Human stem cell transplants mature into neurons and make contacts in rat spinal cord
Human nerve stem cells transplanted into rats' damaged spinal cords have survived, grown and in some cases connected with the rats' own spinal cord cells in a Johns Hopkins laboratory, overturning the long-held notion that spinal cords won't allow nerve repair. view more (2007-02-14)
Blood vessel cells are instructed to form tube-like structures
How do blood vessel cells understand that they should organise themselves in tubes and not in layers? A research group from Uppsala University shows for the first time that a special type of "instructor" molecule is needed to accomplish this. These findings, published in the scientific journal Blood, might be an important step towards... view more... (2008-08-29)
Scientists identify new role for lung epithelial cells in sensing allergens in the air
Researchers at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, and at Ghent University in Ghent, Belgium, have identified a new role for certain lung cells in the immune response to airborne allergens. view more (2009-03-31)
New U of T strategy will boost cord blood stem cells
A team of bioengineers led by the University of Toronto has discovered a way to increase the yield of stem cells from umbilical cord blood, to an extent which could broaden therapeutic use of these cells. view more (2005-10-19)
New findings on the formation of body pigment
The skin's pigment cells can be formed from completely different cells than has hitherto been thought, a new study from the Swedish medical university Karolinska Institutet shows. The results, which are published in the journal Cell, also mean the discovery of a new kind of stem cell. view more (2009-10-19)
Engineered pig stem cells bridge the mouse-human gap
The discovery that adult skin cells can be 'reprogrammed' to behave like stem cells has been a major scientific boon, providing a way to tap the potential of embryonic stem cells without the associated ethical quandaries. view more (2009-06-04)
Iron induces death in tumor cells
Rapid growth of cancer cells and their frequent divisions have their price: Cancer cells need considerably more energy than healthy cells. view more (2009-03-11)
Studying component parts of living cells with carbon nanotube cellular probes
Carbon nanotubes (CNTs) have shown great potential for use as cellular probes. As "nanopipes" they can be used to transport liquids to or from cells and inject solutions or drugs directly into individual cells and individual organelles within the cells. view more (2007-10-05)
Cornell researchers identify a weak link in cancer cell armor
The seeming invincibility of cancerous tumors may be crumbling, thanks to a promising new gene therapy that eliminates the ability of certain cells to repair themselves. view more (2009-11-13)
UBC research finds molecular
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. view more (2009-04-23)
US funding for Lund research for project on adult stem cells
Adult stem cells are to be treated so that they develop characteristics of nerve cells and can produce dopamine, according to Associate Professor Jia-Yi Li at the Wallenberg Neuro Center at Lund University, who has received a grant of some SEK 2 million from the National Institutes of Health (NIH), the American counterpart of the Swedish Research... view more...

Tumor cells evade death through autophagy
Autophagy is a cellular process that enables cells to turnover their contents, something that they do frequently. Autophagy is initiated in tumor cells by chemotherapy and radiation, but it is not known if this contributes to tumor cell death or helps tumor cells survive the anti-cancer therapy. view more (2007-01-19)
Dual functions of gene revealed, for better and for worse
Researchers at WEHI have pinpointed the function of a potent cancer gene. The gene, known as "ERG", has long been associated with a range of human malignancies, including leukemia and sarcoma. American scientists showed in 2005 that ERG is mutated in more than half of all prostate cancers. view more (2008-05-27)
Geisinger study: Inflammatory disease causes blindness
People suffering from a type of connective tissue disease characterized by inflammation of arteries in the head are three times more likely to experience blindness, new Geisinger research shows. view more (2008-06-17)
Researchers identify a cell type that limits stroke damage
A research team including Serge Rivest of University Laval's Faculty of Medicine has demonstrated the existence of a type of cells that limits brain damage after a stroke. The study was recently published in the online version of Nature Medicine. view more (2009-01-28)
Tracking the spread of cancer cells - Photon02
Not much is known about how clustered cancer cells move, but it is important to understand how individual cancer cells break off from a cluster and spread throughout the human body. A research collaboration between the University of Wales College of Medicine and Kingston University * has lead to the development of a computational imaging technique... view more... (2002-08-28)
Cellular self-eating promotes pancreatitis
To survive tough times, cells sometimes resort to a form of self-cannibalism called autophagy. But as Hashimoto et al. reveal, autophagy can have a down side, destroying the pancreas by prematurely activating a digestive enzyme. view more (2008-06-30)
Isolation of a new gene family essential for early development
Researchers at BRIC, University of Copenhagen, have identified a new gene family (UTX-JMJD3) essential for embryonic development. The family controls the expression of genes crucial for stem cell maintenance and differentiation, and the results may contribute sig-nificantly to the understanding of the development of cancer. view more (2007-08-23)
New evidence explains poor infant immune response to certain vaccines, says MU researcher
For years, researchers and physicians have known that infants' immune systems do not respond well to certain vaccines, thus the need for additional boosters as children develop. view more (2009-04-02)
USC researchers discover breast cancer stem cells in bone marrow
Almost all tumor cells found in the bone marrow of early stage breast cancer patients appear to be breast cancer stem cells, suggesting the risk of disease spread for all breast cancer patients may be greater than previously thought. view more (2006-10-09)
