Embryonic stem cell differentiation: emergence of a new era in biology and medicine
Recent advances in our understanding of ES cell differentiation have provided new insights essential for establishing ES cell-based developmental models and for the generation of clinically relevant populations for cell therapy.

Early stages of neural crest ontogeny: formation and regulation of cell delamination
A summary of recent advances in the early stages of crest ontogeny that comprise specification of epithelial progenitors to a neural crest fate and the onset of neural crest migration.

In early embryos, cilia get the message across
Having your heart in the right place usually means having it located on the left side of your body.

Are IVF embryos starved of a vital ingredient?
The lack of natural growth factors in the fluid in which IVF embryos are grown could have lifelong effects on people conceived this way.

Many couples choose to donate surplus embryos for stem cell research
Nearly 50% of couples who were interviewed at least 3 years after undergoing in vitro fertilization chose to donate their surplus, stored embryos for stem cell research

The ultimate spa: embryonic body wash controls left-right development
Humans and other animals may appear to be symmetrical on the outside, but symmetry is only skin deep.

Researchers model embryo implantation and tumour metastasis in fruit flies
A research team discovered that a protein previously linked to mammalian embryo implantation, as well as tumour metastasis, plays similar roles in fruit fly development

Jefferson researchers uncover biochemical clues to how cells migrate in embryos
The work offers potential insights into disease processes, including cancer

Who laid the first egg? An update
Scientists move a step closer to linking embryos of earth's first animals and their adult form

UNC study pinpoints gene crucial for female embryo survival
Gene keeps paternal X chromosome inactive

When One Gene Has Two Roles, Its Second Function May Be Missed
Scientists found that the same master gene that controls development of all of the body's blood cells is later activated in other cells of the embryo to form the genitourinary tract.

Most clones doomed from the start, according to Temple University embryologist
Until scientists can improve the early development of cloned embryos, cloning will remain marginally successful

Mouse study identifies protective mechanism against alcohol-induced embryo toxicity
Researchers have identified a mechanism by which the eight amino acid peptide NAP, an active fragment of a neuroprotective brain protein, protects against alcohol-induced embryo toxicity and growth retardation in mice.

Researchers Discover Initial Steps In Development Of Taste
Of the five senses, taste is one of the least understood, but now researchers have come one step closer to understanding how the sense of taste develops.

The molecular basis of transdifferentiation
In the present review the authors discussed the identification of selector, or master switch, genes as well as examples of transdifferentiation...

Researchers Discover How A Key Dietary Vitamin Is Absorbed
Researchers at the Albert Einstein College of Medicine of Yeshiva University have found the mechanism by which the B vitamin folate--a crucially important nutrient--is absorbed by the intestinal tract.

Why Embryos Need A Good Diet
A thick-coated vole and a man with cardiovascular disease have something in common: both are doing what their mothers told them.

Multiple-birth Babies, Boys Have Higher Risk Of Defects
Twins, triplets and other multiples have a nearly 50 percent greater chance of being born with birth defects, and boys tend to be more at risk than girls, according to two population-based studies

Veterinary Researchers Seek Secret To Reversing Birth Defects
Fetal development is a highly choreographed process. But all too often it is disrupted when a mother is exposed to a teratogen an agent known to cause a variety of birth defects.

Polarity and intracellular compartmentalization of Drosophila neurons
Proper neuronal function depends on forming three primary subcellular compartments: axons, dendrites, and -generic drug-.
