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 one million visitors each month.

Today, The Visible Embryo is linked to over 600 educational institutions and is viewed by more than 1 million visitors each month. The field of early embryology has grown to include the identification of the stem cell as not only critical to organogenesis in the embryo, but equally critical to organ function and repair in the adult human. The identification and understanding of genetic malfunction, inflammatory responses, and the progression in chronic disease, begins with a grounding in primary cellular and systemic functions manifested in the study of the early embryo.

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!

Recent national surveys indicate that 14 percent of American adolescents now have pre-hypertension or hypertension. "Obesity is driving the trend but our findings suggest that environmental factors may also be a part of the problem," says Dr.Leonardo Trasande.

Chemicals in plastics and processed food elevate blood pressure in children and teens

Data from nearly 3,000 children shows dietary exposure to certain plastics may play a hidden role in epidemic increases in childhood hypertension.

Plastic additives known as phthalates (pronounced THAL-ates) are odorless, colorless and just about everywhere: They turn up in flooring, plastic cups, beach balls, plastic wrap, intravenous tubing and—according to the Centers for Disease Control and Prevention—the bodies of most Americans. Once perceived as harmless, phthalates have come under increasing scrutiny. A growing collection of evidence suggests dietary exposure to phthalates (which can leech from packaging and mix with food) may cause significant metabolic and hormonal abnormalities, especially during early development.


Now, new research published this Wednesday in the Journal of Pediatrics suggests that certain types of phthalates could pose another risk to children: compromised heart health.


Drawing on data from a nationally representative survey of nearly 3,000 children and teens, researchers at NYU Langone Medical Center, in collaboration with researchers at the University of Washington and Penn State University School of Medicine, have documented for the first time a connection between dietary exposure to DEHP (di-2-ethyhexylphthalate), a common class of phthalate widely used in industrial food production, and elevated systolic blood pressure, a measure of pressure in the arteries when the heart contracts.


"Phthalates can inhibit the function of cardiac cells and cause oxidative stress that compromises the health of arteries. But no one has explored the relationship between phthalate exposure and heart health in children.

"We wanted to examine the link between phthalates and childhood blood pressure in particular given the increase in elevated blood pressure in children and the increasing evidence implicating exposure to environmental exposures in early development of disease."

lead author Leonardo Trasande, MD, MPP, associate professor of pediatrics, environmental medicine and population health, NYU Langone Medical Center.


Hypertension is clinically defined as a systolic blood-pressure reading above 140 mm Hg. It's most common in people over 50 years old, although the condition is becoming increasingly prevalent among children owing to the global obesity epidemic. Recent national surveys indicate that 14 percent of American adolescents now have pre-hypertension or hypertension.

"Obesity is driving the trend but our findings suggest that environmental factors may also be a part of the problem," says Dr. Trasande. "This is important because phthalate exposure can be controlled through regulatory and behavioral interventions."

Researchers from NYU School of Medicine, the University of Washington and Penn State University School of Medicine examined six years of data from a nationally representative survey of the U.S. population administered by the National Centers for Health Statistics of the Centers for Disease Control and Prevention. Phthalates were measured in urine samples using standard analysis techniques. Controlling for a number of potential confounders, including race, socioeconomic status, body mass index, caloric intake and activity levels, the researchers found that every three-fold increase in the level of breakdown products of DEHP in urine correlated with a roughly one-millimeter mercury increase in a child's blood pressure.

"That increment may seem very modest at an individual level, but on a population level such shifts in blood pressure can increase the number of children with elevated blood pressure substantially," says Dr. Trasande. "Our study underscores the need for policy initiatives that limit exposure to disruptive environmental chemicals, in combination with dietary and behavioral interventions geared toward protecting cardiovascular health."

This research was made possible through the generous support of KiDs of NYU Langone, an organization of parents, physicians, and friends that supports children's health services at New York University Langone Medical Center through philanthropy, community service, and advocacy.

About NYU Langone Medical Center
NYU Langone Medical Center, a world-class, patient-centered, integrated, academic medical center, is one on the nation's premier centers for excellence in clinical care, biomedical research and medical education. Located in the heart of Manhattan, NYU Langone is composed of four hospitals – Tisch Hospital, its flagship acute care facility; the Hospital for Joint Diseases, one of only five hospitals in the nation dedicated to orthopaedics and rheumatology; Hassenfeld Pediatric Center, a comprehensive pediatric hospital supporting a full array of children's health services; and Rusk Rehabilitation, ranked the best rehabilitation program in New York and one of the top ten in the country since 1989, when U.S. News & World Report introduced its annual "Best Hospitals" rankings– plus NYU School of Medicine, which since 1841 has trained thousands of physicians and scientists who have helped to shape the course of medical history. The medical center's tri-fold mission to serve, teach and discover is achieved 365 days a year through the seamless integration of a culture devoted to excellence in patient care, education and research.
