth. 来自 NCBI 喜欢 0 阅读量: 23 作者:L Bugaisky,R Zak 摘要: Present concepts concerning DNA synthesis in the heart have been reviewed, and a speculative theory presented involving control of DNA synthesis in the developing heart. Research describing ...
The endocardium is activated immediately after injury and promotes cardiac muscle regeneration by producing growth factors. Research now shows that innate immune signaling is crucial for the regenerative function of the endocardium. Kazu Kikuchi

The HL-1 cell line, a mouse cardiac muscle cell line, is derived from the AT1 mouse atrial cardiomyocyte tumor lineage24. HL-1 cells were used for ChIP assays and cellular functional assays. Before induction of hypoxia in cells, the medium was replaced with a sugar-free and serum-free ...
ERRs, including ERRα, ERRβ, and ERRγ, are orphan nuclear hormone receptors contributing to physiological signaling pathways in the heart, pancreatic β-cells, liver, and skeletal muscle. Especially in the heart, several studies have revealed that ERRs regulate genes encoding FAO and oxidative ph...
