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

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

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
