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!

TET1 Crucial to Fetal Development and Cancer
TET1 ensures normal fetal development and is crucial when certain genes need to turn on or off during cell division.

Aging Eggs Key to Miscarriage and Birth Defects
By the time a woman is in her 40s, about half her eggs are probably chromosomally abnormal; for women in their 20s, it's probably about 10 percent.

Human umbilical cord blood stem cells, or uMSCs for mensenchymal stem cells, benefit in treating lupus nephritis (LN) - a kidney disorder common in lupus erythematosus (SLE).

SLE is an autoimmune disease characterized by many clinical conditions, including lupus nephritis (LN), a leading cause of death for patients with SLE.

Study results are published in the current issue of Cell Transplantation (20:2).

According to Dr. Oscar K. Lee of the National Yang-Ming University School of Medicine, mensenchymal stem cells can alleviate unnecessary immune responses by inhibiting inflammation and the function of mature and immature immune system T cells. The study transplanted umbilical cord blood-derived stem cells into mice modeled with systemic immune diseases closely resembling SLE in humans.

"We found that uMSC transplantation markedly delayed the deterioration of renal function, reduced certain antibody levels, alleviated changes in renal pathology and the development of proteinuria - the presence of excess protein serum in the urine and a sign of renal damage," said Dr. Lee.

The increased survival rate for mice treated at two months of age compared with mice treated at six months of age, led to the conclusion that early mensenchymal stem cell transplantation is the more effective treatment. Researchers also believe that the use of allogenic - or other donated - rather than autologous (self-donated) mensenchymal stem cells for SLE treatment, is more effective. A conclusion that makes sense with an autoimmune disorder.

"The therapeutic effects demonstrated in this pre-clinical study support further exploration of the possibility of using uMSCs from mismatched donors in LN treatment," concluded Dr. Lee.

"The ability of uMSCs to reduce inflammation means that they are likely to be of use in the treatment of autoimmune disorders and this study supports that reasoning and, in this case, also advocates the use of non-self cells," Dr. David Eve, associate editor of "Cell Transplantation" and an instructor at the University of South Florida Center of Excellence for Aging and Brain Repair.
