Then we take one of the horse's preserved cells, insert it into the egg and fuse them in a process that imitates fertilization?the sperm hitting the egg. (practicalhorsemanmag.com)
Additionally, the sperm from the male patient or a sperm donor is prepared through a process called "sperm washing," which isolates healthy sperm from the remainder of the seminal fluid to improve chances of fertilization. (extendfertility.com)
Homologous recombination is widely used by cells to precisely repair damaged DNA breaks that occur on both DNA strands, known as double-strand breaks (DSBs), in a process called homologous recombination repair (HRR). (oldfield.info)
Homologous recombination also produces new combinations of DNA sequences during meiosis, the process by which eukaryotes make gamete cells, such as sperm and egg in animals. (oldfield.info)

To take human organ generation via BC and transplantation to the next step, we reviewed current emerging organ generation technologies and the associated efficiency of chimera formation in human cells from the standpoint of developmental biology. (frontiersin.org)

Each cell in the human body contains genetic material that carries the instructions for every protein, cell, and organ that makes up the body. (primaryimmune.org)
During meiosis, homologous recombination can produce new combinations of ges as below between similar, but not identical, copies of human chromosome 1. (oldfield.info)

They have the ability to divide and make an indefinite number of copies of themselves. (healthline.com)
They make new red blood cells, white blood cells, and other types of blood cells. (healthline.com)
Choosing at least two donors is mandatory to make sure that the test is performed randomly. (europeanspermbank.com)

In the US, for example, a woman from Mississippi, Victoria Gray, has had bone marrow cells removed, genetically modified, and then returned to her body so that instead of producing the unusually formed red blood cells that give sickle cell disease its name, they create haemoglobin to deliver her from incapacitating bouts of pain. (afr.com)
Cell competition also has pathological consequences, and can create super-competitor cells responsible for tumor progression. (bvsalud.org)

a type of biological diversity that is exhibited in the variety of structural forms in living things, from internal cell structure to body morphology. (edrawmind.com)
This means they're capable of developing into cells that serve numerous functions in different parts of the body. (healthline.com)
Most cells in the body are differentiated cells. (healthline.com)
Eventually, the cells begin to differentiate, taking on a certain function in a part of the body. (healthline.com)
These cells can give rise to virtually any other type of cell in the body. (healthline.com)
However, if we think back to what actually happened to the animal - it died, even if from the cold, the cells in the body would have taken some time to freeze. (wikiquote.org)
