Human endothelial cells, light micrograph
Human endothelial cells. Light micrograph of cultured human endothelial cells, a cell type found lining the blood vessels. Fluorescent dyes have been used to show the cell structures. Actin filaments are red, and the cell nuclei are blue. Some of the cell nuclei are in the process of dividing, aided by the actin. An early stage is at upper right. A later stage is at upper left and lower right, with the cell chromosomes (white) being pulled apart by the densely packed actin (red). Actin is the most abundant cellular protein, forming part of the cells' cytoskeleton. The cell nuclei contain the cells' genetic information, DNA (deoxyribonucleic acid) packaged in chromosomes. Magnification: x150 when printed at 10 centimetres wide.
