   Cells dying by apoptosis

The electron micrograph shows an apoptotic cell in the mammary gland. Apoptotic cell death is a normal occurrence here, balancing the proliferation of mammary epithelial cells that occurs in each menstrual cycle. Note the disintegrating nuclear envelope and the dark clumps of condensed chromatin. For comparison, part of a normal cell is visible to one side of the picture. (Courtesy of David Ferguson.)
