Pancreas cells. Fluorescent light micrograph of epithelial (lining) cells from the pancreas. DNA (deoxyribonucleic acid) in their nuclei is blue. The green strands are microtubules and the red strands are actin. These proteins make up their cytoskeletons. The cytoskeleton supports the cell and its organelles, including the mitochondria (not seen). Some of these cells (at far right, for instance) are in the process of cell division (mitosis). During this process copies of the genetic material are pulled to opposite sides of the cell, and the cell splits apart to form two identical daughter cells. Magnification: x1000 at 6x9cm size.
