(PhysOrg.com) -- Initial results from a large, randomized clinical trial for patients with multiple myeloma, a cancer of the blood and bone marrow, showed that patients who received the oral drug lenalidomide (Revlimid, also known as CC-5013) following a blood stem cell transplant had their cancer kept in check longer than patients who received a placebo. http://www.physorg.com/news180631466.html Medicine & Health Mon, 21 Dec 2009 15:40:03 EST news180631466 Cholesterol-lowering drugs known as statins are among the most prescribed medicines in the U.S. Now a new study by researchers at Fred Hutchinson Cancer Research Center indicates that statins may protect stem cell transplant patients from one of the most serious complications of the life-saving cancer therapy: graft-versus-host disease, or GVHD. The findings are reported in the Nov. 4 first edition of the journal Blood. http://www.physorg.com/news179165432.html Medicine & Health Fri, 04 Dec 2009 16:11:40 EST news179165432 (PhysOrg.com) -- Researchers say a new development in cord blood transplants for inherited metabolic disorders may be curative for some babies who are treated while still in the womb. http://www.physorg.com/news174670072.html Medicine & Health Tue, 13 Oct 2009 16:50:02 EST news174670072 (PhysOrg.com) -- Researchers at the University of Toronto have developed a new model that explains how cells communicate and specifically reveals how blood cells "talk" to each other. The result could help transform treatments for diseases such as leukemia. http://www.physorg.com/news168702550.html Biology Wed, 05 Aug 2009 15:00:01 EST news168702550 When Jennifer Garcia scheduled the birth of her daughter at South Miami Hospital, nurses asked her an unusual question: "After your baby is born, are you willing to donate the umbilical cord to save someone's life?" http://www.physorg.com/news163334467.html Medicine & Health Thu, 04 Jun 2009 11:41:38 EST news163334467 University of British Columbia researchers have discovered a "molecular key" that could help increase the success of blood stem cell transplants, a procedure currently used to treat diseases such as leukemia, Hodgkin's lymphoma and aplastic anemia. http://www.physorg.com/news159630432.html Medicine & Health Wed, 22 Apr 2009 14:47:31 EST news159630432 (PhysOrg.com) -- A research team led by Nancy Speck, PhD, Professor of Cell and Developmental Biology at the University of Pennsylvania School of Medicine, has identified the location and developmental timeline in which a majority of bone marrow stem cells form in the mouse embryo. The findings, appearing online this week in the journal Nature, highlight critical steps in the origin of hematopoietic (or blood) stem cells (HSCs), says senior author Speck, who is also an Investigator with the Abramson Family Cancer Research Institute at Penn. http://www.physorg.com/news150731605.html Biology Fri, 09 Jan 2009 13:53:25 EST news150731605 Like it or not, your living room probably says a lot about you. Given a few uninterrupted moments to poke around, a stranger could probably get a pretty good idea of your likes and dislikes, and maybe even your future plans. Scientists at the Stanford University School of Medicine employing a similar "peeping Tom" tactic to learn more about how stem cells develop have taken a significant step forward by devising a way to recreate the cells' lair - a microenvironment called a niche - in an adult animal. http://www.physorg.com/news148138314.html Biology Wed, 10 Dec 2008 13:31:54 EST news148138314 Taking blood stem cells collected from an umbilical cord into the lab and expanding their number before transplanting them to replace a patient's blood supply is as safe as a standard cord blood transplant, researchers reported today at the 50th Annual Meeting of the American Society of Hematology. http://www.physorg.com/news147975732.html Medicine & Health Mon, 08 Dec 2008 16:22:12 EST news147975732 Stem cell researchers at UCLA have proven definitively that blood stem cells are made during mid-gestational embryonic development by endothelial cells, the cells that line the inside of blood vessels. http://www.physorg.com/news147532604.html Medicine & Health Wed, 03 Dec 2008 13:16:44 EST news147532604 A family of cancer-fighting molecules helps blood stem cells in mice decide when and how to divide, say researchers at the Stanford University School of Medicine. Blocking the molecules' function spurs the normally resting cells to begin proliferating strangely - making too much of one kind of cell and not enough of another. Many types of human blood cancers involve a similar disruption in the expression of that same family of molecules. http://www.physorg.com/news142686276.html Medicine & Health Wed, 08 Oct 2008 12:04:36 EST news142686276 Researchers have shown that immune-defense cells influenced by embryonic stem cell-derived cells can help prevent the rejection of hearts transplanted into mice, all without the use of immunosuppressive drugs. http://www.physorg.com/news140701728.html Medicine & Health Mon, 15 Sep 2008 12:48:48 EST news140701728 Johns Hopkins researchers have discovered the earliest form of human blood stem cells and deciphered the mechanism by which these embryonic stem cells replicate and grow. They also found a surprising biological marker that pinpoints these stem cells, which serve as the progenitors for red blood cells and lymphocytes. http://www.physorg.com/news139249009.html Medicine & Health Fri, 29 Aug 2008 17:16:49 EST news139249009 Japanese researchers may be one step closer to improving treatments for bleeding disorders. A group of researchers from the University of Tokyo has devised a way to maximize the numbers and function of clot-forming blood cells from mice. Their work will be published online in the Journal of Experimental Medicine on July 28. http://www.physorg.com/news136467858.html Medicine & Health Mon, 28 Jul 2008 12:44:18 EST news136467858
