Oscillation of gene activity may underlie how embryos grow in proportion

From a single-cell egg to a fully functional body: as embryos develop and grow, they must form organs that are in proportion to the overall size of the embryo. The exact mechanism underlying this fundamental characteristic, called scaling, is still unclear. However, a team of researchers from EMBL Heidelberg is now one step closer to understanding it.

IRCM study identifies mechanism responsible for generation of fingers and toes

Dr. Marie Kmita and her research team at the IRCM contributed to a multidisciplinary research project that identified the mechanism responsible for generating our fingers and toes, and revealed the importance of gene regulation in the transition of fins to limbs during evolution.

Researchers examine impact of exercise on mare reproductive health and embryo transfer

In the latest issue of the Journal of Animal Science, researchers at Clemson University and the University of Florida examine the impact of exercise on mare reproductive health and embryo transfer.

Scientists develop MitoFish for in vivo studies of mitochondria transport in nerve cells

Scientists have demonstrated a new way to investigate mechanisms at work in Alzheimer's and other neurodegenerative diseases, which also could prove useful in the search for effective drugs. For new insights, they turned to the zebrafish, which is transparent in the early stages of its life. The researchers developed a transgenic variety, the "MitoFish," that enables them to see - within individual neurons of living animals - how brain diseases disturb the transport of mitochondria, the power plants of the cell.

New method promises to boost stem cell production in laboratory

A new method for generating stem cells from mature cells promises to boost stem cell production in the laboratory, helping to remove a barrier to regenerative medicine therapies that would replace damaged or unhealthy body tissues.

microRNAs play an important role during embryonic development

Sanford-Burnham researchers discover that microRNAs play an important role in germ layer formation-the process that determines which cells become which organs during embryonic development

Longer looks: Are 'pods' the solution to our long-term care crisis?; A Liver transplant in the nick of time; Pro-life activists and the abortion drop

In November 2006, when Clara Marshall began suffering from the effects of dementia, her family moved her into ... an assisted living home in Vancouver, Wash. ... just five months into her stay, Ms. Marshall, 81, was found dead in her room apparently strangled after getting her neck caught in side rails used to prevent her from rolling out of bed.

Gadd45g protein essential in initiating development of male sex organs

Scientists at the Institute of Molecular Biology (IMB) in Mainz have identified a protein essential for initiating the development of male sex organs. Loss of the gene Gadd45g results in complete sex reversal of male mice, making them appear female.

Overexpressed enzyme contributes to development of preeclampsia

Preeclampsia is a serious complication of pregnancy and the major cause of death for both mother and child in Europe and the U.S. It affects about one in 20 pregnancies. The main symptoms are high blood pressure and protein in the urine.

Important knowledge about how stem cells develop best into insulin-producing cells

Scientists from The Danish Stem Cell Center (DanStem) at the University of Copenhagen are contributing important knowledge about how stem cells develop best into insulin-producing cells. In the long term this new knowledge can improve diabetes treatment with cell therapy.

IRCM researchers discover a nerve cell's internal clock

A team of IRCM researchers, led by Dr. Fr-d-ric Charron, recently uncovered a nerve cell's internal clock, used during embryonic development.

Pancreas stem cells can be turned into insulin producing cells

Stem cells in the adult pancreas have been identified that can be turned into insulin producing cells, a finding that means people with type 1 diabetes might one day be able to regenerate their own insulin-producing cells.

Auto-injector developed for women undergoing fertility treatment

A new auto-injector concept has been designed by innovative product development firm Cambridge Consultants in a bid to ease the trauma for women undergoing fertility treatment.

Caltech-led team discovers enzyme responsible for neural crest cell development

During the early developmental stages of vertebrates-animals that have a backbone and spinal column, including humans-cells undergo extensive rearrangements, and some cells migrate over large distances to populate particular areas and assume novel roles as differentiated cell types.

Research roundup: Lowering health costs of the poorest sick; Local variations in health spending

Olmstead County, Minn., which earlier required just restaurants to be smoke-free, enacted a law in 2007 that banned smoking in all workplaces. Researchers reported "a substantial decline in the incidence of MI from 18 months before the smoke-free restaurant law was implemented to 18 months after the comprehensive smoke-free workplace law was implemented 5 years later.

Scientists find new way to unlock cells' destinies

Scientists have discovered that breaking a biological signaling system in an embryo allows them to change the destiny of a cell.

Technology creates 3-D map of stresses linked to malformed structures

Researchers at Case Western Reserve University have found a way to create three-dimensional maps of the stress that circulating blood places on the developing heart in an animal model - a key to understanding triggers of heart defects.

IVF process negatively impacts women’s sexual relationships

An Indiana University study has found that women undergoing in-vitro fertilization report that the process of infertility treatment has many negative impacts on their sexual relationship with their partner. Little attention has been given to the sexual dynamics of couples as they navigate infertility and treatments such as IVF, despite the important role that sex plays in a couple's attempt to conceive a child.

Idea of nuclear reprogramming holds promise for repairing damaged tissue

The idea of taking a mature cell and removing its identity (nuclear reprogramming) so that it can then become any kind of cell, holds great promise for repairing damaged tissue or replacing bone marrow after chemotherapy.

Zebrafish model can test unique individual genetic differences in humans

The zebrafish is a potential tool for testing one class of unique individual genetic differences found in humans, and may yield information helpful for the emerging field of personalized medicine, according to a team led by Penn State College of Medicine scientists. The differences, or mutations, in question create minor changes in amino acids -- the building blocks of DNA -- from person to person.
