Ovaries of reproductive-age women possess egg precursor cells that can mature into eggs

OvaScience, a fertility company focused on the discovery, development and commercialization of novel treatments for infertility, today announced the publication of results demonstrating that ovaries of reproductive-age women possess egg precursor cells that can mature into eggs.

MGH scientists isolate OSCs from ovaries of reproductive age women

For the first time, Massachusetts General Hospital (MGH) researchers have isolated egg-producing stem cells from the ovaries of reproductive age women and shown these cells can produce what appear to be normal egg cells or oocytes.

Rotational motion plays a critical role in ability of breast cells to form acini

In a study that holds major implications for breast cancer research as well as basic cell biology, scientists with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory have discovered a rotational motion that plays a critical role in the ability of breast cells to form the spherical structures in the mammary gland known as acini.

Study on miscarriage rates following IVF treatment with frozen thawed embryos

Elsevier, a world-leading provider of scientific, technical and medical information products and services today announced the publication of an article in the December issue of Reproductive BioMedicine Online (www.rbmonline.com) about miscarriage rates following IVF treatment with frozen thawed embryos which may revolutionize clinical and laboratory practice.

Established human embryonic cell lines vary from newly derived stem cell lines

Established human embryonic cell lines, including those approved for federal research funding under former President George W. Bush, are different than newly derived human embryonic stem cell lines, according to a study by UCLA stem cell researchers.

Genetics & IVF Institute now offers 24 Chromosome Microarray

The Genetics & IVF Institute is now offering 24 Chromosome Microarray, which is a new, comprehensive test used as part of an IVF cycle to evaluate the number of chromosomes present in an embryo before it is transferred to the mother.

Thriving stem cells created by cloning technique

In a breakthrough that has been debated and awaited for long, scientists have finally derived colonies of embryonic stem cells from human embryos created using cloning technology.

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.

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.

Infertility centers under scrutiny

Private infertility treatment centers in Britain are set to come under increased scrutiny. These centers have come under scrutiny for exploiting vulnerable couples with their high fees and exaggerated success story claims.

New research finds differences in cell fate commitment during embryonic development in mammals

New research shows that all not mammals are created equal. In fact, this work shows that the animals most commonly used by scientists to study mammalian genetics -- mice -- develop unusually quickly and may not always be representative of embryonic development in other mammals.

Miracle boy born after new infertility therapy

A Lancashire couple Andrew and Louise Riley have been blessed with a “miracle baby boy” thanks to a pioneering new genetic screening process. Elliott Riley was born just after Christmas after the Rileys opted for a relatively new technique called array comparative genomic hybridisation (CGH) after 10 years of infertility treatments. Mrs. Riley, 37, and her husband, 39, said they were delighted to welcome Elliott on December 30.

Vitrolife receives FDA approval for RapitVit Blast and RapidWarm Blast vitrification products

Vitrolife has received approval from the U.S. Food and Drug Administration, FDA, the equivalent of the Swedish Medical Products Agency, for the products RapitVit™ Blast and RapidWarm™ Blast. So-called 510(k) clearance has been obtained for these products, which are used for so-called vitrification, the rapid freezing and thawing of blastocysts (embryos days 5-7 after fertilization). Vitrolife has since before approved products for vitrification of embryos in an earlier stage of the fertilization (embryos day 2-3 after fertilization).

New direct labeling system for oocytes, embryos

Researchers from the Department of Cell Biology, Physiology and Immunology at Universitat Autònoma de Barcelona (UAB), in collaboration with researchers from the Institute of Microelectronics of Barcelona (IMB-CNM) of the Spanish National Research Council (CSIC), have developed an identification system for oocytes and embryos in which each can be individually tagged using silicone barcodes.

New set of guidelines for Preimplantation Genetic Diagnosis Screening

The European Society of Human Reproduction and Embryology (ESHRE) has published a set of guidelines for best practice Preimplantation Genetic Diagnosis (PGD)/Screening (PGS) to give information and guidance to potential and existing PGD centres.

Noninvasive embryo assessment technology may improve success rates for in vitro fertilization procedures

Auxogyn, Inc., a privately held medical technology company focused on women's reproductive health, today announced that it acquired an exclusive license from Stanford University to develop a set of products that may allow medical practitioners in the field of assisted reproduction to significantly improve the effectiveness of in vitro fertilization (IVF) procedures.

Researchers identify ways to predict embryonic developmental success

Two-thirds of all human embryos fail to develop successfully. Now, in a new study, researchers at the Stanford University School of Medicine have shown that they can predict with 93 percent certainty which fertilized eggs will make it to a critical developmental milestone and which will stall and die. The findings are important to the understanding of the fundamentals of human development at the earliest stages, which have largely remained a mystery despite the attention given to human embryonic stem cell research.

Overweight women undertaking ART at increased risk of miscarriage

Being overweight leads to a greater risk of miscarriage for patients undergoing assisted reproductive technology (ART), the 26th annual conference of the European Society of Human Reproduction and Embryology heard today (Monday). Dr. Vivian Rittenberg, a Clinical Fellow in the Assisted Conception Unit, Guy's and St. Thomas' Hospital NHS Foundation Trust, London, UK, said that her research provided additional evidence to show that increased body mass index (BMI) was independently associated with a higher miscarriage rate after IVF or ICSI treatment.
