Sentences with phrase «single type of stem cell»

It was thought that different layers of neurons are generated in successive waves by a single type of stem cell.

Not exact matches

Embryonic stem cells are scientifically and medically interesting because they are «pluripotent» (capable of generating many cell types), but they are not the same as totipotent single - cell embryos.

«Just as normal cells with the same genome differentiate into many different cell types, a single tumor characterized by specific genetic mutations can contain many different types of cells — stem - like and more differentiated cells — with the difference being rooted in their epigenetic information.

The results help fill in the scientific puzzle kicked off by Dolly's cloning, which proved that mammalian egg cells were capable of dissolving the genetic roadblocks that limit the potential of most adult cells to give rise to only a single type of tissue — that of the organ from which they hail — whereas embryonic stem cells have the potential to become virtually any kind of body tissue.

But how the production of daughter cells from the different stem cell types is coordinated within a single niche is virtually unknown.

In a matter of weeks, the single stem cell repopulated the mouse's blood and immune system but did not create other types of cells.

\ n \ nWhile historically there had been a ban on taxpayer funding of embryonic stem cell research, there has never been a ban on private funding in this country and many European countries have allowed this type of research for years, but so far none of this research has yielded a single therapeutic use.

The collection of protocols includes the isolation and maintenance of stem cells from various species using «conventional» and novel methods, such as derivation of ES cells from single blastomeres, differentiation of stem cells into specific tissue types, isolation and maintenance of somatic stem cells, stem cell - specific techniques and approaches to tissue engineering using stem cell derivatives.

By turning on a single gene, researchers can prevent skin stem cells from maturing into the three types of adult skin cells — epidermal, sebaceous and hair cells.
