Heart tissue. Fluorescence deconvolution micrograph of a section through heart tissue. The heart largely consists of fibres (green) of cardiac muscle (the myocardium) that contract to pump blood around the heart. This high-power magnification shows intercalated discs (orange) and muscle striations. Cellular proteins are highlighted with fluorescent markers: g-actin (red), f-actin (green) and cell nuclei (blue).
