Stem cells have the remarkable potential and property to develop into many different cell types in the body during early life and growth. Apart from that in various tissues, stem cells serve a purpose of internal repair system in some degree, dividing in essence without limit to replenish other cells as long as the person or animal is possessing life. When a stem cell divides, each new cell has the existing possibility of either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, a brain cell etc. Stem cells provide new potentials for treating diseases such as Parkinson''s disease, diabetes, and heart diseases. KEY FEATURES: • Theoretical approaches, large number of examples and references. • Real application scenarios, such as stem cell research project, which require the use of a whole set of drug design tools. • Illustrations help readers understand the research methodology easily. • Lists of Web resources of important research centers, institutes, and other sources of information.
