Ethically universal stem cell lines

Human embryonic stem cells (hESC), those very young cells that are a biological blank slate, have the potential to become more specialized, contributing to the workings of a wide variety of organs and tissues.

New discoveries on genes implicated in Fanconi anaemia

An international research consortium, which included the participation of the Mutagnesi Group from the UAB, has made outstanding progress in the study of Fanconi anaemia.

New protocols to understand embryos, clones, stem cells

Cloning, X-chromosome inactivation, stem cells, and embryogenesis are hot areas of research at the moment, and protocols featured in this month's release of Cold Spring Harbor Protocols will aid these studies.

Scientists develop a more human-like mouse model of cancer

A team led by Dana-Farber Cancer Institute scientists has developed a more human-like mouse model of cancer they say will aid the search for cancer-causing genes and improve the predictive value of laboratory drug testing.

Breakthrough in understanding how cancers spread

The University of Manchester study used embryonic stem (ES) cells to investigate how some tumours are able to migrate to other parts of the body, which makes the treatment of cancer much more difficult.

Biologist hopes mosquito can break viral chain

Most people do their best to avoid mosquitoes. But this summer Rollie Clem will play the wary host to his own homegrown swarm of Aedes aegypti, the yellow fever mosquito. He's made a room ready for them, and even a menu.

Glucose plays a key role in enabling healthy beta cells

A key aspect of how embryos create the cells which secrete insulin is revealed in a new study published in the Journal of Biological Chemistry.

Hair loss may be reversible

Scientists who have helped create new hair cells on the skin of mice say hair loss may be reversible.

Fifteen different pesticides in the organisms of pregnant women

Human beings are directly responsible for more than 110,000 chemical substances which have been generated since the Industrial Revolution.

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.
