Web16 jun. 2024 · We show that intestinal cells can contain nuclear fat, particularly during high-low-high changes in cytoplasmic fat that involve de novo fat synthesis. Nuclear fat is associated with multiple changes in intestinal nuclei that appear to represent damage and repair. Germ nuclei that normally differentiate into oocytes can also contain nuclear fat.
WebCytoplasmic determinants are special molecules which play a very important role during oocyte maturation, in the female's ovary. During this period of time, some regions of the cytoplasm accumulate some of these cytoplasmic determinants, whose distribution is thus very heterogenic. They play a major role in the development of the embryo's organs. WebNECROSIS AND ITS TYPES. Definition- Necrosis refers to spectrum of morphologic changes that follow cell death in living tissue, largely resulting from the progressive degradative action of enzymes on lethally injured cell. The morphologic appearance of necrosis is the result of denaturation of intracellular proteins & enzymatic digestion of the ...
