Fluorescent light microscopy of cultured human cancer cells showing one undergoing mitosis (nuclear division) and cytokinesis (cell division). Mitosis is the formation of two daughter nuclei from one parent nucleus. Fluorescent markers have been used to highlight DNA (deoxyribonucleic acid, pink) and alpha tubulin (green), a component of microtubules. The cycle is first seen in interphase with its nucleus clearly visible. At prophase, the nuclear envelope dissolves and the chromosomes condense. The cell progress through prometaphase to metaphase, where the chromosomes align along the centre of the cell. The chromosomes start to move to the opposite poles, guided by microtubules, during anaphase. The last stage of mitosis is telophase, when the separated chromosomes have moved to opposite ends of the cell and two new nuclei form around them. Cytokinesis divides the cytoplasm of the cell in two, separating the cells. Filmed over 5 days.

Doctors operate on a cancer patient at the New England Deaconess Hospital, in Boston. Cancerous tissue excised from patient's body during surgery is saved to test behavior of the cells when exposed to radiation. The tissues are cultivated and then.examined under microscopes fitted with a movie camera. Cells divide. Radioactive material in a pack with warning, 'Hazard' written on it. A doctor exposes cancerous tissue to the radioactive material. Cancer cells die after exposure. Exterior view of the White Plains Hospital building in White Plains New York. A child runs to a woman in front of the hospital building. She picks up the child and both smile. Location: Boston Massachusetts USA. Date: 1957.

MITOSIS

Fluorescent light microscopy of a cultured human cancer cell undergoing mitosis (nuclear division) and cytokinesis (cell division) to form many cells. Mitosis is the formation of two daughter nuclei from one parent nucleus. Fluorescent markers have been used to highlight DNA (deoxyribonucleic acid, pink) and alpha tubulin (green), a component of microtubules. The cycle is first seen in interphase with its nucleus clearly visible. At prophase, the nuclear envelope dissolves and the chromosomes condense. The cell progress through prometaphase to metaphase, where the chromosomes align along the centre of the cell. The chromosomes start to move to the opposite poles, guided by microtubules, during anaphase. The last stage of mitosis is telophase, when the separated chromosomes have moved to opposite ends of the cell and two new nuclei form around them. Cytokinesis divides the cytoplasm of the cell in two, separating the cells. Filmed over 10 days.

Highly informative cartoon depiction of how normal cells in the human body (depicted as happy little workmen) work together and how cancer cells (scary looking black monsters) multiply and steal food from the healthy cells.
