In the face of extraordinary advances in the prevention, diagnosis, and treatment of
human diseases, devastating illnesses such as heart disease, diabetes, cancer, and diseases
of the nervous system, such as Parkinson’s Disease and Alzheimer’s Disease, continue to
deprive people of health, independence, and well-being. Research in human develop-
mental biology has led to the discovery of human stem cells (precursor cells that can give
rise to multiple tissue types), including embryonic stem (ES) cells, embryonic germ (EG)
cells, and adult stem cells. Recently, techniques have been developed for the in vitro
culture of stem cells, providing unprecedented opportunities for studying and under-
standing human embryology. As a result, scientists can now carry out experiments aimed
at determining the mechanisms underlying the conversion of a single, undifferentiated
cell, the fertilized egg, into the different cells comprising the organs and tissues of the
human body. Although it is impossible to predict the outcomes, scientists and the public
will gain immense new knowledge in the biology of human development that will likely
hold remarkable potential for therapies and cures.
