Book Description
It is not okay to call something a miracle without even trying to understand it. This is human developmental biology (human embryology, in terms of cells and molecules) for everyone curious enough to see it through, from the perspective of the business of becoming human as individuals and as species; making new humans; how it happens (cells do it, ALL of it); and common variations of the process. It cannot be made quite simple and be kept quite true, but we will move as far toward simple as we can without losing touch with sound evidence. Variations from the normal version of the process, particularly malformations and twinning and chimerism, figure prominently in the story because there is no better way to learn about the usual than to study the unusual and see what differences in the endings these observable differences at the beginnings can make. In this book, when technical terminology is the only way, or the best way, to say what needs to be said, it is defined and explained making the words a worthwhile part of what is here to be learned. This book defines its own new field. We cannot claim to understand how anything human] works as human], with no effort at understanding the emergence of its form and functions. Old and new unanswered questions are waiting to be dug out from under old unquestioned answers about how becoming human unfolds. We will also address some popular and weighty, but deeply empty assertions about the circumstances and mechanisms of our beginnings and our ceaseless becoming. We will find fundamental questions from the humanities' unanswerable except from biology. Human developmental biology is a foundational discipline within the humanities.

Book Description
This book, which was originally published in 1986, introduces the reader to the main steps in the analysis of chimeras, explains their structural and developmental basis, and the ways of classifying and manipulating them. The twelve chapters separate types of chimeras according to their origin - by grafting or polyploidy; their structure - sectorial or periclinal; or according to the varied parts of the plant most affected - tubers, leaves, flowers or fruit. Throughout the book care is taken to distinguish between the activity of the growing-point in determining chimera structure, and the role of gene expression in determining appearance. Examples of the experimental uses of chimeras are given and of the valuable role they can play in studying fundamental questions of anatomical development; the disadvantages of chimeras in mutation breeding are discussed too.

Book Description
This volume addresses challenging new questions surrounding stem cell-based chimera research. This book is organized into three parts: Part One provides readers with a summary of different human donor cell types. The chapters in this section discuss ways to evaluate new types of pluripotent stem cells; the derivation of naïve and primed pluripotent stem cells from mouse preimplantation embryos; and the ethical and regulatory complexities of informed consent for the procurement of somatic cells. Part Two discusses methods for generating chimeras. The chapters here look at chick models and human-chick organizer grafts; generating human-pig interspecies chimeras; and techniques for transplanting mouse neural stem cells into a mouse disease model for stroke. Part Three concludes the book with a look at ongoing ethical controversies and new scientific directions. Chapters in this part cover the ethics of crossing the xenobarrier; animal welfare; experimentation with spermatogonial stem cells; and cautious approaches to human-monkey chimera studies to further understand complex human brain disorders. 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 tips on troubleshooting and avoiding known pitfalls. Cutting-edge and thorough, Chimera Research: Methods and Protocols is a valuable resource for scientists interesting in using chimeras as a research tool while also taking into consideration their complex ethical scopes.

Book Description
This Dictionary presents a broad range of topics relevant in present-day global bioethics. With more than 500 entries, this dictionary covers organizations working in the field of global bioethics, international documents concerning bioethics, personalities that have played a role in the development of global bioethics, as well as specific topics in the field.The book is not only useful for students and professionals in global health activities, but can also serve as a basic tool that explains relevant ethical notions and terms. The dictionary furthers the ideals of cosmopolitanism: solidarity, equality, respect for difference and concern with what human beings- and specifically patients - have in common, regardless of their backgrounds, hometowns, religions, gender, etc. Global problems such as pandemic diseases, disasters, lack of care and medication, homelessness and displacement call for global responses.This book demonstrates that a moral vision of global health is necessary and it helps to quickly understand the basic ideas of global bioethics.

Book Description
Scientists and philosophers have long struggled to answer the questions of when human life begins and when human life has inherent value. The phenomenon of identical (monozygotic) twinning presents a significant challenge to the view that human life and human personhood begin at conception. The fact that a single embryo can split to generate two (or more) genetically identical embryos seems to defy the notion that prior to splitting an embryo can be a single human individual. In Untangling Twinning, Maureen Condic looks at the questions raised by human twinning based on a unique synthesis of molecular developmental biology and Aristotelian philosophy. She begins with a brief historical analysis of the current scientific perspective on the embryo and proceeds to address the major philosophic and scientific concerns regarding human twinning and embryo fusion: Is the embryo one human or two (or even more)? Does the original embryo die, and if not, which of the twins is the original? Who are the parents of the twins? What do twins, chimeras, cloning, and asexual reproduction in humans mean? And what does the science of human embryology say about human ensoulment, human individuality, and human value? Condic's original approach makes a unique contribution to the discussion of human value and human individuality, and offers a clear, evidence-based resolution to questions raised by human twinning. The book is written for students and scholars of bioethics, scientists, theologians, and attorneys who are involved in questions surrounding the human embryo.
