Pyknosis, or the irreversible nuclear condensation (a nuclear morphology) in a cell (generally old vertebrate leukocyte cells) is the result of a cell undergoing either apoptosis or necrosis. [3] . …

The meaning of PYKNOSIS is a degenerative condition of a cell nucleus marked by clumping of the chromosomes, hyperchromatism, and shrinking of the nucleus.

So…the bottom line is that pyknosis is a nuclear change in which the nucleus shrinks and becomes dark blue/black. Typically, we associate the word “pyknosis” with necrotic cells – but …

Pyknosis occurs in senescent (old) leukocytes and results from preprogrammed cell death (apoptosis). With pyknosis, the nucleus becomes dense and compact and begins to fragment …

Pyknosis, a classis sign of apoptosis, also occurs, resulting from condensation of chromatin. Histological staining usually shows single cells or small clusters or cells. Subcellular changes …

A thickening or condensation; specifically, a condensation and reduction in the size of the cell or its nucleus, usually associated with hyperchromatosis; nuclear pyknosis is a stage of necrosis. …

1999年4月10日 · Intense nuclear condensation with intense refractivity (pyknosis) is the ubiquitous terminus of all apoptosis and some necrosis of vertebrate cells, but its structural …
