Drawing on the dramatically increasing research on embryonic stem (ES) cell biology and differentiation, Kursad Turksen has completely updated and expanded his highly acclaimed first edition of Embryonic Stem Cells: Methods and Protocols into two volumes. The second volume, Embryonic Stem Cell Protocols: Differentiation Models, Second Edition, covers state-of-the-art methods for deriving many types of differentiating cells from ES cells. A companion first volume, Embryonic Stem Cell Protocols: Isolation and Characterization, Second Edition, focuses on ES cells recently isolated from different nonhuman species, to provide a diverse collection of readily reproducible cellular and molecular protocols for the isolation, maintenance, and characterization of embryonic stem cells. The protocols follow the successful Methods in Molecular Biology series format, each offering step-by-step laboratory instructions.
