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.

New technique could give a preview of which eggs are likely to make the most viable embryos

Given the stakes of in vitro fertilization, prospective parents and their doctors need the best information they can get about the eggs they will extract, attempt to fertilize, and implant. New research at Brown University and Women & Infants Hospital of Rhode Island has found a way to see which genes each egg cell is expressing without harming it.

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.

Three Georgia Tech projects to receive NSF's EFRI grants

The National Science Foundation (NSF) has awarded $6 million to fund three projects involving researchers from the Georgia Institute of Technology. Each four-year, $2 million grant was awarded through the NSF's Division of Emerging Frontiers in Research and Innovation.

Lin28/let-7 pathway plays an unexpected key role in type 2 diabetes

A pathway activated in cancer plays an unexpected key role in metabolic diseases like type 2 diabetes, according to a study by researchers at Children's Hospital Boston. Evidence that the Lin28/let-7 pathway influences the cellular response to glucose provides a unifying theme to perplexing data that associates human genetic variation with diabetes risk.

Researchers analyse effects of BPA in an in-vitro culture of ovaries

Researchers at Universitat Aut-noma de Barcelona, in collaboration with the Vall d'Hebron Hospital Fetal Tissue Bank, the Department of Gynaecology and the Research Unit of Paediatric Endocrinology, analysed the effects of Bisphenol A (BPA), a polymer widely used to manufacture plastics, in an in vitro culture of ovaries.

Researchers show how the body rids itself of damage when needed to reproduce and create new life

Although the body is constantly replacing cells and cell constituents, damage and imperfections accumulate over time. Cleanup efforts are saved for when it really matters. Researchers from the University of Gothenburg, Sweden, are able to show how the body rids itself of damage when it is time to reproduce and create new life.

Scientists discover crucial connection in skin formation

Skin is the body's armor, protecting us from disease agents, injury, excessive water loss, and cold and heat. Yet mutations in a single gene, the gene for the protein p63, cause numerous diseases and malformations of the uppermost layer of skin - the epidermis - and other tissues. In the epidermis, these range from skin cancers to dysplasias that cause cracking, bleeding, infection, and discoloration.

Water plays a decisive role in biologically active enzyme substrate compounds

In biologically active enzyme substrate compounds, as can be found in medicines, water plays a more decisive role than has been imagined up to now. The surrounding water acts like an "adhesive", in order to keep the substrate at the right place on an enzyme.

Rac1 protein triggers growth of long 'legs' that could propel melanoma cells to spread

Cancer Research UK scientists have discovered that a protein called Rac1 prompts pigment cells to sprout long 'legs' that could propel skin cancer cells, allowing them to spread, according to research published in Developmental Cell today.

Single UV laser pulse simultaneously zaps away biological tissue at multiple points

Researchers at Vanderbilt University have developed a new technique that uses a single UV laser pulse to zap away biological tissue at multiple points simultaneously, a method that could help scientists study the mechanical forces at work as organisms grow and change shape.

Pancreatic mesenchyme plays central role in the formation of mature beta cells

A somewhat mysterious soft tissue found in the fetus during early development in the womb plays a pivotal role in the formation of mature beta cells the sole source of the body's insulin. This discovery, made by scientists at University of California, San Francisco (UCSF) and Texas A&M University, may lead to new ways of addressing Type 1 and Type 2 diabetes.

Scientists discover highly conserved mechanism governing brain development

If you think today's political rhetoric is overheated, imagine what goes on inside a vertebrate embryo. There, two armies whose agendas are poles apart, engage in a battle with consequences much more dire than whether the economy will recover---- they are battling for whether you (or frogs or chickens) will have a forebrain.

New fertilized cells narrowly avoid degenerating into fatal chaos

Research based at Princeton University has revealed that newly fertilized cells only narrowly avoid degenerating into fatal chaos. At the same time, scientists have discovered that embryos have acquired a mechanism to contain this dangerous instability, a finding that could help biologists unravel other mysteries about the first hours of life.

Scientists show how scaling works in developing fruit fly wings

Weizmann Institute scientists have added a significant piece to the puzzle of scaling - how patterns stay in sync with size as an embryo or organism grows and develops. In a new study appearing in Current Biology, Institute scientists Profs.

Semaphorin-PlexinD1 signaling pathway shows promise as therapeutic target for cancer treatment

In a new study published in the August 16th issue of Developmental Cell, researchers at NYU Langone Medical Center identified a molecular mechanism that guarantees that new blood vessels form in the right place and with the proper abundance.

Scientists gain new insight on role of stem cells in embryonic heart development

Scientists at the Gladstone Institutes have gained new insight into the delicate relationship between two proteins that, when out of balance, can prevent the normal development of stem cells in the heart and may also be important in some types of cancer.

Researchers explain why vertebrate intestines are so predictably loopy

Between conception and birth, the human gut grows more than two meters long, looping and coiling within the tiny abdomen. Within a given species, the developing vertebrate gut always loops into the same formation-however, until now, it has not been clear why.

Study: miR-200s play a paradoxical role in metastatic cancer development

While they may be small in size, a family of tiny molecules called microRNAs could potentially play a large role in the process of cancer metastasis, or the spread of cancer from one area of the body to another.

Roadmap to overcome obstacles for using induced pluripotent stem cells

The possibility of developing stem cells from a patient's own skin and using them to treat conditions as diverse as Parkinson's disease, Alzheimer's disease and cancer has generated tremendous excitement in the stem cell research community in recent years. Such therapies would avoid the controversial need for using stem cells derived from human embryos, and in theory, also bypass immunological problems inherent in using cells from one person to treat another.
