Watch as living cells undergo the process of apoptosis, a type of programmed cell death. Apoptosis in these cultured cartilage cells was induced by treatment with phosphate. Images were collected every 10 minutes for 20 hours using differential interference contrast microscopy. Notice how the cells shrink and become lobed, a change called blebbing. The cells form apoptotic bodies as the internal contents of the cell are degraded. Credit: Cristina Teixeira, New York University College of Dentistry
