Book excerpt: With a few notable exceptions, mammalian preimplantation embryos grown in vitro are likely to exhibit sub-optimal or retarded development. This may be manifested in different ways, depending on the species and on the stage(s) of embryonic development that are being examined. For example, bovine embryos often experience difficulty in cleaving under in vitro conditions, and usually cease development at about the 8-cell stage (Wright and Bondioli, 1981). The block to development is stage-dependent; embryos cultured for 24 hr from the I-cell stage are much more capable of developing into viable blastocysts after transfer to oviducts than embryos cultured for 24 hr from the 4-cell stage prior to transfer (Eyestone et oZ. , 1985). Similar problems with in vitro embryo development are encountered in other species. Pig embryos can be grown up to the 4-cell stage in vitro but usually no further (Davis and Day, 1978). In the golden hamster, in the rat and in many outbred strains of mice, development of zygotes in vitro is blocked at the 2-cell stage (Yanagimachi and Chang, 1964; Whittingham, 1975). Even with some inbred mouse strains, embryo development is reduced if very early cleavage stages are used as the starting point for in vitro culture (Spielmann et oZ. , 1980). A common finding is that embryos grown in vitro have reduced cell counts (Harlow and Quinn, 1982; Kane, 1985) and their viability is reduced (Bowman and McLaren, 1970; Papaioannou and Ebert, 1986) compared to equivalent developmental stages recovered from mated animals.

Download or read book Cell Signaling During Mammalian Early Embryo Development written by Henry J. Leese and published by Springer. This book was released on 2015-05-08 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book considers signaling events from the zygote embryo through to the blastocyst with relevant data from embryonic stem (ES) cells, including dialogue with the extracellular environment and with the maternal tract during the implantation process. Application of the knowledge described to improve the success of human and animal assisted conception is considered where appropriate, but the focus is largely on fundamental rather than applied cell/molecular biology, as this is the area that has historically been neglected. While the general features of metabolism during preimplantation development are well established, especially in terms of nutrient requirements, uptake and fate, remarkably little is known about early embryo signaling events, intracellular or intercellular, between individual embryos in vitro or with the female reproductive tract in vivo. This contrasts with the wealth of information on cell signaling in somatic cells and tissues, as a glance at any textbook of biochemistry illustrates. This lack of information is such that our understanding of the molecular cell biology of early embryos -- a prerequisite to defining the mechanisms which regulate development at this critical stage of the life cycle -- is seriously incomplete. This volume is the first to address this issue by describing the current state of knowledge on cell signaling during mammalian early embryo development and highlighting priority areas for research.

This book was released on 2012-12-06 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the Proceedings of the Serono Symposium on Pre implantation Embryo Development, held in Newton, Massachusetts, in 1991. The idea for the symposium grew out of the 1989 Serono Symposium on Fertilization in Mammals* at which preimplantation development was the predominant suggestion for a follow-up topic. This was indeed a timely subject in view of the recent resurgence of interest in this funda mental phase of embryogenesis and its relevance to basic research and applied fertility studies in humans, food-producing animals, and endangered species. The symposium brought together speakers from a broad range of disciplines in order to focus on key regulatory mechanisms in embryo development, using a wide variety of animal models, and on representative topics in human preimplantation embryogenesis. The culmination of preimplantation development is a blastocyst con taining the first differentiated embryonic tissues and capable of initiating and sustaining pregnancy. The central objective of the symposium was to throw light on the regulation of cellular and molecular events underlying blastocyst formation. It was particularly appropriate that the date of the symposium marked the 20th anniversary of the publication of the classic volume Biology of the Blastocyst, the proceedings of an international workshop held in 1970. This book, which summarized most of the information then available on this topic in mammals, was edited by the pioneer in blastocyst research, Dr. Richard B1andau, who was the guest speaker at the symposium.
Download or read book Assessment of Mammalian Embryo Quality written by A. van Soom and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thanks to enormous scientific efforts of the last decades, in vitro fertilization (IVF) and in vitro production (IVP) have now been introduced successfully in the practice of human infertility treatment and cattle breeding programs. This comprehensive book allows us to bridge the knowledge from both biomedical and veterinary fields of research. For the first time, studies concerning the human embryo as well as embryos from domestic species are brought together. The central theme of the book is "the assessment of mammalian embryo quality". In 15 chapters, written by well-known scientists, different aspects of the assessment of mammalian embryo quality are summarized. Non-invasive and invasive techniques to evaluate embryo quality are separated in two parts. In addition the book is provided with appendices on practical aspects and, thus, the book should be present in each laboratory for IVF and IVP.

