Scientists discover stem cell trigger
Source: The Times
Date: October 30, 2005
Summary:
The Times reports on the discovery of a chemical trigger that coaxes embryonic stem cells to develop into organs:
"Scientists have made a breakthrough in cell research that they believe brings the prospect of drastic improvements in the treatment of diseases such as Parkinson’s and multiple sclerosis. They have discovered the chemical trigger that causes stem cells from embryos to start developing into organs, raising the possibility of parts of the body being able to repair their own damage."

Stem cells turned into organ precursors
Source: Source: United Press International
Date: October 28, 2005
Summary:
Scientists said they have for the first time turned embryonic stem cells in the lab into a type of cell that can give rise to several internal organs, including the pancreas, liver and lungs. The advance is seen as a breakthrough that will enable scientists eventually to use the stem cells to repair diseased or damaged tissue. It likely also will facilitate the use of the cells for studying how diseases originate, which could lead to insights about cures and treatments.

Summary:
UCSF scientists have illuminated a key step in a signaling pathway that helps orchestrate embryonic development. The finding, they say, could lead to insights into the development of stem cells, as well as birth defects and cancers, and thus fuel therapeutic strategies.

Stem Cells' Electric Abilities Might Help Their Safe Clinical Use
Source: Johns Hopkins Medical Institutions
Posted: October 20, 2005
Summary:
Researchers from Johns Hopkins have discovered the presence of functional ion channels in human embryonic stem cells (ESCs). These ion channels act like electrical wires and permit ESCs, versatile cells that possess the unique ability to become all cell types of the body, to conduct and pass along electric currents. If researchers could selectively block some of these channels in implanted cells, derived from stem cells, they may be able to prevent potential tumor development.

Stem Cell Breakthrough: Researchers Offer Proof-of-concept For Altered Nuclear Transfer
Source: Whitehead Institute for Biomedical Research
Posted: October 17, 2005
Summary:
Scientists at Whitehead Institute for Biomedical Research have successfully demonstrated that a theoretical--and controversial--technique for generating embryonic stem cells is indeed possible, at least in mice. The theory, called altered nuclear transfer (ANT), proposes that researchers first create genetically altered embryos that are unable to implant in a uterus, and then extract stem cells from these embryos. Because the embryos cannot implant, they are by definition not "potential" human lives.

Neural Stem Cells Are Long-lived
Source: Howard Hughes Medical Institute
Date: October 6, 2005
Summary
New studies in mice have shown that immature stem cells that proliferate to form brain tissues can function for at least a year -- most of the life span of a mouse -- and give rise to multiple types of neural cells, not just neurons. The discovery may bode well for the use of these neural stem cells to regenerate brain tissue lost to injury or disease.

Stem cell hope for liver patients
Source: The Scotsman
Date: 6 October 2005
Summary:
PATIENTS with liver failure have been successfully treated using their own bone marrow stem cells. Doctors extracted the stem cells from the patients' blood. They were then injected back into blood vessels connected to the liver. The stem cells appear to home in on damaged areas of the liver and make repairs, although the process involved is not yet fully understood.

Summary:
High levels of a stem cell subtype called endothelial progenitor cells (EPCs) in the blood may improve the survival rate of people with acute lung injury, a deadly form of lung failure. The findings appear in the October issue of the American Journal of Respiratory and Critical Care Medicine.
