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!

New research out of McGill University's Goodman Cancer Research Centre provides compelling new evidence that a gene known as 14-3-3œ plays a critical role in stopping breast cancer initiation and progression.

The study, led by the Dept. of Biochemistry's William J. Muller, will be published online today in the journal Cancer Discovery.

The discovery of this new target points to novel therapies that eventually could slow or stop breast cancer progression. Muller also says that this gene is likely a major player in a number of other types of cancer.

Based on past clinical observations revealing that the expression of gene 14-3-3œ is silenced in a large percentage of breast cancers, researchers had long suspected that it played a role in stopping cancer cells from dividing. The McGill team wanted to confirm whether this was the case. Using a transgenic mouse model that expresses ErbB2, an oncogene associated with aggressive breast cancers, they inactivated the 14-3-3œ gene in the mammary gland.

"We found that the loss of this expression did, in fact, result in a dramatic acceleration of tumour onset," explained Muller who is also affiliated with the Research Institute of the McGill University Health Centre (RI MUHC). "The two genes, 14-3-3œ and ErbB2, co-operate, with 14-3-3œ being the brakes. If you lose the brakes, ErbB2 can induce the cells to divide indefinitely. Furthermore, not only is the ability of these cells to divide enhanced but they become extraordinarily metastatic. They can invade distant sites."

"We are pleased that our funding has led to a better understanding of molecular mechanisms of breast cancer development, which ultimately will lead to improved interventions for breast cancer patients " said Dr. Morag Park, the Scientific Director of the CIHR, Institute of Cancer.
