Test may predict cancer response to anemia drugs

June 1, 2008 | Categories: Research | Tagged: , ,

A genetic test may help predict whether giving cancer patients anemia drugs could make their cancer worse, U.S. researchers said on Sunday. Over the past year and a half, eight late-stage clinical trials have shown that treatment with drugs known as erythropoiesis-stimulating agents, or ESAs, can have an adverse impact on cancer survival, the study’s […] Read More

Stem-cell breakthrough may help UW researchers

November 21, 2007 | Categories: Research | Tagged: , ,

A new method for creating embryonic stem cells would put a host of research projects on a fast track at the University of Washington, where scientists have been limited by aging embryonic stem-cell lines that have been fading as if they’d been “through generations of photocopying.” At the UW’s Institute for Stem Cell and Regenerative […] Read More

US: Keeping stem cell research alive

October 21, 2007 | Categories: Research | Tagged: ,

In an era of reduced federal funding in America for medical research, scientists at the University of Washington (UW) in Seattle were thrilled to receive a $10 million grant from the National Institutes of Health (NIH) – the nation’s premier medical research agency. The grant will fund stem cell research over the next five years. […] Read More

Researchers were able to use human-derived stem cells to grow a heart muscle graft (bottom) in a rat heart damaged by a heart attack. The human-derived cells incorporated with scar tissue (middle) and regular heart muscle cells (top).

Human derived stem cells can repair rat hearts damaged by heart attack

August 27, 2007 | Categories: Research | Tagged: , , ,

When human heart muscle cells derived from embryonic stem cells are implanted into a rat after a heart attack, they can help rebuild the animal’s heart muscle and improve function of the organ, scientists report in the September issue of Nature Biotechnology. The researchers also developed a new process that greatly improves how stem cells […] Read More

Stem-Cell Procedure Could Rebuild Heart Tissue

August 26, 2007 | Categories: Research | Tagged:

Heart muscle doesn’t regenerate when it’s damaged, one reason heart attacks are so debilitating. A dream of researchers is to build new heart muscle using transplanted cardiac stem cells. Scientists at the University of Washington have taken a potentially important step in that direction, using embryonic stem cells as their starting material. Scientists haven’t made […] Read More

Stem cells proved effective in regrowing heart muscle in rats

| Categories: Research | Tagged: , ,

Human embryonic stem cells have been used to regrow the heart muscles of rats that had survived lab-induced heart attacks, scientists from the University of Washington and a private biotechnology company reported today. Because the rebuilt heart muscle halted the progression of heart failure, the findings offer encouragement that treatments based on embryonic stem cells […] Read More

How Does A Zebrafish Grow A New Tail? The Answer May Help Treat Human Injuries

December 28, 2006 | Categories: Research | Tagged: , ,

If a zebrafish loses a chunk of its tail fin, it’ll grow back within a week. Like lizards, newts, and frogs, a zebrafish can replace surprisingly complex body parts. A tail fin, for example, has many different types of cells and is a very intricate structure. It is the fish version of an arm or leg. […] Read More

Over-activation of a signaling pathway leads to an enlarged niche and over-production of stem cells. Red marks the niche cells

Stem Cells Engage In Dialogue With The Cells That Regulate Their Futures

November 6, 2006 | Categories: Research | Tagged: , ,

Dialogue, not a monologue, is the basis of all good communication. Stem cells are no exception. Recent University of Washington (UW) research has found an early indication of two-way cellular communication in the miniscule niches of the body where the futures of stem cells are determined. Stem cells require these niches – nest-like microenvironments made […] Read More

Repairing the retina: Stem-cell procedure promising

August 15, 2006 | Categories: Research | Tagged: , ,

Procedures using stem cells derived from human embryos could be utilized in a few years to repair disease-damaged retinas, new research by University of Washington scientists indicates. UW scientists reported Monday that they have successfully used the stem cells to treat diseased tissue in mouse retinas, a key portion of the eye. “This is a […] Read More

Region has right stuff to be leader in stem cells

March 16, 2006 | Categories: Research | Tagged: ,

One legacy of modern medicine’s success is that our society has grown older. As an inevitable consequence, every person will eventually suffer from, or will know someone who suffers from, a debilitating disease. With that bleak prospect looming as a certainty, a revolution in medicine, organized under the broad banner of regenerative medicine, is seeking […] Read More
