Adult stem cells activated in mammalian brain

1 vote

Adult stem cells originate in a different part of the brain than is commonly believed, and with proper stimulation they can produce new brain cells to replace those lost to disease or injury, a study by UC Irvine scientists has shown. Evidence strongly shows that the true stem cells in the mammalian brain are the ependymal cells that line the ventricles in the brain and spinal cord...

♦ Purified stem cells restore muscle in mice with muscular dystrophy

1 vote

By injecting purified stem cells isolated from adult skeletal muscle, researchers have shown they can restore healthy muscle and improve muscle function in mice with a form of muscular dystrophy. Those muscle-building stem cells were derived from a larger pool of so-called satellite cells that normally associate with mature muscle fibers and play a role in muscle growth and repair.

♦ How Vitamin A Promotes Cancer Growth ?

1 vote

The researchers found that vitamin A, when applied to breast cancer cells, triggers genes that can push stem cells embedded in a tumour to morph into endothelial cells. These cells can then build blood vessels to link up to the body's blood supply, promoting further tumour growth. They showed that in cancer cells, vitamin A seems to turn on cancer stem cells...

♦ Stem Cells May Treat Muscular Dystrophy

1 vote

The researchers have revealed that they derived the muscle-building stem cells from a larger pool of so-called satellite cells, which normally associate with mature muscle fibres and play a role in muscle growth and repair. They say that besides their contributions to mature muscle, the injected cells also replenished the pool of regenerative cells normally found in muscle. According to them...

♦ Researchers Map Cells' Inner Landscapes

1 vote

ScienceDaily (July 10, 2008) Much of the field of stem cell biology and development remains uncharted territory. Just as famous explorers and astronomers mapped out landmasses and constellations, researchers are working fervently to chart the molecular landscapes within stem cells especially embryonic stem cells. A clearer understanding of the cells unique properties... Submitted by: fhassan - Visited 5 - Comments 0 - Write first comment

♦ Adult Stem Cells Reprogrammed In Their Natural Environment

ScienceDaily (June 23, 2008) — Researchers at Children's Hospital Boston are continuing to document the heart's earliest origins. Now, they have pinpointed a new, previously unrecognized group of stem cells that give rise to cardiomyocytes, or heart muscle cells. These stem cells, located in the surface of the heart, or epicardium... Submitted by: koahost - Visited 4 - Comments 0 - Write first comment

♦ U-M study: Herceptin targets breast cancer stem cells

1 vote	ANN ARBOR, Mich. A gene that is overexpressed in 20 percent of breast cancers increases the number of cancer stem cells, the cells that fuel a tumor's growth and spread, according to a new study from the University of Michigan Comprehensive Cancer Center. The gene, HER2, causes cancer stem cells to multiply and spread... Submitted by: bstunt - Visited 9 - Comments 0 - Write first comment

♦ Exhausted B cells hamper immune response to HIV

1 vote

Recent studies have shown that HIV causes a vigorous and prolonged immune response that eventually leads to the exhaustion of key immune system cells--CD4+ and CD8+ T-cells--that target HIV. These tired cells become less and less able to fight the virus, and the cells' fatigue contributes to the inability of an HIV-infected person's immune system to clear the virus from the body. Now...
