This detailed volume collects updates on the technical advances in hematopoietic stem cell research and incorporates new techniques focused on the molecular/genetic, cellular, and whole organism levels. Exploring methods that apply stress to hematopoiesis, the book also contains chapters focused on better understanding the role of hematopoietic niches and their cellular components, as well as in vivo models that test and quantitate stem cell function and are key to further development of therapeutic applications. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step and readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
