New discoveries in the field of stem cell research have frequently appeared in the news and in scientific literature. 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. French Anderson, Peter Andrews, Anthony Atala, Jose Cibelli, Giulio Cossu, Robert Edwards, Martin Evans, Elaine Fuchs, Margaret Fuller, Fred Gage, Richard Gardner, Margaret Goodell, Ronald Green, William Haseltine, Joseph Itskovitz-Eldor, Rudolf Jaenisch, Ihor Lemischka, Dame Anne McLaren, Richard Mulligan, Stuart Orkin, Martin Pera, Benjamin Reubinoff, Janet Rossant, Hans Scholer, Austin Smith, Evan Snyder, Davor Solter, Alan Trounson, and Leonard Zon. This comprehensive set should be a much-needed addition to the library of students and researchers alike.
