Exercise increases brain growth factor and receptors, prevents stem cell drop in middle age (11/20/2008)

A new study confirms that exercise can reverse the age-related decline in the production of neural stem cells in the hippocampus of the mouse brain, and suggests that this happens because exercise restores a brain chemical which promotes the production and maturation of new stem cells. ...> Full Article

Simple chemical procedure augments therapeutic potential of stem cells (11/2/2008)

Researchers have developed a simple method for making a certain class of adult stem cells more therapeutically effective. By attaching a molecule called SLeX to the surface of human cells extracted from bone marrow, researchers have altered how the cells travel through vessels. This might enable the cells to more effectively reach sites of injury and replace damaged tissue. ...> Full Article

Spinning Natural Proteins Into Fabrics For New Wound-repair Products (10/22/2008)

Scientists in Israel are reporting the first successful spinning of a key natural protein into strong nano-sized fibers about 1/50,000th the width of a human hair. The advance could lead to a new generation of stronger, longer-lasting biocompatible sutures and bandages to treat wounds. ...> Full Article

Survey: Nearly 70 percent of public supports embryonic stem cell research (10/22/2008)

With both presidential candidates vowing to ease federal funding restrictions on embryonic stem cell research and important scientific advances reported widely in the media, a new University of Michigan study shows a majority of the public supports embryonic stem cell research. ...> Full Article

Stem Cell Breakthrough: Mass-Production Of 'Embryonic' Stem Cells From A Human Hair (10/20/2008)

The first reports of the successful reprogramming of adult human cells back into so-called induced pluripotent stem cells, which by all appearances looked and acted like embryonic stem cells, created a media stir. But the process was woefully inefficient: Only one out of 10,000 cells could be persuaded to turn back the clock. ...> Full Article

Fat-regenerating 'stem cells' found in mice (10/12/2008)

Researchers have identified stem cells with the capacity to build fat. Although they have yet to show that the cells can renew themselves, transplants of the progenitor cells isolated from the fat tissue of normal mice can restore normal fat tissue in animals that are otherwise lacking it. ...> Full Article

Scientists pinpoint key proteins in blood stem cell replication (10/10/2008)

A family of cancer-fighting molecules helps blood stem cells in mice decide when and how to divide, say researchers at the Stanford University School of Medicine. Blocking the molecules' function spurs the normally resting cells to begin proliferating strangely - making too much of one kind of cell and not enough of another. Many types of human blood cancers involve a similar disruption in the expression of that same family of molecules. ...> Full Article
