Stem Cells & Cloning provides an introduction to two of the most controversial biological technologies in the world today. Author David A. Prentice defines stem cells, their sources, and their potential applications in the area of degenerative disease research. Embryonic and adult stem cells are addressed along with the scientific, political, and ethical ramifications of their use in modern science. Dr. Prentice considers many of these same bioethical questions in the second half of this informative booklet when the rapid developments in the area of mammalian cloning technology are considered.
