Noun1.cardiac muscle - the muscle tissue of the heartcardiac muscle - the muscle tissue of the heart; adapted to continued rhythmic contraction
muscular tissue, muscle - animal tissue consisting predominantly of contractile cells
ticker, heart, pump - the hollow muscular organ located behind the sternum and between the lungs; its rhythmic contractions move the blood through the body; "he stood still, his heart thumping wildly"
cardiac pacemaker, SA node, sinoatrial node, pacemaker - a specialized bit of heart tissue that controls the heartbeat
papillary muscle - any of several muscles associated with the atrioventricular valves; "the papillary muscles contract during systole to prevent regurgitation of blood into the atria"
atrioventricular bundle, atrioventricular trunk, bundle of His, truncus atrioventricularis - a bundle of modified heart muscle that transmits the cardiac impulse from the atrioventricular node to the ventricles causing them to contract
atrioventricular node - a node of specialized heart muscle located in the septal wall of the right atrium; receives impulses from the sinoatrial node and transmits them to atrioventricular bundle
myocardium - the middle muscular layer of the heart wall
Purkinje fiber - a specialized cardiac muscle fiber that is part of the Purkinje network
Purkinje network, Purkinje's system, Purkinje's tissue - a network of Purkinje fibers that carry the cardiac impulse from the atrioventricular node to the ventricles of the heart and causes them to contract

Developmental expression of myostatin in cardiomyocytes and its effect on foetal and neonatal rat cardiomyocyte proliferation.
Within a few days after injecting the gel, their heart tissue showed increased biomarkers of cardiomyocyte proliferation.
In addition, the study showed that NaHS pretreatment improved mitochondrial DNA number in neonatal mouse cardiomyocyte.
13 Interestingly, various methods using a transgenic mouse model with beta-galactosidase, 14C labeling of cardiomyocyte nuclei and multi-isotope imaging mass spectrometry showed a renewal rate not more than 1-2% per year.
This is particularly important in modeling of diseases caused by malfunctioning of potassium channels, as different types of potassium channels play a key role in cardiomyocyte repolarization in different species [1].
Moreover, mammalian target of rapamycin (mTOR), which is also essential for cardiomyocyte development, growth, and functions, regulates mitochondrial fatty acid utilization in the heart [8].
Pharmacological inhibition of NOS leads to slowing down or stopping cardiomyocytes differentiation, which suggests that cardiomyocyte-originated NO together with the endothelial NO may also play an important role in cardiomyogenesis at some stage, which probably corresponds to the later stage of the pillowy formation and early myocardial compactness.
The exacerbation of myocardial damage may eventually lead to cardiomyocyte apoptosis and impaired myocardial function.
The expression of cardiomyocyte markers has been observed via the co-culturing of mesenchymal stem cells with cardiomyocytes.
The mechanical integrity of the nanotube scaffold was also stronger, allowing it to withstand repeated cardiomyocyte contractions, whereas the gel lacking nanotubes ruptured quickly.
About the xCELLigence System RTCA Cardio Instrument The latest member of the xCELLigence product family, the RTCA Cardio Instrument is a 96-well cell analyzer for the dynamic monitoring of cardiomyocyte beating and cellular events by impedance readings.
While syndecan-2 expression in cardiac non-myocytes is in apparent contrast to the strict cardiomyocyte expression observed in the current study, a direct comparison of data obtained from an immunohistochemical analysis of early stage chick cardiac tissue (day 3-5) with molecular analysis of later stage rat cardiac mRNA is difficult due to the species difference and the tremendous morphogenetic activity that occurs between early and late stages of embryogenesis.
