Heart muscle cells,fluorescence deconvolution micrograph. Fluorescent dyes have been used to highlight cellular structures and proteins: cell nuclei (blue),cardiac actin (green),IP3 receptors (red). Actin is a contractile muscle protein. IP3 receptors are calcium channels. Muscle cell contraction is triggered by rising calcium levels,channelled through receptors like these,and in this case triggering the beating of the heart | |
