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!

Through the identification of a gene's impact on a signaling pathway, scientists at Children's National Medical Center are making progress in understanding the mechanics of a key brain developmental process: growth and repair of white matter, known as myelination.

The study, published online in the September 2011 online edition of The Journal of Neuroscience, identified Sox17 as the gene that helps regulate the Wnt/beta-catenin signaling pathway during the transition of immature brain cells to a more mature brain cell coated with myelin.

"This is the first time the Sox17 gene has been identified as a regulator of the Wnt/beta-catenin pathway during myelination," said Li-Jin Chew, PhD, lead author of the study.

"Our findings indicate that loss of Sox17 over-stimulates the Wnt/beta-catenin pathway and keeps oligodendrocyte progenitor cells from maturing and producing myelin, potentially causing developmental disabilities in developing babies and children."

Myelin is the protective material around the axons of neurons. The mass of these types of ensheathed neurons are collectively called white matter.

White matter serves as the primary messaging "network" that conducts signals rapidly between gray matter areas. Without it, the brain does not function properly.

Myelination, or growth of white matter, in humans begins in utero at around 5 months of gestation and continues throughout the first two decades of life.

It can be impaired for a number of reasons, most commonly intrauterine infection, reduced or interrupted blood flow (impairing the delivery of oxygen and nutrients) to the forming infant brain, or perinatal injury. As a result, white matter doesn't develop the way that it should or is somehow damaged, resulting in mental retardation and developmental disabilities.

"From here we plan to look more closely at the parts of the pathway that Sox17 regulates. We'll be able to understand the crucial molecular events that occur during oligodendrocyte development and disease," states Vittorio Gallo, PhD, director of the Center for Neuroscience Research.

"This is an incredibly exciting discovery that puts us closer to figuring out the underlying cause of white matter diseases. It also means that we may eventually understand how we could influence these pathways and possibly ease white matter damage or deficiency in our patients."

Myelination, white matter growth and repair, and the study of complex mechanisms of prenatal brain development are a key focus of the Center for Neuroscience Research at Children's National, which also houses the White Matter Diseases Program, one of the largest clinical programs in the country for treating children with disorders that cause the brain's white matter to degenerate.

Children's National Medical Center in Washington, DC, has been serving the nation's children since 1870. Home to Children's Research Institute and the Sheikh Zayed Institute for Pediatric Surgical Innovation, Children's National is consistently ranked among the top pediatric hospitals by U.S.News & World Report and the Leapfrog Group. With 283 beds, more than 1,330 nurses, 550 physicians, and seven regional outpatient centers, Children's National is the only exclusive provider of acute pediatric services in the Washington metropolitan area. Children's National has been recognized by the American Nurses Credentialing Center as a Magnet® designated hospital, the highest level of recognition for nursing excellence that a medical center can achieve.
