Cell division. Confocal light micrograph of a HeLa cell during cytokinesis (cell division). Cytokinesis occurs after nuclear division (mitosis),which produces two daughter nuclei (yellow) from one parent nuclei. A contractile ring made of actin filaments (green) forms beneath the cell's plasma membrane. This contracts,creating a furrow in the cytoplasm. The furrow deepens,separating the cytoplasm and cell organelles (such as mitochondria,red),until the two new cells are formed. HeLa cells are a continuously cultured cell line of human cancer cells. They are immortal and so thrive in the laboratory. HeLa cells are widely used in biological and medical research | |
