U of MN researchers use human embryonic stem cells to kill cancer cells
For the first time, stem cell researchers at the University of Minnesota have coaxed human embryonic stem cells to create cancer-killing cells in the laboratory, paving the way for future treatments for various types of cancers (or tumors).   view more (2005-10-12)

Tiny fuel cell might replace batteries in laptop computers, portable electronics
If you're frustrated by frequently losing battery power in your laptop computer, digital camera or portable music player, then take heart: A better source of "juice" is in the works.   view more (2006-09-13)

White blood cell count, inflammation linked to cancer deaths
In a study of more than 3,000 older Australians, those with a higher white blood cell count, a sign of inflammation, were more likely to die of cancer.   view more (2006-01-24)

Adult sickle cell drug proves effective in young children
A drug used for the treatment of sickle cell anemia in adults has now been shown to cause significant improvements in very young children with the disorder.   view more (2005-09-20)

Stem cell study seeks to prevent heart failure
University of Rochester Medical Center researchers today announced the launch of a study that will examine whether transplanted stem cells can be safely used to treat damaged heart muscle in patients just after their first heart attack.   view more (2006-01-25)

MicroRNA tweaks protein that controls early heart development
Researchers at UT Southwestern Medical Center have discovered how a small molecule of RNA called microRNA - a chemical cousin of DNA - helps fine tune the production of a key protein involved in the early development of heart muscle.   view more (2005-06-13)

No cell walls, no new cancer cells
Cancer cells, like houses, need building materials for their walls. And as with a house, the cell wall needs to be built at just the right moment to protect and allow the construction of internal components.   view more (2006-08-02)

Synthetic molecule causes cancer cells to self-destruct
Scientists have found a way to trick cancer cells into committing suicide. The novel technique potentially offers an effective method of providing personalized anti-cancer therapy.   view more (2006-08-28)

Penn study finds hyperbaric oxygen treatments mobilize stem cells
According to a study to be published in the American Journal of Physiology-Heart and Circulation Physiology, a typical course of hyperbaric oxygen treatments increases by eight-fold the number of stem cells circulating in a patient's body.   view more (2005-12-29)

World-first stem cell research could aid male infertility
Scientists have shown for the first time that sperm grown from embryonic stem cells can be used to produce offspring.   view more (2006-07-11)

Eggs from embryonic stem cells could benefit sterile women
Monash researchers have developed a process that causes embryonic stem (ES) cells to develop into ovarian structures containing eggs.    view more (2005-06-20)

Cell-regulating gene may predict survival outcomes for breast cancer patients
A study led by researchers at Mount Sinai School of Medicine has shown that a cell-regulating gene overexpressed in about 30 to 50 percent of all breast cancers is associated with a better chance of survival and increased sensitivity to a cancer-fighting drug.   view more (2006-09-06)

Engineered stem cells show promise for sneaking drugs into the brain
One of the great challenges for treating Parkinson's diseases and other neurodegenerative disorders is getting medicine to the right place in the brain.   view more (2005-12-15)

Chemotherapy can be more toxic to brain cells than to cancer cells and may cause brain damage
Drugs used to treat cancer may damage normal, healthy brain cells more than the cancer cells they are meant to target.   view more (2006-11-30)

Rapid restoration of immunity in immune-suppressed cancer patients using T-cell vaccines
Patients with multiple myeloma suffer from a malignant proliferation of plasma cells in their bone marrow.   view more (2005-10-21)

Subtypes of ependymomas arise from rare stem cells in the nervous system
Brain tumors called ependymomas that occur in different parts of the central nervous system appear to arise from subpopulations of stem cells called radial glia cells (RGCs).   view more (2005-10-18)

Bone marrow stem cells may heal hearts even years after heart attacks
Left ventricular function and exercise capacity increased, while the area of heart muscle damage shrank, in 18 patients given infusions of their own bone marrow stem cells up to eight years after a heart attack   view more (2005-10-27)

Human beta-cell line offers hope for type 1 diabetes breakthrough
Transplantation of insulin-producing pancreatic beta-cells shows great promise as a treatment for type 1 diabetes, but development of this therapy has been hampered by a severe shortage of donor beta-cells, which are obtained from decreased human donors.   view more (2005-09-27)

Progress made in HIV vaccine development
Researchers have successfully tested two candidate vaccines that may eventually be used together to confer immunity against HIV infection. Their findings are published in the December 15 issue of The Journal of Infectious Diseases, now available online.   view more (2006-11-13)

Human embryonic stem cells have the potential to develop into eggs and sperm in the laboratory
Scientists in the UK have proved that human embryonic stem cells can develop in the laboratory into the early forms of cells that eventually become eggs or sperm.   view more (2005-06-20)

Novel stem cell technology leads to better spinal cord repair
Researchers believe they have identified a new way, using an advance in stem-cell technology, to promote recovery after spinal cord injury of rats, according to a study published in today's Journal of Biology.   view more (2006-04-28)

Stem cell transplants improve recovery in animal models for stroke, cerebral palsy
A single dose of adult donor stem cells given to animals that have neurological damage similar to that experienced by adults with a stroke or newborns with cerebral palsy can significantly enhance recovery from these types of injuries, researchers say.   view more (2006-04-10)

Discovery in 'Bubble Boy' disease gene therapy
Scientists at St. Jude Children's Research Hospital have developed a mouse model of a severe disease of the immune system that helps explain why gene therapy used to treat children with this disease at an institution in Europe caused some of them to develop leukemia.   view more (2006-08-02)

Mad-cow culprit maintains stem cells
What do mad cow disease and stem cell research have in common? Whitehead Institute scientists have found that the same protein that causes neurodegenerative conditions such as bovine spongiform encephalopathy (mad cow disease) is also important for helping certain adult stem cells maintain... view more (2006-01-31)

Elevated testosterone kills nerve cells
A Yale School of Medicine study shows for the first time that a high level of testosterone, such as that caused by the use of steroids to increase muscle mass or for replacement therapy, can lead to a catastrophic loss of brain cells.   view more (2006-09-27)
