FURTHER STEPS TOWARDS A VACCINE AGAINST HIV
For white blood cells in the human body to be infected by the HIV virus, proteins in the virus must be allowed to interact with a number of different components on the surface of the white blood cell. Ideally anti-HIV preventive therapy or vaccines would prevent several of these interactions taking... view more (1999-03-11)

Scientists find stem cell switch
Scientists have discovered how plant stem cells in roots detect soil structure and whether it is favourable for growth.   view more (2007-07-27)

Cancer stem cells similar to normal stem cells can thwart anti-cancer agents
Current cancer therapies often succeed at initially eliminating the bulk of the disease, including all rapidly proliferating cells, but are eventually thwarted because they cannot eliminate a small reservoir of multiple-drug-resistant tumor cells, called cancer stem cells, which ultimately become... view more (2007-06-18)

New cell culturing method pumps up the volume
In a breakthrough that will likely accelerate research aimed at cures for hearing loss, tinnitus, and balance problems, scientists have perfected a laboratory culturing technique that provides a reliable new source of cells critical to understanding certain inner-ear disorders.   view more (2007-09-25)

Stem cells as cancer therapy
It is widely hoped that neural stem cells will eventually be useful for replacing nerves damaged by degenerative diseases like Alzheimer disease and multiple sclerosis. But there may also be another use for such stem cells-delivering anti-cancer drugs to cancer cells.   view more (2006-12-26)

'Killer' B cells provide new link in the evolution of immunity
Researchers from the University of Pennsylvania School of Veterinary Medicine have discovered a unique evolutionary link between the most primitive innate form of immune defense, which has survived in fish, to the more advanced, adaptive immune response present in humans and other mammals.   view more (2006-10-04)

Dictyostelium cells shown to lay 'breadcrumb trail' as first step in multicellular formation
When starved of their food source and then presented with a chemoattractant signal like cAMP, individual Dictyostelium cells acquire a polarized morphology and aggregate to form a migrating stream.   view more (2008-12-01)

CHECKING HOW CELLS GROW: New research dismisses a widely held assumption about cell growth
Research published today in Journal of Biology challenges an assumption about cell growth that underpins modern cellular biology. Ian Conlon and Martin Raff, of University College London, show that mammalian cells do not regulate their size in the way scientists have assumed they do since the... view more (2003-04-23)

New brain cells listen before they talk
Newly created neurons in adults rely on signals from distant brain regions to regulate their maturation and survival before they can communicate with existing neighboring cells-a finding that has important implications for the use of adult neural stem cells to replace brain cells lost by trauma or... view more (2007-10-31)

Light powered platinum more targeted & 80 times more powerful than similar cancer treatments
Researchers from the Universities of Warwick, Edinburgh, Dundee and the Czech Republic's Institute of Biophysics have discovered a new light-activated platinum-based compound that is up to 80 times more powerful than other platinum-based anti-cancer drugs and which can use "light... view more (2007-12-26)

Researchers aim to cut future need for liver transplants
University of Edinburgh scientists have identified primitive liver cells —possibly dormant from the earliest developmental stage of a human being — which have the potential to mature into different cells types and help repair a failing liver.   view more (2006-07-07)

UCLA researchers develop T-cells from human embryonic stem cells
Researchers from the UCLA AIDS Institute and the Institute for Stem Cell Biology and Medicine have demonstrated for the first time that human embryonic stem cells can be genetically manipulated and coaxed to develop into mature T-cells, raising hopes for a gene therapy to combat AIDS.   view more (2006-07-05)

When smell cells fail they call in stem cell reserves
Hopkins researchers have identified a backup supply of stem cells that can repair the most severe damage to the nerves responsible for our sense of smell.   view more (2007-04-30)

How insulin-producing cells develop -- new finding could help fight against diabetes
A key aspect of how embryos create the cells which secrete insulin is revealed in a new study published tomorrow (18 May) in the Journal of Biological Chemistry.   view more (2007-05-18)

Enzyme promotes fat formation
The enzyme TPPII may contribute to obesity by stimulating the formation of fat cells, suggests a study in EMBO reports this week. The enzyme, TPPII, has previously been linked to making people feel hungry, but Jonathan Graff and colleagues now show that it may be even more deeply involved in... view more (2007-10-12)

Healthy blood vessels may prevent fat growth
The cells lining blood vessels are known to be important for maintaining health, but researchers at the Indiana University School of Medicine believe these cells may perform an unsuspected task - controlling the development of fat cells.   view more (2008-09-22)

Inflammation kills new brain cells
A research team at Lund University in Sweden attracted international attention a year ago by showing that new nerve cells can be generated in the brain after a stroke. However, most of these new nerve cells die rather soon. The same research team has now been able to show that an inflammation can... view more (2003-11-10)

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... view more (2008-08-29)

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)

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)

Evidence of flooding at Mangala Valles
These images of fluvial surface features at Mangala Valles on Mars were obtained by the High Resolution Stereo Camera (HRSC) on board the ESA Mars Express spacecraft. The HRSC has imaged structures several times which are related to fluvial events in the past on Mars. The region seen here is... view more (2004-06-09)

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),... view more (2003-01-29)

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... view more (2008-05-27)
