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!

Formation of liver, pancreas and esophagus from the endoderm layer of fetal cells,
begins about 30 days post ovulation. An antibody developed by Martin Pera's group
is able to identify progenitor organ stem cells in a diseased state in order to assist
in the treatment of cancers of these organs, with a specific interest in pancreatic cancer.

Stem Cell Research Aids Understanding of Cancer

An international team of scientists have discovered a novel marker that plays an important role in our understanding of how cancer develops in the liver, pancreas and oesophagus

The study, led by renowned stem cell scientist Professor Martin Pera and published in the journal Stem Cell, adds to our understanding of the role of stem and next stage progenitor cells in tissue regeneration and in the diagnosis and treatment of cancer.

While stem cells are known to reside in organs such as the liver and pancreas, they are difficult to isolate. The new findings show that an antibody developed by the team can be used to capture the stem cells.

Professor Pera, program leader for Stem Cells Australia and Chair of Stem Cell Sciences at the University of Melbourne, said the antibody was able to detect progenitor cells in disease states such as cirrhosis of the liver, and in cancers such as pancreatic adenocarcinoma and oesophageal carcinoma.


“By being able to identify these cells,
we hope to be able to learn more about their role
in tissue regeneration and in cancer
especially in the diagnosis and treatment
of pancreatic cancer.”

“Cancers of the liver, pancreas and oesophagus
are often very difficult to detect and challenging to treat.”

“This funding will support us to develop more antibodies that can be used to assist in the identification and prospective isolation of stem and progenitor cells in these tissues and lead to the development of novel diagnostic and therapeutic reagents,” said Professor Pera.

The large collaboration of scientists from around the world working on this study evolved over many years with research undertaken in Professor Pera’s laboratories at the then Australian Stem Cell Centre and at the University of Southern California

Professor Pera and one of the co-authors on the paper, Dr Kouichi Hasegawa, were recently awarded an Australia-India Strategic Research Fund grant to continue their search for novel markers for liver, pancreatic and gut stem cells. Dr Hasegawa, who recently undertook a three month sabbatical at Stem Cells Australia, holds positions at Kyoto University’s Institute for Integrated Cell-Materials Sciences and at the Institute for Stem Cell Biology and Regenerative Medicine at the National Centre for Biological Sciences in Bangalore, India.
