Lung cells. Confocal laser scanning micrograph of bovine pulmonary artery epithelial cells. The cell nuclei, which contain the cells' genetic information, are blue. Actin filaments are green. Actin forms part of the cytoskeleton, which maintains the cells' shape, allows some cellular mobility and is involved in intracellular transport. Mitochondria, which produce energy for the cell, are red. Bovine pulmonary artery epithelial cells.
