Welcome to The Visible Embryo, a comprehensive educational resource on human development from conception to birth.

The Visible Embryo provides visual references for changes in fetal development throughout pregnancy and can be navigated via fetal development or maternal changes.

The National Institutes of Child Health and Human Development awarded Phase I and Phase II Small Business Innovative Research Grants to develop The Visible Embryo. Initally designed to evaluate the internet as a teaching tool for first year medical students, The Visible Embryo is linked to over 600 educational institutions and is viewed by more than ' million visitors each month.


WHO International Clinical Trials Registry Platform
The World Health Organization (WHO) has created a new Web site to help researchers, doctors and patients obtain reliable information on high-quality clinical trials. Now you can go to one website and search all registers to identify clinical trial research underway around the world!

"We hope to inform the development of choline intake recommendations for pregnant women that ensure optimal fetal development and reduce the risk of stress-related diseases throughout the life of the child,"

Sick from Stress? Blame Mom and Epigenetics

If you're sick from stress, new research suggests that what your mother ate—or didn't eat—may be part of the cause

New research suggests that choline supplements for pregnant women lowers cortisol in the baby by changing the epigenetic expression of genes involved in cortisol production. The report appears in the August 2012 issue of the FASEB journal


The report shows that choline intake that is
higher than what is generally recommended
during pregnancy may improve
how a child responds to stress.


These improvements are the result ofepigenetic changes that ultimately lead to lower cortisol levels.


Epigenetic changes affect how a gene functions,
even if the gene itself is not changed.
Lowering cortisol is important as high levels
of cortisol are linked to a wide range of problems
ranging from mental health to metabolic
and cardiovascular disorders.


"We hope that our data will inform the development of choline intake recommendations for pregnant women that ensure optimal fetal development and reduce the risk of stress-related diseases throughout the life of the child," said Marie A. Caudill, Ph.D., a researcher involved in the work from the Division of Nutritional Sciences and Genomics at Cornell University in Ithaca, New York.

To make this discovery, Caudill and colleagues conducted a 12-week study involving pregnant women in their third trimester who consumed either the control diet providing 480 mg choline per day, a level that approximates current dietary recommendations, or the treatment diet which provided 930 mg choline per day.

Maternal blood, cord blood and placenta tissue were collected to measure the blood levels of cortisol, the expression levels of genes that regulate cortisol, and the number of methyl groups attached to the DNA of the cortisol regulating genes (the epigenetic changes). Those from mothers who consumed the higher levels of choline showed reduced levels of cortisol.

"Depending on the relationship, one's mother can either produce stress or relieve it. This report shows that her effect on stress begins even before birth. The importance of choline cannot be overstated as we continue to unravel the role it plays in human health and development." says Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal.

The FASEB Journal (http://www.fasebj.org) is published by the Federation of the American Societies for Experimental Biology (FASEB) and is among the most cited biology journals worldwide according to the Institute for Scientific Information. In 2010, the journal was recognized by the Special Libraries Association as one of the top 100 most influential biomedical journals of the past century. FASEB is composed of 26 societies with more than 100,000 members, making it the largest coalition of biomedical research associations in the United States. Celebrating 100 Years of Advancing the Life Sciences in 2012, FASEB is rededicating its efforts to advance health and well-being by promoting progress and education in biological and biomedical sciences through service to our member societies and collaborative advocacy.
