Caption: Apoptosis. Scanning Electron Micrograph (SEM) of human white blood cells (leucocytes), showing one cell undergoing apoptosis. Apoptosis is the process of "genetically programmed cell death". At upper right, an apoptotic white blood cell has shrunk & its cytoplasm has developed blebs (grape- like clusters). Normal white blood cells are seen beside it. These white blood cells are myeloid leucocytes, originating from bone marrow. The human myeloid cell line depends on growth factors to survive, and cells undergo apoptosis when deprived of growth factors. Research on apoptosis may provide genetic treatments for diseases such as cancer. Magnification: x7,500 at 8x10inch size.
