Scientists discover how an injured embryo can regenerate itself

More than 80 years have passed since the German scientist Hans Spemann conducted his famous experiment that laid the foundations for the field of embryonic development. After dividing a salamander embryo in half, Spemann noticed that one half - specifically, the half that gives rise to the salamander's 'belly' (ventral) starts to wither away.

New, previously unrecognized source of heart stem cells discovered

Researchers at Children's Hospital Boston are continuing to document the heart's earliest origins. Now, they have pinpointed a new, previously unrecognized group of stem cells that give rise to cardiomyocytes, or heart muscle cells. These stem cells, located in the surface of the heart, or epicardium, advance the hope of being able to regenerate injured heart tissue.

Australia to enter the race to clone human embryo cells for stem-cell research

Melbourne's Monash University may be granted the first licence in Australia to clone human embryo cells for stem-cell research.

Avoiding spleen removal for Cooley's anemia sufferers

Researchers from Weill Cornell Medical College may have discovered the precise role of a gene in one of the world's most common blood disorders, beta-thalassemia, commonly known as Cooley's anemia. Along with sickle-cell anemia, Cooley's anemia is the most commonly inherited disease in the world, affecting many people of Mediterranean descent, and 20 out of every 100,000 African-Americans. The World Health Organization estimates that between 50,000-100,000 children are born with the disease each year.

Killer competition: neurons duke it out for survival!

The developing nervous system makes far more nerve cells than are needed to ensure target organs and tissues are properly connected to the nervous system. As nerves connect to target organs, they somehow compete with each other resulting in some living and some dying.

Scientists produce stem cells from ordinary mouse skin cells

Researchers in the United States say they have produced a stem cell made from ordinary mouse skin cells which they have coaxed into becoming three different types of heart and blood cells in mice.

New model for embryonic limb development

A study led by a researcher at the University of Southern California has found a new model to explain how signals between cells in the embryo control limb development.

A diaphanous control during embryo formation

The research now published in the journal Development shows how Dia mutations in fruit flies embryos result in a serious of defects during morphogenesis (process by which cells differentiate into tissues and structures), including loss of adhesion, abnormal movements and even migration of cells from one tissue to another.

Newly identified gene may prompt pancreas cells to form

Before a pancreas is a pancreas, it?s part of the endoderm, one of three layers of cells in a developing embryo that eventually form its organs.

Grhelin hormone that controls hunger and appetite also linked to reduced fertility

Researchers at Yale School of Medicine have found that in-utero exposure to the hormone grhelin, a molecule that controls appetite and hunger and nutrition, can result in decreased fertility and fewer offspring.

Replacing absent microRNAs could make tumors less invasive, more treatable

One group of small, non-coding RNA molecules could serve as a marker to improve cancer staging and may also be able to convert some advanced tumors to more treatable stages, report a University of Chicago-based research team in the April 1, 2008, issue of the journal Genes & Development.
