This detailed volume explores a variety of techniques used to study lineage commitment in stem cells. Further elucidation of the process that stem cells undergo on their way to becoming more specified cell types is vital for a more complete understanding of cell biology and overall physiology. 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, as well as tips on troubleshooting and avoiding known pitfalls.
