Apoptosis: Dance of Death - Cells Alive

Los Angeles, California - United States

Human neutrophils are constantly produced in the marrow and released into the blood to search for invading pathogens. Apoptosis AnimationAfter only one day, they "commit suicide" and are replaced by younger cells. Beginning with the typical neutrophil shape, the apoptotic neutrophil in the clip above undergoes a series of changes including violent membrane blebbing, called zeiosis, (animation to the right) and fragmentation of DNA creating a vacuolar nucleus. Apoptotic cells shrink in size, break into smaller pieces called apoptotic bodies that other body cells recognize and eat.

During development from stem to fully differentiated, cells in the body alternately divide (mitosis) and "appear" to be resting (interphase). This sequence of activities exhibited by cells is called the cell cycle. Interphase, which appears to the eye to be a resting stage between cell divisions, is actually a period of diverse activities. Those interphase activities are indispensible in making the next mitosis possible.

This animation demonstrates the stages of mitosis in an animal cell. Use the control buttons in the upper left to run the complete animation. Events during Mitosis Interphase: Cells may appear inactive during this stage, but they are quite the opposite. This is the longest period of the complete cell cycle during which DNA replicates, the centrioles divide, and proteins are actively produced. For a complete description of the events during
