Overview

Necrosis, apoptosis, and autophagic cell death are all manners in which cells can die, and these mechanisms can be induced by different stimuli, such as cell injury, low nutrient levels, or signaling proteins. Whereas necrosis is considered to be an “accidental” or unexpected form of cell death, evidence exists that apoptosis and autophagy are both programmed and “planned” by cells.

In this introductory video, JoVE highlights key discoveries pertaining to cell death, including recent work done in worms that helped identify genes involved in apoptosis. We then explore questions asked by scientists studying cell death, some of which look at different death pathways and their interactions. Finally, several methods to assess cell death are discussed, and we note how researchers are applying these techniques in their experiments today.

Procedure

Paradoxically, cell death helps shape an organism’s life. Just like any whole organism, cells can die as a result of aging, due to accidental injury, or following a pathogen infiltration a cell can sacrifice itself to prevent the spread of infection. Under these circumstances, cells can follow different death pathways like apoptosis, autophagy, or necrosis. All these types display specific morphological characteristics. Apoptosis or programmed cell death leads to membrane “blebbing” and nuclear fragmentat…
