Researchers Find Culprit In Aging Muscles That Heal Poorly (8/12/2007)

Communication is critical. Garbled in, garbled out, so to (mis-)speak. Workers who get incomplete instructions produce an incomplete product, and that's exactly what happens with the stem cells in our aging muscles, according to researchers from the Stanford University School of Medicine. ...> Full Article

Scientists Seek Test To Detect Gene Doping In Athletes (8/8/2007)

Gene doping has the potential to spawn athletes capable of out-running, out-jumping and out-cycling the strongest of champions. But research under way at the University of Florida could help level the playing field by detecting the first cases of gene doping in professional athletes before the practice enters the mainstream. ...> Full Article

Gene Therapy: Identifying Where Genes Can Successfully Integrate (8/7/2007)

Gene therapy -- whereby a retrovirus that integrates into the genome of a treated patient is used to deliver the gene of interest -- has been used to treat some individuals with inherited diseases such as X-linked SCID, a disease that causes widespread immunosuppression and therefore susceptibility to infection. ...> Full Article

Not All Embryonic Stem Cell Lines Are Created Equal (8/7/2007)

When it comes to generating neurons, researchers have found that not all embryonic stem (ES) cell lines are equal. In comparing neurons generated from two NIH-approved embryonic stem cell lines, scientists have uncovered significant differences in the mature, functioning neurons generated from each line. The discovery implies that culture conditions during ES cell generation - which have yet to be identified - can influence the developmental properties of human ES cells. ...> Full Article

Cell Damage Caused By Brushing May Help Keep Gums Healthy (8/6/2007)

Initial Trigger Is Not Enough To Determine A Stem Cell's Fate (8/5/2007)

Disturbing a stem cell from its initial quiescent state was once thought to taint its gold-standard properties. However, research uncovering how a signaling pathway regulates stem cell behavior reveals that stem cells, once activated, enter a window of time during which they respond to their environment and retain their ability to alter their developmental path. ...> Full Article

Effects Of Aging In Stem Cells (7/31/2007)

There is little disagreement that the body's maintenance and repair systems deteriorate with age, even as there is plenty of disagreement as to why. Stem cells combat the aging process by replenishing old or damaged cells--particularly in the skin, gut, and blood--with a fresh supply to maintain and repair tissue. ...> Full Article

Team Identifies Gene That Regulates Blood-Forming Fetal Stem Cells (7/30/2007)

In the rancorous public debate over federal research funding, stem cells are generally assigned to one of two categories: embryonic or adult. But that's a false dichotomy and an oversimplification. A new University of Michigan study adds to mounting evidence that stem cells in the developing fetus are distinct from both embryonic and adult stem cells. ...> Full Article

Critical Protein Distinguishes Fetal and Adult Stem Cells (7/28/2007)

In a discovery that fills a critical gap in the understanding of stem cells, researchers have discovered a protein that fetal, but not adult, blood-forming stem cells need to replenish themselves. Finding regulatory pathways specific to fetal blood-forming cells could help scientists understand childhood leukemias and generate blood-forming cells for bone marrow transplants, said the researchers. ...> Full Article

Gene-Transcription Machinery Seen Poised for Action, May Provide Insights into Stem-Cell Differentiation (7/26/2007)

For some time, scientists have been tracking down the sequence of biochemical steps required to attract and assemble at the head end of a gene the molecular machinery needed to transcribe that gene to put to work the information it encodes. Now, a new study led by researchers at The Wistar Institute suggests that the gene-transcription machinery, once in place, can remain poised for action but held in check until a triggering signal sends it on its way down the linear DNA molecule. ...> Full Article
