Embryos that are selected out as abnormal can undergo chromosomal modifications

Ms Tsvia Frumkin, from the Racine IVF unit, LIS Maternity Hospital, Tel Aviv Sourasky Medical Centre, Tel Aviv, Israel, will tell the conference that her team's findings meant that the results of preimplantation genetic screening (PGS) for chromosomal abnormalities were not always reliable and should be interpreted with caution.

Health of babies not affected by embryo screening

New research has shown that babies born after pre-implantation genetic diagnosis (PGD) are as healthy as those born after conventional IVF treatment.

Primary ciliary dyskinesia linked to heterotaxy

The same genetic defect that causes a rare respiratory disease may also lead to some types of congenital heart disease, according to a study from the University of North Carolina at Chapel Hill School of Medicine.

Researchers shed light on congenital diaphragmatic hernia

The diaphragm, a shelf of muscle that separates the chest cavity from the abdominal cavity, is critical to sustaining life.

Scientists look at slow-freezing techniques for human tissue

The goal is to make human eggs, ovarian tissue, blood vessels, even whole organs available when needed.

Embryonic stem cells can be created without eggs

Embryonic stem cells are unique because they can develop into virtually any kind of tissue type, an attribute called pluripotency.

Deleting gene important in embryo development leads to premature aging in mice

Researchers at the Abramson Family Cancer Research Institute of the University of Pennsylvania have found that deleting a gene important in embryo development leads to premature aging and loss of stem cell reservoirs in adult mice.

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.

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.
