From Stem Cells To Organs: The Bioengineering Challenge (2/17/2008)

For more than a decade, Peter Zandstra has been working at the University of Toronto to rev up the production of stem cells and their descendants. The raw materials are adult blood stem cells and embryonic stem cells. The end products are blood and heart cells -- lots of them. Enough mouse heart cells that they form beating tissue. ...> Full Article

Gene Therapy Protocol Activates Immune System in Patients with Leukemia (2/13/2008)

A research team at the Rebecca and John Moores UCSD Cancer Center at University of California, San Diego (UCSD) reports that patients with chronic lymphocytic leukemia (CLL) who were treated with a gene therapy protocol began making antibodies that reacted against their own leukemia cells. The study will be published on line the week of February 11-15 in the online edition of the Proceedings of the National Academy of Science. ...> Full Article

Discovery Of Good - And Bad - Liver Stem Cells Raises Possibility Of New Treatment (2/12/2008)

Many scientists believe up to 40 percent of liver cancer is caused by stem cells gone wild -- master cells in the organ that have lost all growth control. But, despite years spent looking, no one has ever found these liver "cancer stem cells" -- or even normal stem cells in the organ. Until now. ...> Full Article

Bone Marrow Stem Cell Release Regulated By Brain's Biological Clock (2/8/2008)

Mount Sinai researchers have discovered that the release of blood stem cells from bone marrow is regulated by the brain through the cyclical human biological clock, via adrenergic signals transmitted by the sympathetic nervous system. These new findings point out that the harvest of stem cells for transplantation may be improved by timing it at the peak of their release. ...> Full Article

Medicine From Milk: Gene Therapy Transforms Goats Into Pharmaceutical Factories (2/1/2008)

University of Pennsylvania researchers have used gene therapy to reduce the time it takes to breed large animals capable of producing therapeutic proteins in their milk, such as insulin or those that fight cancer. This represents a significant milestone in drug development, as current methods involve cloning, which takes more time and generally costs more. ...> Full Article

New research into scar-free healing (1/28/2008)

New research from the University of Bristol shows that by suppressing one of the genes that normally switches on in wound cells, wounds can heal faster and reduce scarring. This has major implications not just for wound victims but also for people who suffer organ tissue damage through illness or abdominal surgery. ...> Full Article

Key Bone Building Pathway Identified in Mice (1/28/2008)

Researchers at the San Francisco VA Medical Center, University of California, San Francisco, and Gladstone Institute of Cardiovascular Disease have uncovered a biochemical signaling pathway that leads to the formation of abnormally large bones in mice. For humans, the discovery may provide clues to both childhood bone formation and osteoporosis -- the loss of bone in old age -- as well as a path to improved osteoporosis treatments. The research is detailed in a paper in the online Early Edition of the Proceedings of the National Academy of Sciences. ...> Full Article

Protein that controls hair growth also keeps stem cells slumbering (1/27/2008)

Like fine china and crystal, which tend to be used sparingly, stem cells divide infrequently. It was thought they did so to protect themselves from unnecessary wear and tear. But now new research from Rockefeller University has unveiled the protein that puts the brakes on stem cell division and shows that stem cells may not need such guarded protection to maintain their potency. ...> Full Article
