Breakthrough in Organ Rejection Diagnosis Examines Gene Behavior (11/25/2007)

New Research describes a revolutionary technique for more clearly identifying the possibility of organ rejection in kidney transplants. The technique, which uses a microarray or "Gene Chip," a process of examining DNA sequences, defines how major causes of organ disease leading to rejection share similar disturbances in gene behavior. The study is the first to show how gene sets, as opposed to single genes, can be used for diagnosis of rejection in individual patients, and offers new insight into the mechanisms of these gene changes. ...> Full Article

Imaging Neural Progenitor Cells In The Living Human Brain (11/18/2007)

For the first time, investigators have identified a way to detect neural progenitor cells (NPCs), which can develop into neurons and other nervous system cells, in the living human brain using a type of imaging called magnetic resonance spectroscopy (MRS). The finding may lead to improved diagnosis and treatment for depression, Parkinson's disease, brain tumors, and a host of other disorders. ...> Full Article

Team of Scientists Develops Non-Invasive Method to Track Nerve-Cell Development in Live Human Brain (11/10/2007)

A team of scientists have identified and validated the first biomarker that permits neural stem and progenitor cells (NPCs) to be tracked, non-invasively, in the brains of living human subjects. This important advance could lead to significantly better diagnosis and monitoring of brain tumors and a range of serious neurological and psychiatric disorders. ...> Full Article

Adult stem cells lack key regulator (10/24/2007)

The protein Oct4 plays a major role in embryonic stem cells, acting as a master regulator of the genes that keep the cells in an undifferentiated state. Unsurprisingly, researchers studying adult stem cells have long suspected that Oct4 also is critical in allowing these cells to remain undifferentiated. Indeed, more than 50 studies have reported finding Oct4 activity in adult stem cells. ...> Full Article

Stem Cell Nuclei Are Soft 'Hard Drives,' Study Finds (10/15/2007)

Biophysicists have discovered that the nuclei of human stem cells are particularly soft and flexible, rather than hard, making it easier for stem cells to migrate through the body and to adopt different shapes, but ultimately to put human genes in the correct nuclear "sector" for proper access and expression. ...> Full Article
