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!

Group child care reduces emotional problems in children of depressed moms

Fewer social withdrawal symptoms were observed than when children were in maternal care.

Child care is linked to fewer emotional problems and symptoms of social withdrawal among children exposed to maternal depression, according to a new study of nearly 2000 children conducted by researchers in Montreal, Canada, at the Sainte-Justine University Hospital Research Center, Université du Québec à Montréal (UQAM), and University of Montreal.

The study "Maternal Depressive Symptoms and Children's Emotional Problems Can Early Child Care Help Children of Depressed Mothers?" was published in the prestigious journal JAMA Psychiatry on June 19, 2013.


"We found that children exposed to maternal depression during the preschool years were nearly two times more likely to develop emotional problems and separation anxiety symptoms. However, regular child care attendance of at least 8 hours per week was linked to a more positive outcome for these children, such as reduced chances of developing emotional problems and symptoms of social withdrawal."

Dr. Catherine Herba, researcher, lead author of the study, Sainte-Justine University Hospital Research Center. Dr. Herba is also an assistant professor in the Department of Psychology at UQAM, and with the Department of Psychiatry at the University of Montreal.


Entering child care at a younger age (i.e. before 17 months of age) or later in the preschool period was associated with similarly beneficial effects. Most importantly, it was not the intensity of exposure that was linked to lower levels of emotional problems, but rather the type of child care arrangement that proved most crucial, the key being regulated group-based child care – either in a family environment or a daycare center.


Child care arrangements with family members or babysitters, usually individual care within the child's home, were not associated with reduced risk of developing emotional problems in these children.


"Further work needs to be done for us to understand the exact mechanisms responsible for this effect," Dr. Herba added. "However results clearly point toward the benefits of regulated group-based child care for children exposed to symptoms of maternal depression during their preschool years. This could be due to the more structured setting; care provided by trained professionals; the child being out of their home; or exposure to other children of a similar age."

Dr. Sylvana Côté, a co-author of the study, also noted that "it is important that we support young families, particularly those at risk, by providing access to quality child care services." Dr. Côté is also a researcher at Sainte-Justine University Hospital Research Center and associate professor in the Department of Social and Preventive Medicine at the University of Montreal.

About the study
Findings were based on the Quebec longitudinal study of child development. The study was supported by the Québec Government's Ministère de la Santé et des Services sociaux, the Fonds de recherche du Québec - Santé, the Fonds de recherche du Québec - Société et culture, Canada's Social Sciences and Humanities Research Council, the Canadian Institutes of Health Research, the Sainte-Justine University Hospital Research Center, and the University of Montreal. Researchers from the Université du Québec à Montréal, the Université de Montreal, Université Laval, and University College Dublin contributed to this study. Data was collected and managed by the Institut de la statistique du Québec.
