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)
Human ES cells progress slowly in myelin's direction
Scientists from the University of Wisconsin, USA, report in the journal Development the successful generation from human embryonic stem cells of a type of cell that can make myelin, a finding that opens up new possibilities for both basic and clinical research. view more (2009-04-09)
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 1970s. Conlon and Raff conducted a series of... 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 neurodegeneration, Yale School of Medicine... view more...

Malaria parasite impairs key immune system cells
Plasmodium, the parasite responsible for malaria, impairs the ability of key cells of the immune system to trigger an efficient immune response. view more (2006-04-12)
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 activation" to kill cancer cells in much more targeted way... view more...

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)
Unlocking the body's defenses against cancer
Scientists have discovered a way of allowing healthy cells to take charge of cancerous cells and stop them developing into tumours in what could provide a new approach to treating early-stage cancers. view more (2009-08-26)
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)
Stanford scientists turn adult skin cells into muscle and vice versa
In a study featured on the cover of the May issue of The FASEB Journal, researchers describe how they are able to reprogram human adult skin cells into other cell types in order to decipher the elusive mechanisms underlying reprogramming. view more (2009-04-30)
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)
Parasite lipids against asthma or diabetes
Dutch research has demonstrated that lipids from the parasite schistosoma can inhibit human immune responses. This property makes the lipids interesting for a possible new treatment of diseases such as asthma and diabetes where the immune system responds inappropriately. During her doctoral research, Desiree van der Kleij discovered that lipids... view more... (2003-11-11)
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 causing obesity. view more (2007-10-12)
Hebrew University researchers neutralize tumor growth in embryonic stem cell therapy
Researchers at the Hebrew University of Jerusalem have discovered a method to potentially eliminate the tumor-risk factor in utilizing human embryonic stem cells. view more (2009-05-07)
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)
Is hepatic differentiation of embryonic stem cells induced by valproic acid and cytokines?
Embryonic stem (ES) cells, known for their capacity to proliferate indefinitely and differentiate into almost all types of cells including hepatocytes, have raised the hope of cellular replacement therapy for liver failure. view more (2009-11-18)
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 lie behind the death of these new nerve cells,... view more...
