Developing cancer treatments directed at critical developmental pathway
Researchers from the University of Pennsylvania School of Medicine and colleagues discovered that the Notch signaling pathway, which determines the development of many cell types, and is also implicated in some cancers, is not universally essential for the maintenance of stem cells.   view more (2008-04-11)

Penn researchers discover 'modus operandi' of heart muscle protein
Researchers at the University of Pennsylvania School of Medicine have discovered that a protein called leiomodin (Lmod) promotes the assembly of an important heart muscle protein called actin. What's more, Lmod directs the assembly of actin to form the pumping unit of the heart. The findings appear... view more (2008-04-11)

Embryonic stem cells could help to overcome immune rejection problems
Tissues derived from embryonic stem (ES) cells could help to pacify the immune system and so prevent recipients from rejecting them, the UK National Stem Cell Network Science Meeting will hear today (11 April).   view more (2008-04-11)

Secrets of cellular signaling shed light on new cancer stem cell therapies
By revealing the inner workings of a common cell-to-cell signaling system, University of Michigan biologists have uncovered new clues about mysterious and contentious creatures called cancer stem cells.   view more (2008-04-10)

Heart stem cell scientist to honor pioneering woman scientist in keynote speech
Professor Christine Mummery, one of the world's leading heart stem cell experts, will later today (9 April) honour the memory of Dame Anne McLaren in the keynote lecture of the inaugural UK National Stem Cell Network Science Meeting in Edinburgh.   view more (2008-04-10)

New research shows neuroprotective effect of lovastatin
High cholesterol levels are considered to be a risk factor for cardiovascular disease including stroke.   view more (2008-04-10)

Cells on path to becoming mature T-cells more flexible than commonly thought
Contrary to the currently accepted model of T-cell development, researchers at the University of Pennsylvania School of Medicine have found that juvenile cells on their way to becoming mature immune cells can develop into either T cells or other blood-cell types versus only being committed to the... view more (2008-04-10)

The future of solar-powered houses is clear
People could live in glass houses and look at the world through rose-tinted windows while reducing their carbon emissions by 50% thanks to QUT Institute of Sustainable Resources (ISR) research.   view more (2008-04-10)

Scientists uncover the potential to control adult stem cells
Research being presented today (10 April) at the UK National Stem Cell Network Annual Science Meeting in Edinburgh represents a step towards the use of Adult Stem Cells (ASCs) to repair damaged tissue.   view more (2008-04-10)

Stem cells and cancer: cancer pathways that also control the adult stem cell population
Speaking today (10 April) at the UK National Stem Cell Network Annual Science Meeting in Edinburgh, Professor Alan Clarke from Cardiff University describes his work to investigate a mechanism that normally drives adult stem cells to repair the intestine.   view more (2008-04-10)

Identification of dopamine 'mother cells' could lead to future Parkinson's treatments
'Mother cells' which produce the neurons affected by Parkinson's disease have been identified by scientists, according to new research published in the journal Glia.   view more (2008-04-08)

Blood pressure enzyme can have tumor-sensing role
By increasing production of a blood pressure-regulating enzyme in mice, researchers have found they can enhance the mouse immune system's ability to sense tumor growth.   view more (2008-04-08)

Stem cell breakthrough offers diabetes hope
Scientists have discovered a new technique for turning embryonic stem cells into insulin-producing pancreatic tissue in what could prove a significant breakthrough in the quest to find new treatments for diabetes.   view more (2008-04-03)

MU researcher links hormone replacement therapy to breast cancer
Millions of post-menopausal women use hormone replacement therapy (HRT) as a method to reduce symptoms associated with menopause. In a recent University of Missouri study, researchers found that one of the hormones used in HRT, a synthetic progestin, could be a major factor in promoting breast... view more (2008-04-02)

Stem Cells from Hair Follicles May Help
For a rich source of stem cells to be engineered into new blood vessels or skin tissue, clinicians may one day look no further than the hair on their patients' heads, according to new research published earlier this month by University at Buffalo engineers.   view more (2008-03-31)

Scientists learn what's 'up' with a class of retinal cells in mice
Harvard University researchers have discovered a new type of retinal cell that plays an exclusive and unusual role in mice: detecting upward motion. The cells reflect their function in the physical arrangement of their dendrites, branch-like structures on neuronal cells that form a communicative... view more (2008-03-28)

Basis created for directing and filming blood vessels
A new method of filming blood-vessel cells that move in accordance with targeted signals has been developed by researchers at Uppsala University in collaboration with researchers at the University of California. The method can also be used to study how migration of cancer cells and nerves can be... view more (2008-03-27)

Strengthening the tumor-fighting ability of T cells
When faced with cancer, the immune system dispatches cells, called T cells, to kill the tumor. But these killer cells often fail to completely eliminate the tumor because they're deactivated by a distinct population of T cells known as regulatory T cells.   view more (2008-03-25)

Subterfuge, counter-surveillance and assassination: The body's fight with cervical cancer
The virus responsible for most cases of cervical cancer has a serious weakness which may provide hope for new treatments for the disease.   view more (2008-03-24)

Therapeutic cloning treats Parkinson's disease in mice
Research led by investigators at Memorial Sloan-Kettering Cancer Center (MSKCC) has shown that therapeutic cloning, also known as somatic-cell nuclear transfer (SCNT), can be used to treat Parkinson's disease in mice. The study's results are published in the March 23 online edition of the journal... view more (2008-03-24)

Protein protects embryonic stem cells' versatility and self-renewal
A protein known as REST blocks the expression of a microRNA that prevents embryonic stem cells from reproducing themselves and causes them to differentiate into specific cell types, scientists at The University of Texas M. D. Anderson Cancer Center report in the journal Nature.   view more (2008-03-24)

Coming soon: Cell therapies for diabetes, cancer?
Therapies using stem cell transplants are advancing promising treatments for such conditions as Alzheimer's Disease, neurological diseases and spinal cord injury, and heart disease.   view more (2008-03-20)

How is H pylori adhesion to gastric cells associated with MUC1 mucin VNTR size?
The Gram negative bacterium H pylori is involved in the pathogenesis of several gastrointestinal diseases, ultimately leading to gastric carcinoma. Adhesion of the bacteria to the gastric mucosa is an essential step for colonization and infection.   view more (2008-03-19)

Stopping a receptor called 'nogo' boosts the synapses
New findings about a protein called the nogo receptor are offering fresh ways to think about keeping the brain sharp.   view more (2008-03-19)

Scientists successfully awaken sleeping stem cells
Scientists at Schepens Eye Research Institute have discovered what chemical in the eye triggers the dormant capacity of certain non-neuronal cells to transform into progenitor cells, a stem-like cell that can generate new retinal cells.   view more (2008-03-19)
