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!

WHO Child Growth Charts

Researchers at Barrow Neurological Institute at St. Joseph's Hospital and Medical Center have identified a new pathway of stem cell activity in the brain that represents potential targets of brain injuries affecting newborns.

The recent study, which raises new questions of how the brain evolves, is published in the current issue of Nature, one of the world's most cited scientific journals.

Nader Sanai, MD, director of Barrow's Brain Tumor Research Center, led this study, which is the first developmental study of human neural stem cells in a region of the brain called the subventricular zone, the tissue structure in which brain stem cells reside.

Also participating in the study were researchers from University of California San Francisco and the University of Valencia in Spain.

The findings revealed that there is a pathway of young migrating neurons targeting the prefrontal cortex of the human brain in the first few months of life. After the first year of life, the subventricular zone of the brain slows down, tapering production of new brain cells by the time a child is 18-months and then to nearly zero by age two.

This revelation settles conflicting prior reports that suggested that human neural stem cell cells remain highly active into adulthood.

"In the first few months of life, we identified streams of newly-generated cells from the subventricular portion of the brain moving toward the frontal cortex," says Dr. Sanai.

"The existence of this new pathway, which has no known counterpart in all other studied vertebrates, raises questions about the mechanics of how the human brain develops and has evolved."

Researchers believe this study holds important implications for the understanding of neonatal brain diseases that can cause death or devastating, life-long brain damage.

These conditions include germinal matrix hemorrhages, the most common type of brain hemorrhage that occurs in infants; and perinatal hypoxic – ischaemic injuries, exposure to low oxygen and decreased blood flow that can lead to diseases such as cerebral palsy and seizure disorders.

"The first year of human life has a window of vulnerability, as well as tremendous opportunity, for the brain," says Dr. Sanai.

"It's a period of incredible growth, organization, and flexibility, as fresh neural connections are created, broken, and remade. A better understanding of how things can go wrong in that critical period could ultimately improve the chances that things will go right."
