On the other hand, the problem is, you know, with embryonic stem cells, they haven't been able to get stem cell lines from livestock animals that can proliferate in that way, without just sort of veering up in their own direction and turning into, instead of muscle, turning into brain tissue or bone tissue or something else.

Organlike tissue bits can be generated from pluripotent stem cells that are either plucked from embryos or created by taking a person's adult skin or blood cells and chemically inducing them to revert to an embryonic - like state.

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.

Previous research in rodent disease models has shown that transplanted oligodendrocyte precursor cells derived from embryonic stem cells and from human fetal brain tissue can successfully create myelin sheaths around nerve cells, sometimes leading to dramatic improvements in symptoms.

This has always been a worry with tissues produced from embryonic stem cells, as these have the capability to form tumours if any are left in their original state in the transplanted tissue.

The research used skin samples from five men to create what are known as induced pluripotent stem cells, which closely resemble embryonic stem cells in their ability to become nearly any tissue in the body.

A human embryonic stem cell is reined in — prevented from giving up its unique characteristics of self - renewal and pluripotency — by the presence of a protein modification that stifles any genes that would prematurely instruct the cell to develop into heart or other specialized tissue.

iPSCs are cells that were originally from adult tissues, but have been forced to produce proteins that are thought to be essential for the pluripotency of human embryonic stem cells.
