In introducing this 16-chapter collection, Turksen (Ottawa Health Research Institute, Canada) notes that while these global scientists do not directly enter the moral/political debate raging over stem cells for therapeutic use, they do contribute to understanding their potential and regulatory issues. The first chapter explains the plasticity property that accounts for these cells' uniqueness for treating diseases, and raises concerns that opportunities may be missed by focusing on adult cells rather than the more controversial embryonic ones. Other contributors discuss stem cell biology, specific types of cells, and their culture. The illustrations include color plates. Annotation ©2004 Book News, Inc., Portland, OR
