It is the presence of cardiomyocytes that results in the early beating of the heart. Cardiomyocytes, or cardiac muscle cells are the main type of heart cells and act as the motor unit to drive heart ...

But in the adult heart, "cardiomyocytes barely divide ... severely impairing heart contraction. To investigate the mechanism through which SRSF3 supports heart contraction, the team compared ...

BACKGROUND: Dilated cardiomyopathy (DCM) is substantially influenced by genetic factors. Sarcomere function is intricately associated with other organelles, particularly the reciprocal regulation ...

Representative compounds were added to cardiomyocytes in a 1:3 dilution series to determine IC50 values. As before, cardiomyocyte contractions were visualized using the EarlyTox Cardiotoxicity dye ...

How the cardiomyocytes that we start developing ... important structures that help to coordinate sarcomere contraction. These too were greatly disrupted in the mutant myocytes.

"The intracellular effects of focused near-infrared femtosecond laser irradiation are shown to cause contraction in cultured neonatal rat cardiomyocytes. By periodic exposure to femtosecond laser ...

Mitochondria are the energy source for heart muscle contractions. TBX20 appeared to help the mitochondria in the induced-cardiomyocytes switch to an adult cardiomyocyte-like respiration.

The researchers believe that activation of Caren in cardiomyocytes could lead to the development of new heart failure therapies. Heart failure is when reduced pumping function (contraction and ...
