Advanced imaging technique could help select embryos most viable for successful pregnancy

Researchers at the University of Adelaide have successfully trialed a new technique that could aid the process of choosing the "best" embryo for implantation, helping to boost the chances of pregnancy success from the very first IVF cycle.

Study reveals how pluripotency differs among mice, monkeys, and humans

Not too shabby, humans. New research shows that certain primate stem cells have pluripotency superior to some types derived from mice.

New biomaterial allows scientists to study how stem cells sense stiffness of surrounding environment

A new biomaterial can be used to study how and when stem cells sense the mechanics of their surrounding environment, found a team led by Robert Mauck, PhD, the Mary Black Ralston Professor for Education and Research in Orthopaedic Surgery, in the Perelman School of Medicine at the University of Pennsylvania.

Assigning barcode to stem cells makes it possible to monitor large blood cell populations

By assigning a barcode to stem cells, researchers at Lund University in Sweden have made it possible to monitor large blood cell populations as well as individual blood cells, and study the changes over time.

Preimplantation genetic screening using next generation sequencing: an interview with Dr Luis Alcaraz

PGS, Preimplantation Genetic Screening, is a genetic test that analyses biopsied cells from embryos produced by in vitro fertilization (IVF) techniques. PGS determines whether the embryos are chromosomally normal (euploid) or not (aneuploid), thus giving the chance to transfer chromosomally normal embryos that are more apt to successfully implant and develop into a pregnancy.

Scientists discover less invasive, cheaper technique to improve woman's chances of becoming pregnant

For those facing infertility, IVF has long been the established option to have a baby. Now Australian and Belgian medical scientists have discovered how to improve a woman's chances of becoming pregnant using a less invasive and cheaper alternative.

Umbilical cells from babies of obese mothers show impaired expression of vital genes regulating metabolism

Scientists have long known that infants born to women who are obese show higher risks of obesity, but they don't fully understand what boosts those risks.

New fluorescence microscopy approach improves image resolution by merging three views into one

Researchers have developed a new fluorescence microscopy approach that significantly improves image resolution by acquiring three views of a sample at the same time. Their new method is particularly useful for watching the dynamics of biological processes, which can provide insights into how healthy cells work and what goes wrong when diseases occur.

New study shows frozen embryo transfer safer, more successful in women with PCOS

Women with polycystic ovary syndrome (PCOS) who receive frozen embryos during in vitro fertilization have safer and more successful pregnancies than those who get fresh embryos, according to the results of a recent collaboration between Penn State College of Medicine and Chinese researchers.

UH biologists developing strategies to help regenerate heart muscle cell formation

Cardiovascular diseases are the leading cause of death in the U.S. With one in every four deaths occurring each year, the five-year survival rate after a heart attack is worse than most cancers.

Whitehead Institute researchers identify cellular mechanisms involved in pre-mouth array formation

Whitehead Institute researchers have identified the pre-mouth array--an area of the developing face in embryonic frogs--that "unzips" to surround the mouth opening. Their work highlights the precision necessary to create the mouth and identifies the cellular mechanisms that drive its formation.

Scientist receives $1.7 million grant to study how early life toxic exposures predispose to diabetes

Some studies indicate that early life exposure to pollutants such as PCBs and phthalates can predispose people to disease. Now environmental scientist Alicia Timme-Laragy at the University of Massachusetts Amherst has received a five-year, $1.7 million grant from the National Institute of Environmental Health Sciences for a multi-level study of early life exposure to environmental contaminants and aberrant pancreas development, which may predispose one to diabetes.

New findings on microcephaly may offer clues to explore how Zika virus disrupts brain development

Long before Zika virus made it a household word, the birth defect called microcephaly puzzled scientists and doctors -- even as it changed the lives of the babies born with it during the pre-Zika era.

Scientists test endometrial scratching technique in first-time IVF attempters

A NEW simple procedure which involves gently scratching the lining of the womb in the month before IVF treatment, potentially improving treatment success, is being tested on first-time IVF attempters in a groundbreaking study.

Study finds mutations in three new genes can cause rare syndromic CHD disorders

Researchers at The University of Nottingham have been involved in one of the largest international studies of congenital heart disease, which has discovered gene mutations linked to three new rare congenital heart disorders (CHD).

Male hormones can reverse biological drivers of aging, study shows

Telomerase, an enzyme naturally found in the human organism, is the closest of all known substances to a "cellular elixir of youth." In a recent study, Brazilian and US researchers show that sex hormones can stimulate production of this enzyme.

Key gene controls ability of adult stem cells to regenerate muscle after injury, study finds

A key gene enables the repair of injured muscle throughout life. This is the finding of a study in mice led by researchers at NYU Langone Medical Center and the University of Colorado at Boulder, and published online July 21 in Cell Reports.

Enhancers can boost frequency of transcriptional bursting, study shows

A new study by researchers at Princeton University suggests that sporadic bursts of gene activity may be important features of genetic regulation rather than just occasional mishaps.

Breakthrough research shows cellular stress could be key to variety of birth defects

For the first time, scientists believe they've discovered a cause of multiple types of birth defects triggered by environmental stresses.

Experts propose guidelines to offer clarity for disputes over frozen embryos

In at least 11 cases over the last 24 years, including the appeal of a Missouri case heard in June, U.S. courts have grappled with difficult arguments between men and women who fertilized and froze embryos together, but then disagreed about whether they should be gestated and born.
