In the context of microbiology, enucleation refers to removing the nucleus of a cell and replacing it with a different nucleus. This is used mainly in cloning but can also be used for creating hybrids of plants or animals. It was discovered that cells can be chemically enucleated with Cytochalasin B in 1967. [1]
A nucleated red blood cell (NRBC), also known by several other names, is a red blood cell that contains a cell nucleus. Almost all vertebrate organisms have hemoglobin -containing cells in their blood, and with the exception of mammals , all of these red blood cells are nucleated. [ 1 ]
A father providing a sperm cell, one mother providing the egg nucleus, and another mother providing the enucleated egg cell. [ 15 ] In 2018, the first successful cloning of primates using somatic cell nuclear transfer, the same method as Dolly the sheep , with the birth of two live female clones ( crab-eating macaques named Zhong Zhong and Hua ...
The cell nucleus (from Latin nucleus or nuculeus 'kernel, seed'; pl.: nuclei) is a membrane-bound organelle found in eukaryotic cells.Eukaryotic cells usually have a single nucleus, but a few cell types, such as mammalian red blood cells, have no nuclei, and a few others including osteoclasts have many.
Red blood cells (RBCs), referred to as erythrocytes (from Ancient Greek erythros 'red' and kytos 'hollow vessel', with -cyte translated as 'cell' in modern usage) in academia and medical publishing, also known as red cells, [1] erythroid cells, and rarely haematids, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O 2) to the body tissues—via ...
Enucleation may refer to: . Enucleation (surgery), the removal of a mass without cutting into or dissecting it Enucleation of the eye, removal of the eye that leaves the eye muscles and remaining orbital contents intact
In the process of maturation, a basophilic pronormoblast is converted from a cell with a large nucleus and a volume of 900 fL to an enucleated disc with a volume of 95 fL. By the reticulocyte stage, the cell has extruded its nucleus, but is still capable of producing hemoglobin.
Structurally, they are elongated and parallel to the organ or tissue that they are located in. Sieve elements typically lack a nucleus and contain none to a very small number of ribosomes. [2] The two types of sieve elements, sieve tube members and sieve cells, have different structures.
