Apoptosis. Transmission electron micrograph (TEM) of a section through human myeloid white blood cells (leucocytes, black nuclei) undergoing apoptosis. Healthy myeloid cells can also be seen. Apoptosis is the process of genetically programmed cell death. The apoptotic cells no longer have the typical protuberances from their cell surfaces and their nuclei are breaking down. Myeloid cells, which are found in the bone marrow, are the precursors for many types of leucocyte. Myeloid cells undergo apoptosis if they are deprived of growth factors. Research on apoptosis may provide genetic treatments for diseases like cancer. Magnification: x6200 at 7x8.5 inch size.
