Researchers capitalize on 'memories' of adult-derived stem cells for treatment of diabetes

Stem cells from early embryos can be coaxed into becoming a diverse array of specialized cells to revive and repair different areas of the body. Therapies based on these stem cells have long been contemplated for the treatment of diabetes, but have been held back by medical and ethical drawbacks.

New strategy may combat age-associated infertility and birth defects

A strategy that has been shown to reduce age-related health problems in several animal studies may also combat a major cause of age-associated infertility and birth defects.

Merck Serono announces recipients of second Grant for Fertility Innovation

Merck Serono, a division of Merck KGaA, Darmstadt, Germany, today announces the recipients of its second Grant for Fertility Innovation.

Cumulus cells can provide information about genetic and chromosomal status of eggs

At present, when a woman undergoes preimplantation genetic screening (PGS) in a fertility clinic, doctors are trying to select an egg or an embryo that is healthy and doesn't have a chromosome abnormality such as an extra copy of chromosome 21, which causes Down's syndrome. In order to establish this, they either have to biopsy a part of the egg called the polar body or remove a cell from the embryo for screening. Both procedures are expensive, invasive and can damage the egg or embryo.

Induced pluripotent cells may make embryonic stem cells unnecessary

For nearly two decades, the medical world and the American public have grappled with the lightning-rod topic of stem cells, in particular the controversy surrounding cells from human embryos. But when researchers four years ago successfully "reprogrammed" adult body cells to become stem cells, some thought the ethical debate was nearly over. Those redirected cells, known as induced pluripotent cells, or iPS cells, show potential as therapy.

Frozen embryo transfer may not adversely affect neonatal outcome

In the first study, French scientists looked at neonatal outcome in terms of mode of delivery, gestational age, preterm birth rate (less than 37 weeks of gestation), mean child measurements, low birth weight (less than 2,500g) and perinatal mortality. When comparing the cryo singletons to the fresh cohort, the scientists showed that mean birth weight, mean height and head circumference were lower in the fresh population.

EIM collects data on frozen oocyte retrieval cycles for the first time

Other important data the European IVF Monitoring group (EIM) on 2008 cycles and the International Committee Monitoring Assisted Reproductive Technologies (ICMART) on 2007 cycles highlighted were Sweden's low rate of multiple births - the lowest in the world - and Spain's 30 % share of egg donations in Europe.

Researchers investigate predictors for adverse outcome in IVF singletons

In Sweden almost 40 000 children have now been born after IVF, around 3 500 each year, and IVF children constitute 3% of all newborns. "This represents a large number of children and any adverse outcomes related to IVF are therefore a major public health issue," said Dr. Antonina Sazonova, from Sahlgrenska University Hospital, Gothenburg, Sweden, who carried out the research with colleagues from the hospital and from Lund University.

Study: 'Vanishing twin' linked to increased risk of congenital malformations

Professor Michael Davies will tell the annual meeting of the European Society of Human Reproduction and Embryology today that the "vanishing twin" phenomenon, in which only one child is born from a pregnancy that originally starts as a multiple pregnancy, is linked to a nearly two-fold increased risk in any congenital malformation and to a nearly three-fold risk of multiple malformations.

Cleavage stage embryo with aneuploidy can undergo genetic normalisation process

Professor William G. Kearns told the annual meeting of the European Society of Human Reproduction and Embryology that a three-day-old embryo with an incorrect number of chromosomes was capable of undergoing "a dynamic process of genetic normalisation" so that by day five, when it had developed to the blastocyst stage, it had become euploid, with the correct number of chromosomes.

Researchers discover crucial role of miR-206 in skeletal muscle development

Research led by the University of East Anglia has discovered the crucial role of a molecule in skeletal muscle development.

Research addresses chromosomal imbalance in embryos

Joint research between the University of Kent's Professor Darren Griffin, London Bridge Fertility Centre and BlueGnome Ltd has addressed chromosomal imbalance in embryos, a condition that is currently the major cause of pregnancy loss in IVF.

New model may help reduce multiple pregnancies in women

Dr Jan Holte told the annual meeting of the European Society for Human Reproduction and Embryology, that if this model were to be applied in all fertility clinics, it had the potential to reduce the twin rates to the level of just under two percent seen in the normal population. Already, another four clinics have started to use the model.

U-M researchers a step closer to developing treatments for aging and chronic diseases

As our bodies first form, developing cells are a lot like children put on the school bus with their names and addresses pinned to their shirts. The notes identify one as a future heart cell, another as a liver cell, a third as a neuron. And that's what they each grow up to be. But once those cells reach adulthood, changes to those original marching orders caused by aging, disease and other stressors like smoking can precipitate a kind of identity crisis, researchers at the University of Michigan Health System have found.

Low testosterone linked to varicoceles

As many as 15 percent of men have varicoceles, masses of enlarged and dilated veins in the testicles. There is new evidence that varicoceles, long known to be a cause of male infertility, interfere with the production of testosterone -- a crucial hormone to maintaining men's health. There is good news too: Microsurgery can increase testosterone levels in these men. Results of new research by physician-scientists at NewYork-Presbyterian Hospital/Weill Cornell Medical Center are in a recent edition of BJU International.

Scientists discover Sonic Hedgehog protein's mechanism of action

A scientific breakthrough by researchers at the Institut de recherches cliniques de Montréal (IRCM) will be published tomorrow in Developmental Cell, a scientific journal of the Cell Press group. Led by Dr. Frédéric Charron, the team of scientists discovered a new requirement for the proper functioning of the Sonic Hedgehog protein.

Key molecule of vascular system directs axons during neural circuit formation

Dr. Fr-d-ric Charron, researcher at the Institut de recherches cliniques de Montr-al (IRCM), and his team have shown for the first time that a key molecule of the vascular system directs axons during the formation of neural circuits.

Drug that makes the failing heart heal itself

Researchers have found that a drug can heal heart muscles in mice. Earlier it was considered that this damage to the heart is permanent but this new findings refutes earlier beliefs.
