Heart cell. Fluorescence microscopy footage of a cultured neonatal heart cell (cardiomyocyte), showing calcium swirls (green) due to calcium sparking. This is a form of 'local control' where calcium ions are released by cardiac muscle cells. It is part of the process by which heart muscle contracts. This cell is being examined in culture. The calcium ion flux is made visible using a fluorescent probe. | |
