Mathematical innovation turns blood draw into information gold mine in Stanford study (3/10/2010)

Mathematical innovation turns blood draw into information gold mine in Stanford studyScientists at the Stanford University School of Medicine have devised a software algorithm that could enable a common laboratory device to virtually separate a whole-blood sample into its different cell types and detect medically important gene-activity changes specific to any one of those cell types. ...> Full Article


Scientists discover molecular pathway for organ tissue regeneration and repair (2/17/2010)

Scientists have discovered a molecular pathway that works through the immune system to regenerate damaged kidney tissues and may lead to new therapies for repairing injury in other organs. The study in this week's Proceedings of the National Academy of Sciences may have significant medical ramifications as currently there are no effective treatments for acute kidney injury -- a growing problem in hospitals and clinics. ...> Full Article


Study uses sophisticated genetic engineering to improve insulin-producing beta cells (10/9/2009)

A study to be published today in the leading international journal Cell Metabolism describes how a research group led by Dr. Robert Screaton, who holds the Canada Research Chair in Apoptotic Signaling at the University of Ottawa, used sophisticated genetic engineering to remove or "knock out" the Lkb1 gene from beta cells of laboratory mice. The result was an increase in both the size and number of beta cells, as well as greater amounts of insulin stored and released by the cells. ...> Full Article


Stem cell success points to way to regenerate parathyroid glands (10/2/2009)

An early laboratory success is taking University of Michigan researchers a step closer to parathyroid gland transplants that could one day prevent a currently untreatable form of bone loss associated with thyroid surgery. ...> Full Article



Engineering team to design and study liver mimics (9/15/2009)

Engineering team to design and study liver mimicsVirginia Tech College of Engineering researchers will use more than $1 million in grant funding to study engineered tissues that mimic the liver, one of the human body's most complex organs. The primary research goal of these projects is to assemble 3D cellular structures that mimic the liver using the major cell types found in the liver. Liver mimics could eventually form the basis for extracorporeal liver-assist devices. ...> Full Article

Molecular events involved in liver regeneration (12/24/2008)

A research group from Germany investigated if there is a relation between the extent of liver resections and activation of certain molecular processes playing a role in liver regeneration. They found a delayed activation of NF-kappa B and reduced expression of cytokines relevant for beginning and continuation of liver regeneration after liver resection of major extent. ...> Full Article

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

Enzyme Mutation Disrupts Organ Growth (11/29/2007)

The cellular mechanism that turns DNA into all of the thousands of proteins that make up a human body is itself both intricate and interesting. A key player in the process--called transcription--is the enzyme RNA polymerase III. A new study reports that a mutation of this enzyme prevents cell division, but surprisingly, only affects the development of specific organs. It may also have a therapeutic application against cancer. ...> Full Article


Breakthrough in Organ Rejection Diagnosis Examines Gene Behavior (11/25/2007)

New Research describes a revolutionary technique for more clearly identifying the possibility of organ rejection in kidney transplants. The technique, which uses a microarray or "Gene Chip," a process of examining DNA sequences, defines how major causes of organ disease leading to rejection share similar disturbances in gene behavior. The study is the first to show how gene sets, as opposed to single genes, can be used for diagnosis of rejection in individual patients, and offers new insight into the mechanisms of these gene changes. ...> Full Article
