The morphometric method is a way to demonstrate cell death in the laboratory. Morphometric measurement provides the result of cell death as a volume, size, weight and length of tissue, organ and the whole organism that compares with before and after the occurrence of cell death. [2]
Overview of signal transduction pathways involved in apoptosis. Cell death is the event of a biological cell ceasing to carry out its functions. This may be the result of the natural process of old cells dying and being replaced by new ones, as in programmed cell death, or may result from factors such as diseases, localized injury, or the death of the organism of which the cells are part.
Cell damage (also known as cell injury) is a variety of changes of stress that a cell suffers due to external as well as internal environmental changes. Amongst other causes, this can be due to physical, chemical, infectious, biological, nutritional or immunological factors.
The stalk is composed of dead cells that have undergone a type of PCD that shares many features of an autophagic cell-death: massive vacuoles forming inside cells, a degree of chromatin condensation, but no DNA fragmentation. [69] The structural role of the residues left by the dead cells is reminiscent of the products of PCD in plant tissue.
The ratio of potassium to sodium decreases linearly with time. The reason that the potassium levels rise after death is because of a leak in the cell membrane that allows the concentration to reach equilibrium with the potassium levels in the blood plasma. This method is not exact, but a good estimate for the time since death can be obtained. [2]

In cell biology, efferocytosis (from efferre, Latin for 'to carry out' [1] (to the grave), extended meaning 'to bury') is the process by which apoptotic cells are removed by phagocytic cells. It can be regarded as the 'burying of dead cells'.
