Embryology is the study of the development of an embryo. An embryo is defined as any organism in an early stage well before birth or hatching, or in plants, before germination occurs.

Guidelines released to cover new embryo donation option for infertile couples

Surplus embryos created by couples who have undergone IVF treatment can now be donated to assist other infertile people have a child, as a result of new guidelines released in New Zealand.

Preliminary molecular diagram of the early stages of embryo formation

A team of genomic researchers headed by biologists at New York University's Center for Comparative Functional Genomics, in collaboration with researchers at Harvard University, the Max Planck Institute, and Cenix Biosciences, has mapped out a preliminary molecular diagram of the early stages of embryo formation, offering for the first time a global look at how a single cell begins its path into a multi-cellular organism.

Placental tissue could feasibly provide an abundant source of cells with the same potential to treat diseases as embryonic stem cells

Routinely discarded as medical waste, placental tissue could feasibly provide an abundant source of cells with the same potential to treat diseases and regenerate tissues as their more controversial counterparts, embryonic stem cells, suggests a University of Pittsburgh study to be published in the journal Stem Cells and available now as an early online publication in Stem Cells Express.

Babies born during famine are at higher risk of schizophrenia

A new study has found that malnutrition can harm mental as well as physical health, and babies born during famine are at higher risk of schizophrenia.

Arf gene prevents excessive growth of blood vessels in the developing eye

A gene better known for its role in preventing cancer also plays a key role in the developing embryo, where the gene prevents excessive growth of blood vessels, according to investigators at St. Jude Children's Research Hospital.

IVF treatment to restrict women to one embryo only each time

In order to avoid the dangers of multiple births, women having in vitro fertilisation may be limited to having just one embryo implanted at a time.

Single protein regulates secretion levels - helps stem cells become secretory cells

Johns Hopkins researchers have discovered that a single protein regulates secretion levels in the fruit fly's salivary gland and its skin-like outer layer.

Australian stem cell discovery hailed as a major medical and scientific development

Monash Institute of Medical Research (MIMR) senior scientist Dr Caroline Gargett's discovery of adult stem cells in the uterus that can be grown into bone, muscle, fat and cartilage, has been hailed as a major medical and scientific development by international reproduction experts.

Nerve cells can also release neurotransmitters outside of synapses

Every neurobiology textbook invariably states that nerve cells communicate with each other through synapses, the specialized cell-cell contacts found at the end of the cells' threadlike extensions. In the journal Science, researchers at the Salk Institute for Biological Sciences and the University of California at San Diego report that nerve cells, or neurons, may not have to rely on traditionally defined synapses to "talk" to each other.

Outer lining of the umbilical cord is a rich source of stem cells

CellResearch Corporation in Singapore and its team of scientists, headed by Chief Scientist, Dr Phan Toan Thang, have recently made a revolutionary discovery: that the outer lining of the umbilical cord is a rich source of stem cells.

X-ray crystallography images show how a protein called alpha-actinin performs molecular ballet

As a cell moves forward, physical stress on its skeleton triggers molecular fingers and arms to grasp each other in reinforcing links that stabilize the skeleton, according to images produced by investigators at St. Jude Children's Research Hospital.

Researchers find enzyme vital for controlling the early stages of cell death

Researchers at UT Southwestern Medical Center have found an enzyme vital for controlling the early stages of cell death - a beneficial and normal process when it works right, but malignant in a variety of cancers when it malfunctions.

Pregnancy and birth factors may determine likelihood of polycystic ovarian syndrome

New research suggests that the way baby girls develop in the womb may affect whether or not they develop polycystic ovarian syndrome (PCOS) as adults and the severity of the symptoms if they do.

Infertility may be becoming more of a man's problem than a woman's problem

Until now, approximately 40% of infertility cases have been linked to medical problems in men and 40% to medical problems in women, with the remaining 20% due to joint problems.

The potential benefit that IVF children bring to society far outweighs the cost of 'producing' them

Dr. Maria Granberg, from the Fertilitetscentrum, Göteborg, Sweden, told the conference that, although the total cost of IVF financed by health care systems in Nordic countries had increased over the last few years, it was still highly profitable to society.

Triplet pregnancies cost more than eight times as much as singleton pregnancies

Research in France has revealed that triplet pregnancies cost more than eight times as much as singleton pregnancies, and twin pregnancies cost more than three times as much, the 21st annual conference of the European Society of Human Reproduction and Embryology heard.

Chemicals found in everyday products and food have subtle but potentially damaging effects on sperm fertility

Professor Lynn Fraser told the 21st annual conference of the European Society of Human Reproduction and Embryology today (Wednesday), that her previous research had shown that certain chemicals known to mimic the female sex hormone, oestrogen, could individually affect the correct functioning of mouse sperm, but now her new research showed that when the chemicals were combined they had an even stronger effect.
