Embryonic stem cells might help reduce transplantation rejection
Researchers have shown that immune-defense cells influenced by embryonic stem cell-derived cells can help prevent the rejection of hearts transplanted into mice, all without the use of immunosuppressive drugs.   view more (2008-09-16)

Purifying parasites with light
Researchers have developed a clever method to purify parasitic organisms from their host cells, which will allow for more detailed proteomic studies and a deeper insight into the biology of organisms that cause millions of cases of disease each year.   view more (2008-09-15)

Stem cell regeneration repairs congenital heart defect
Mayo Clinic investigators have demonstrated that stem cells can be used to regenerate heart tissue to treat dilated cardiomyopathy, a congenital defect.   view more (2008-09-12)

OU Cancer Institute Scientists Identify New Cancer Stem Cell Marker; Developing Drug to Stop Cancer Recurrence
After years of working toward this goal, scientists at the OU Cancer Institute have found a way to isolate cancer stem cells in tumors so they can target the cells and kill them, keeping cancer from returning.    view more (2008-09-12)

DNA 'tattoos' link adult, daughter stem cells in planarians
Unlike some parents, adult stem cells don't seem to mind when their daughters get a tattoo. In fact, they're willing to pass them along.   view more (2008-09-11)

Human embryonic stem cell secretions minimized tissue injury after heart attack
A novel way to improve survival and recovery rate after a heart attack was reported in the journal Stem Cell Research by scientists at Singapore's Institute of Medical Biology (IMB) and Bioprocessing Technology Institute (BTI) and The Netherlands' University Medical Center Utrecht.   view more (2008-09-10)

New paper sheds light on bacterial cell wall recycling
A new paper by a team of researchers led by Shahriar Mobashery, Navari Family Professor of Life Sciences at the University of Notre Dame, provides important new insights into the process by which bacteria recycle their cell wall.   view more (2008-09-09)

What is a gene?
Even scientists define 'a gene' in different ways, so it comes as little surprise that the media also have various ways of framing the concept of a gene.   view more (2008-09-08)

Updated guidelines for stem cell research released
The National Academies today released amended guidelines for research involving human embryonic stem cells, revising those that were issued in 2005 and updated in 2007.   view more (2008-09-08)

NIST and partners identify tiny gold clusters as top-notch catalysts
For most of us, gold is only valuable if we possess it in large-sized pieces. However, the "bigger is better" rule isn't the case for those interested in exploiting gold's exceptional ability to catalyze a wide variety of chemical reactions, including the oxidation of poisonous carbon... view more (2008-09-08)

New studies on the Mediterranean diet confirm its effectiveness for chronic disease prevention
Scientists of the Instituto de Nutrición y Tecnología de los Alimentos (Institute of Nutrition and Food Technology) of the University of Granada (UGR, Spain) have been doing research into the positive effects of Mediterranean diet's ingredients on health.   view more (2008-09-08)

TAU Researchers Create New Stem Cell Screening Tool
Stem cell research is the next great leap in medicine. In the future, new tissue grown in a laboratory could replace a failing heart, or new cells take the place of damaged cells in the brain.   view more (2008-09-05)

Scientists uncover Ebola cell-invasion strategy
University of Texas Medical Branch at Galveston researchers have discovered a key biochemical link in the process by which the Ebola Zaire virus infects cells - a critical step to finding a way to treat the deadly disease produced by the virus.   view more (2008-09-04)

NC State Is First University in Nation to Offer Canine Bone Marrow Transplants
Dogs suffering from lymphoma will be able to receive the same type of medical treatment as their human counterparts, as North Carolina State University becomes the first university in the nation to offer canine bone marrow transplants in a clinical setting.   view more (2008-09-04)

Hearing restoration may be possible with cochlear repair after transplant of human cord blood cells
According to an Italian research team publishing their findings in the current issue of Cell Transplantation (17:6), hearing loss due to cochlear damage may be repaired by transplantation of human umbilical cord hematopoietic stem cells (HSC) since they show that a small number migrated to the... view more (2008-09-04)

Cardiac cell transplant studies show promise in cardiac tissue repair
Two studies published in the current issue of CELL TRANSPLANTATION (17:6) examine the efficacy of transplanting bone marrow cells (BMCs) for the repair of heart tissue.    view more (2008-09-04)

DNA editing tool flips its target
Imagine having to copy an entire book by hand without missing a comma. Our cells face a similar task every time they divide. They must duplicate both their DNA and a subtle pattern of punctuation-like modifications on the DNA known as methylation.   view more (2008-09-04)

Stem cell research puts interstate rivalry on hold
Victoria and New South Wales have put aside their competitive interstate rivalry to collaborate on a stem cell research project, as announced by Innovation Minister Gavin Jennings and NSW Minister for Science and Medical Research, Verity Firth, today.   view more (2008-09-04)

Battling Diabetes with Beta Cells
Affecting eight percent of America's population, diabetes can lead to blindness, kidney failure, strokes and heart disease. Thanks to Tel Aviv University researchers, a new cure -- based on advances in cell therapy -- may be within reach.   view more (2008-09-03)

VCU Massey Cancer Center Spearheads Novel Clinical Study for Lymphoma Patients
The Virginia Commonwealth University Massey Cancer Center recently opened a National Cancer Institute (NCI)-sponsored, phase II clinical study for certain sub-types of non-Hodgkin's lymphoma.   view more (2008-09-03)

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)

NIAID describes challenges, prospects for an HIV vaccine
Events of the past year in HIV vaccine research have led some to question whether an effective HIV vaccine will ever be developed. In the August 28 edition of the New England Journal of Medicine, officials from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National... view more (2008-08-28)

Variation of normal protein could be key to resistance to common cancer drug
Researchers at the Moores Cancer Center at the University of California, San Diego (UC SD) in La Jolla have found evidence explaining why a common chemotherapy drug, cisplatin, may not always work for every cancer patient. They have shown that when a variant version of a key protein that normally... view more (2008-08-28)

Cell removal technique could lead to cheaper drugs
Researchers at the University of Edinburgh have pioneered a simple way to remove dead cells from cell cultures used to make protein-based drugs, which are increasingly prescribed to treat a range of illnesses.   view more (2008-08-27)

Angiotensin inhibitors and receptor blockers linked to lower risk of nonmelanoma skin cancer
The use of angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) was associated with a reduced risk of basal cell or squamous cell skin cancers in U.S. veterans, researchers report in the August 26 online issue of the Journal of the National Cancer Institute.   view more (2008-08-27)
