Research in this area promises to lead to new therapies for cancer, heart disease, diabetes, and a wide variety of other diseases. This two-volume reference integrates this exciting area of biology, combining the prerequisites for a general understanding of adult and embryonic stem cells, the tools, methods, and experimental protocols needed to study and characterize stem cells and progenitor populations, as well as a presentation by the worlds experts of what is currently known about each specific organ system. The editors of the Handbook of Stem Cells include: Robert Lanza, Helen Blau, John Gearhart, Brigid Hogan, Douglas Melton, Malcolm Moore, Roger Pedersen, E. Donnall Thomas, James Thomson, Catherine Verfaillie, Irving Weissman, and Michael West. The Editorial Board includes: W.
