Heart tissue. Fluorescence deconvolution micrograph of a section through heart tissue. The heart largely consists of fibres (red) of cardiac muscle (the myocardium) that contract to pump blood around the heart. This tissue sample includes small intramyocardial vessels. Cellular proteins are highlighted with fluorescent markers: g-actin (red), smooth muscle actin (green) and cell nuclei (blue).
