Regarded as the Bible of mammalian embryo manipulation techniques since the 1986 publication of the first edition of Manipulating the Mouse Embryo: A Laboratory Manual, the third edition of this essential laboratory resource has now been completely reorganized, rewritten, and updated by a new cast of authors. The result is a compilation of new, cutting-edge protocols that include embryonic stem cell production and genetic manipulation, mouse chimeras, mouse cloning, assisted reproduction strategies (including intracytoplasmic sperm injection and in vitro fertilization), whole embryo culture systems, electroporation, embryo and gamete cryopreservation and rederivation, and gene expression, as well as more extensive background information on the use of these techniques. The gold standard techniques for applying recombinant DNA technology to investigations of mammalian embryonic development included in the first two editions of this book are also updated and recast, as is the summary of the current state of understanding of mouse development at the molecular level. This book is the premier authoritative and comprehensive source of technical and theoretical guidance for mouse developmental biologists and geneticists and is an essential resource for newcomers to these fields. Key features of the third edition: New authors are leading authorities in mouse development and genetics, as were authors of prior editions. All new illustration and new design: All illustrations have been redrawn; extensive use of new illustrations and photographs of techniques and results; a new, contemporary design presents techniques more clearly. New explanatory text: More background information for techniques is presented as well as more extensive troubleshooting information. New, functional organization and techniques.
