- New culture method for hepatitis C virus uses primary hepatocytes and patient serum
01-23-2007 · EurekAlert!
Researchers open the way for improved study of hepatitis C virus by devising a novel virus culture system that allows replication of patient-isolated virus in nontransformed hepatocytes, instead of culture-adapted virus strains in transformed cell lines. The related report by Lбzaro et al, "Hepatitis C virus replication in transfected and serum-infected cultured human fetal hepatocytes," appears in the February issue of the American Journal of Pathology.

- Weizmann Institute scientists discover a key player in embryonic muscle development
04-11-2007 · EurekAlert!
In the final stage of muscle fiber development, the cell membranes of attached myoblasts open up and fuse together, forming one large, unified cell. It is known how myoblasts identify other myoblasts and cling together, but the way that the cell membranes fuse into one has remained a mystery. Scientists have now discovered that a protein called WIP plays a key role in muscle cell fusion.

- MicroRNA regulates cancer stem cells
12-13-2007 · EurekAlert!
Researchers have discovered a key molecular switch that regulates cancer stem cells. This switch, which belongs to a class of molecules called microRNAs, can decrease a cancer stem cell's ability to propagate tumors. These findings offer a way for targeting cancer stem cells directly, and as a result open up new avenues for potentially treating cancer as a whole.

- Bone marrow cell transplants help nerve regeneration
12-04-2007 · EurekAlert!
Researchers inserted bone marrow-derived cells (BMCs) into 15mm silicon tubes and subsequently implanted into animal models at sites intended for nerve regeneration. When the BMCs were nourished with bioengineered additives -- such as growth factors and cell adhesion molecules -- the BMCs differentiated into cells with characteristics of Schwann cells -- a variety of neural cell providing insulating myelin around the axons of peripheral nerve cells. The work represents a further step in developing artificial nerves.

- Children with gene show reduced cognitive function
11-05-2007 · EurekAlert!
Children possessing a gene known to increase Alzheimer's disease risk already show signs of reduced cognitive function, an Oregon Health & Science University study has found. Scientists discovered that 7- to 10-year-olds with a member of a family of genes implicated in development, nerve cell regeneration and neuroprotection display reduced spatial learning and memory, associated with later-life cognitive impairments. This suggests brain changes predisposing a person to Alzheimer's might occur much sooner than previously thought.

- Innovative movies show real-time immune-cell activity within tumors
11-20-2006 · EurekAlert!
Using advanced new microscopy techniques in concert with sophisticated transgenic technologies, scientists have for the first time created three-dimensional, time-lapse movies showing immune cells targeting cancer cells in live tumor tissues. Immune cells called T cells can be seen actively migrating though tissues, making direct contact with tumor cells, and killing them. Insights from this new view of the body's on-board defenses against cancer may open the way for improved immunotherapies to treat the disease.

- Milestone in the regeneration of brain cells
08-20-2007 · EurekAlert!
Neuherberg, 20 Aug. The research group of Prof. Dr. Magdalena Gцtz at the Institute of Stem Cell Research of the GSF -- National Research Centre for Environment and Health, and the Ludwig Maximilians University, Munich, has achieved an additional step for the potential replacement of damaged brain cells after injury or disease: functional nerve cells can be generated from astroglia, a type of supportive cells in the brain by means of special regulator proteins.
