Scientists develop new method to produce embryos from non-egg cells

Scientists have shown for the first time that embryos can be made from non-egg cells, a discovery that challenges two centuries of received wisdom.

Researchers suggest need for human studies to examine effects of cannabinoid use during pregnancy

In this new era of legalized marijuana, far too little research has been conducted on the effect of cannabis on the development of human embryos, say researchers at Georgetown University Medical Center who scoured medical literature on the topic and found what they say is worrisome animal research.

Researchers link RHOX gene mutations to infertility in men

The underlying cause of male infertility is unknown for 30 percent of cases. In a pair of new studies, researchers at University of California San Diego School of Medicine determined that the reproductive homeobox (RHOX) family of transcription factors — regulatory proteins that activate some genes and inactivate others — drive the development of stem cells in the testes in mice.

Researchers identify new immune cell that protects mice from lung infections during chemotherapy

St. Jude Children's Research Hospital investigators have identified a new form of an immune cell that protected mice from life-threatening lung infections under conditions that mimic cancer chemotherapy.

Synthego introduces CRISPRevolution synthetic sgRNA kit for fast, high-throughput gene editing

Synthego, a leading provider of genome engineering solutions, today announces the world’s first synthetic single guide RNA (sgRNA) CRISPR genome editing kit.

Researchers use novel technique to unravel key mystery of earliest stage of development

A Ludwig Cancer Research study published online September 14th in Nature reports a novel technique to map specific chemical (or "epigenetic") modifications made to the protein packaging of DNA using a small population of cells.

Researchers identify mutant traits in mouse for many human disease genes

About one-third of all genes in the mammalian genome are essential for life. An international, multi-institutional research collaboration identified, for the first time, mutant traits in the mouse for 52 human disease genes, which significantly contributes to the understanding of the genetic bases for some human diseases, including cardiovascular defects, spina bifida, and metabolic disorders, among many others. The study was published this week in Nature.

Stiff, hypoxic regions of tumors trigger cancer progression

When Hippocrates first described cancer around 400 B.C., he referred to the disease's telltale tumors as "karkinos" -- the Greek word for crab.

Researchers develop novel technique to generate hiNSCs for multiple tissue engineering applications

Tufts University researchers have discovered a new technique for generating rapidly-differentiating human neural stem cells for use in a variety of tissue engineering applications, including a three-dimensional model of the human brain, according to a paper published today in Stem Cell Reports

Steroids for treating infertility in women may have harmful effects on pregnancy and child

Researchers at the University of Adelaide are urging doctors and patients to refrain from using a specific steroid treatment to treat infertility in women unless clinically indicated, because of its links to miscarriage, preterm birth and birth defects.

Skin cells derived from autistic donors grow faster than those from control subjects

Brain cells grow faster in children with some forms of autism due to distinct changes in core cell signaling patterns, according to research from the laboratory of Anthony Wynshaw-Boris, MD, PhD, chair of the department of genetics and genome sciences at Case Western Reserve University School of Medicine.

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.
