First comprehensive profile of cell movement

Researchers at the University of California, San Diego (UCSD) School of Medicine have developed new technology which, combined with proteomics, the large-scale study of the structure and function of proteins and their functions, has allowed them to map an extensive network of the signaling proteins that control cell movement.

Scientists work out mechanism underlying asymmetric cell division in nematode worms

When a cell divides, normally the result is two identical daughter cells. In some cases however, cell division leads to two cells with different properties. This is called asymmetric cell division and plays an important role in embryonic development and the self-renewal of stem cells.

The convergence of embryonic and cancer signaling pathways: role in tumor cell plasticity

In earlier work, Northwestern University scientist Mary J.C. Hendrix and colleagues discovered that aggressive melanoma cells (but not normal skin cells nor less aggressive melanoma cells) contain specific proteins similar to those found in embryonic stem cells.

Respiratory control in insects: integration from the gene to the organism

Because of new imaging technology, researchers are getting a better understanding of a physiological paradox: how insects, which have a respiratory system built to provide quick access to a lot of oxygen, can survive for days without it.

Immune system disorder may be the cause of unexplained infertility

It's been a topic on Sex and the City and was rumored to be a problem for a popular sitcom star when she and her husband were trying to conceive.

Scientists gain insights into liver regeneration

The way the liver renews itself may be simpler than what scientists had been assuming.

Rep. Dave Weldon comments on stem therapy and type I diabetes

In yet another advance in adult stem cell therapy, the Journal of the American Medical Association (JAMA) today released a study in which 14 of 15 Juvenile Diabetes patients demonstrated significant improvement as a result of an adult stem cell treatment.

Scientists at Johns Hopkins discover Solitary protein

Working with fruit flies, scientists at Johns Hopkins have discovered a protein required for two neighboring cells to fuse and become one "super cell."

Scientists identify how development of different species uses same genes with distinct features

Biologists at New York University have identified how different species use common genes to control their early development and alter how these genes are used to accommodate their own features.

New procedure to estimate reproductive potential of individual embryos

To address the high rate of multiple births resulting from in-vitro-fertilization (IVF), researchers at Yale School of Medicine and McGill University have developed a procedure that estimates the reproductive potential of individual embryos, possibly leading to a decrease in multiple-infant births and a higher success rate in women undergoing IVF.

European patent on stem cells may be a possibility

As long as the research meets the usual requirements for a patent, isolated embryonic stem cells should be considered for both method and product patents.

Steroid use fails to boost pregnancy rates in infertility treatments

There is no clear benefit from a hormone commonly prescribed to enhance the effectiveness of infertility treatments, according to a new review of studies.

Enzyme important in fetal heart-cell failure - findings provide new targets for treatment

In almost all forms of heart failure, the heart begins to express genes that are normally only expressed in the fetal heart. Researchers have known for years that this fetal-gene reactivation happens, yet not what regulates it.

Researchers replace organ in mice using 'single-parent' stem cells

Researchers at the University of Pennsylvania School of Veterinary Medicine have derived uniparental embryonic stem cells - created from a single donor's eggs or two sperm - and, for the first time, successfully used them to repopulate a damaged organ with healthy cells in adult mice.
