At the top of the list comes the zygote-a fertilized egg, which of course has the ability to divide and differentiate into all cell types in the body and create a new organism. (thefutureofthings.com)
As the embryonic cells divide and the daughter cells differentiate, they become increasingly specific. (thefutureofthings.com)
Stem cells have two unique characteristics: (1) an almost unlimited capacity for self-renewal (they can theoretically divide without limit to replenish other cells for as long as the person is alive) and (2) they retain the potential to produce differentiated and specialized cell types. (erlc.com)
Tissue regeneration occurs due to the proliferation of stem cells, which can not only divide, but also differentiate into cells of the tissue whose regeneration is taking place. (vechnayamolodost.ru)
It is not surprising that vertebrates have significantly higher life expectancy than invertebrates - the same insects whose cells do not divide in adulthood. (vechnayamolodost.ru)

All organisms begin from a single cell. (cusabio.com)
No matter how simple or complex an organism is, the cell remains the structurally and functionally basic unit of life (there are even unicellular organisms, like bacteria. (orthodoxwiki.org)
As organisms develop, stem cells become specialized types of cells. (orthodoxwiki.org)

One cloning technology that has been developed for mammalian and human cells is somatic cell nuclear transfer (SCNT). (news-medical.net)

For many decades, stem cells have played an important role in medical research, beginning in 1868 when Ernst Haeckel first used the phrase to describe the fertilized egg which eventually gestates into an organism. (wikipedia.org)
SCNT refers to a process that entails transferring somatic cells of an existing organism into the oocyte where the nucleus came from (National Human Genome Research Institute Para 1). (premiumessays.net)

The JNK signaling pathway can affect a variety of life processes such as cell growth, cell differentiation, and cell death. (cusabio.com)
First, stem cells provide a valuable tool for studying both normal and abnormal cellular processes. (erlc.com)
Therefore, it is important to understand how and when aberrancies such as the epigenetic instability of the X chromosome arise, and to define their consequences for differentiation processes and the differentiated progeny. (ca.gov)
