Despite its inherent controversy, the exploration of the human embryo can unlock many of the answers to our deepest biological questions. In Human Embryogenesis: Methods and Protocols, internationally recognized researchers contribute detailed methods to analyze various aspects of the embryogenesis process. While comprehensively covering subjects such as the molecular mechanisms of embryonic development, in vitro fertilization, cloning, and the laws and ethical considerations of working with embryos, the volume also addresses critical features of fetal and placental development as well as of uterine biology. Written in the highly successful Methods in Molecular Biology¿ series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and state-of-the-art, Human Embryogenesis: Methods and Protocols provides a firm foundation for the successful analysis of the embryogenesis process and an easily accessible description of the limitations and advantages of the techniques proposed, certain to aid all those who wish to further unravel the mysteries of human embryogenesis.
