Cell culture is the process of isolating cells from an organism and growing them in a scientifically controlled environment

Cruelty-free ELISA for human insulin

In the January issue of Clinical Biochemistry, scientists and physicians with the Physicians Committee for Responsible Medicine (PCRM) outline the method used to develop a cruelty-free ELISA for human insulin that uses monoclonal antibodies produced by cells cultured in an animal-serum-free medium.

FDA issues guidance for development of cell-based viral vaccines

The U.S. Food and Drug Administration (FDA) has issued new guidance to aid manufacturers in developing safe and effective cell-based viral vaccines.

p120 catenin protein can stop metastasis or promote it

A protein known to be a key component of the glue that holds cells together also is involved in breaking them apart and promoting their movement when tumors begin to spread to other parts of the body, researchers at Mayo Clinic have found.

New screening method shows how nanoparticles interact with human cells

Scientists at the Brookhaven National Laboratory have developed a screening method to examine how newly made nanoparticles interact with human cells following exposure for various times and doses. Using this new method, the investigators have been able to visualize how human cells interact with some specific types of carbon nanoparticles.

Juice lowers Alzheimer's risk

In a large epidemiological study, researchers found that people who drank three or more servings of fruit and vegetable juices per week had a 76 percent lower risk of developing Alzheimer's disease than those who drank juice less than once per week.

New methods for screening nanoparticles and interaction with human cells

Scientists have developed a screening method to examine how newly made nanoparticles - particles with dimensions on the order of billionths of a meter - interact with human cells following exposure for various times and doses.

Birch bark compound may be potent prostate cancer fighter

A compound found in the bark of the white birch tree - betulonic acid, a derivative of betulinol - may finally have been rendered a water-soluble, bio-available drug, and is already showing the potential to be a possible agent against prostate cancer - in cell culture and in an animal model.

Human hair follicles found to be a new source of adult stem cells

Researchers at the University of Pennsylvania School of Medicine have isolated a new source of adult stem cells that appear to have the potential to differentiate into several cell types.

Statins stop the replication of the hepatitis C virus

A new study shows that statins, which are typically used as anti-cholesterol medications, can inhibit the replication of the hepatitis C virus (HCV).

AUA podium session on stone disease

2-phase randomized crossover study on a constant diet with calcium carbonate supplementation at 250 mg 4 times daily.

Hydrophobic statins not associated with increased breast cancer risk

A report published in the Journal of the National Cancer Institute found that women who took statins--the widely used cholesterol lowering drugs--do not face an increased breast cancer risk as had been suggested by some previous studies.

Scientists use "small interfering RNAs" to block the spread of human colorectal cancer cells

Using one of the newest and most powerful tools of biomedical science, University of Texas Medical Branch at Galveston (UTMB) researchers have scored a dramatic success in the battle against colorectal cancer.

Signaling pathways in immune cells may lead to novel HIV treatment

New research on signaling pathways in immune cells bolsters evidence of connections between the central nervous system and the immune system.

Differential effects of HOXB4 on nonhuman primate short and long-term repopulating cells

Transplantation of hematopoietic stem cells (HSCs, the cells that can give rise to all blood and most immune cell types) can save patients whose own hematopoietic system is defective or has been destroyed (often through radiation or chemotherapy of cancer).

Lipoxin A4 regulates bronchial epithelial cell responses to acid injury

Doctors are gaining new leverage in the fight against lung injury caused by acid reflux. The paper by Bonnans et al., "Lipoxin A4 regulates bronchial epithelial cell responses to acid injury," appears in the April issue of The American Journal of Pathology and is accompanied by a commentary.

Three-dimensional breast cell cultures reveal clues to breast cancer hidden inside stem cells

Stem cells and how to boost them is hot on the research agenda. But stopping them could be critical too, as evidence implicating stem cells in cancer is mounting.

Blood cancers may be caused by inactivation of a "tumor suppressor" gene

The discovery of a gene, called PRDM1, as a tumor suppressor sheds new light on the cause - and possible treatment - of diffuse large B-cell lymphomas (DLBCLs), a cancer of the blood's B-lymphocytes. DLBCLs comprise about 30 percent of non-Hodgkin's lymphomas.

Kidney treatments may be improved with new understanding of cell death mechanism

Finding how two proteins conspire to get kidney cells to self-destruct when oxygen supplies are low may one day improve dismal mortality rates for ischemic renal failure, researchers say.

New finding provides researchers with renewable source for macrophages and neutrophils

A new approach to generating large quantities of two types of white blood cells that are critical for destroying invading bacteria, viruses and other pathogens in humans has been developed by researchers at the University of California, San Diego (UCSD) School of Medicine.
