Researchers have developed an unlimited number of pure insulin-producing cells from mouse embryonic stem cells.

Changes To Embryonic Stem Cells Caused By Down Syndrome Revealed

admin — Mon, 08 Sep 2008 01:45:12 -0500

Scientists investigating the mechanisms of Down syndrome have revealed the earliest developmental changes in embryonic stem cells caused by an extra copy of human chromosome 21 -- the aberrant inheritance of which results in the condition.

Scientists have genetically programmed embryonic stem cells to become nerve cells when transplanted into the brain, according to a new study. The research, an important step toward developing new treatments for stroke, Alzheimer's, Parkinson's and other neurological conditions showed that mice afflicted by stroke showed therapeutic improvement following transplantation of these cells. None of the mice formed tumors, a major setback in prior attempts at stem cell transplantation.

Enzyme Plays Key Role In Cell Fate

The road to death or differentiation follows a similar course in embryonic stem cells according to new research in the journal Cell Stem Cell. Caspases, known as 'killer enzymes,' that are activated during programmed cell death, are also active in the initial phases of cell differentiation, according to researchers.

Tissue-specific Blood Stem Cell Line Established From Embryonic ...

Researchers in Sweden have established and isolated the tissue-specific stem cell that produces blood cells (blood stem cell) by using genetically modified embryonic stem cells.

Heart Derived Stem Cells Develop Into Heart Muscle

Researchers have succeeded in growing large numbers of stem cells from adult human hearts into new heart muscle cells. A breakthrough in stem cell research. Until now, it was necessary to use embryonic stem cells to make this happen.

Tissues derived from embryonic stem cells could help to pacify the immune system and so prevent recipients from rejecting them.

Earliest Step In Human Development Revealed By Human Embryonic S...

Researchers have uncovered the molecular underpinnings of one of the earliest steps in human development using human embryonic stem cells. Their identification of a critical signal mediated by the protein BMP-4 that drives the differentiation of stem cells into what will become the placenta, will be published in Cell Stem Cell. The finding, they say, also highlights one aspect of human cell biology that has not been replicated in other animal model systems.

Tissues derived from embryonic stem cells could help to pacify the immune system and so prevent recipients from rejecting them, the UK National Stem Cell Network Science Meeting will hear today (April 11).