This book was released on 2020-08-31 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of the recent advances in embryo modeling techniques, and at the request of the Office of Science Policy in the Office of the Director at the National Institutes of Health, the National Academies of Sciences, Engineering, hosted a 1-day public workshop that would explore the state of the science of mammalian embryo model systems. The workshop, which took place on January 17, 2020, featured a combination of presentations, panels, and general discussions, during which panelists and participants offered a broad range of perspectives. Participants considered whether embryo model systems - especially those that use nonhuman primate cells - can be used to predict the function of systems made with human cells. Presentations provided an overview of the current state of the science of in vitro development of human trophoblast. This publication summarizes the presentation and discussion of the workshop.

Download or read book ART and the Human Blastocyst written by David K. Gardner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of human artificial reproductive technology (ART) is continually advancing and has witnessed significant changes since the inception of Louise Brown in 1978. Though Louise Brown herself was conceived after the trans fer of a blastocyst, there remain significant confusion and debate regarding the stage at which the human embryo conceived in the laboratory should be replaced in the mother. Developments in culture media formulations, leading to the introduction of sequential media, have brought the role of the blasto cyst in human ART back into the spotlight. It was due to this resurgence of interest in the niche of extended culture in human infertility treatment that the symposium on "ART and the Human Blastocyst" was held. of this meeting within this volume bring to the forefront The proceedings the main issues raised with the transfer of embryos at the blastocyst stage. It is evident from the chapters that follow that ART needs to be perceived as a continuum of procedures, each one dependent on the preceding one, and all equally as important as each other. That is to say, the development of a com petent embryo is ultimately dependent on the quality of the gametes from which it was derived. With regard to the oocyte, this then places the emphasis on the physician to use a stimulation protocol that both produces quality oocytes and does not impair endometrial function. Maintenance of gamete and embryo quality is the laboratory's role.
Download or read book Manipulation of Mammalian Development written by Ralph B.L. Gwatkin and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developmental biology has been transformed recently by discoveries in the fields of molecular biology, cell biology, and immunology. New ways of manip ulating mammalian development are uncovering control mechanisms and ena bling us to apply them in solving practical problems in animal production and human health. This book outlines some of these new manipulations and how they have contributed to the present state of developmental biology. Chapter 1 describes gene transfer by micro injection of cloned recombinant DNA into zygotes. Although the factors that affect transformation frequencies and integration sites are still unknown, such techniques offer a number of exciting prospects. Research models for human disease coula be artificially created and desirable characteristics in agricultural animals could be - hanced. . The theme of cell-to-cell transfer is continued in Chapters 2 and 3. Chapter 2 describes pronuclear transplantation by Sendai virus-induced fusion of the karyoplast with the enucleated embryo. Using this procedure, it has been dem onstrated that both male and female genomes are essential for normal develop ment, although the reason for this is not yet understood. Chapter 3 describes studies on the fusion of whole oocytes. .

Download or read book Placentation in Mammals written by Rodney D. Geisert and published by Springer Nature. This book was released on 2021-10-25 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present volume of the book series Advances in Anatomy, Embryology and Cell Biology brings together current reviews from leading experts to address the diversity of placentation by which species establish and maintain pregnancy. Development of viviparity and placentation in rodents, dogs, pigs, cattle, horses, marsupials, primates and elephants are discussed. The development of viviparity in mammals, including some invertebrate species, required the adaptation of the placenta to serve as a functional conduit for interplay between the semiallograftic fetus with the maternal uterus. Although the ‘placenta’ protects the fetus from maternal immune rejection and provides oxygen and nutrient flow to support it to term across all the species, structural differentiation of this fetal-maternal interface can vary from simple to very complex. E.C. Amoroso contributed greatly to our early understanding and knowledge of placentation across a great variety of species. His work on placentation provides numerous illustrations and histological sections which are used for teaching and stimulating research today. With this book, we want to pay tribute to his lifetime contributions to the field by reviewing our current understanding of the development of viviparity and placentation in different species. The book is written for researchers, physicians and medical students working in the field of reproductive science or with an interest in placentation and viviparity.
Download or read book Manual of Embryo Culture in Human Assisted Reproduction written by Kersti Lundin and published by Cambridge University Press. This book was released on 2021-05-06 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whilst assisted reproduction techniques (ART) have become increasingly successful and largely standardized, there is still only a partial understanding of what constitutes a 'true' embryo environment. Replicating the varying physiological conditions of the in-vivo environment that the embryo travels through in the in-vitro culture is still a major challenge in ART. This practical volume details how to organize and operate an IVF laboratory in order to mimic these conditions for successful embryo culture. Environments and equipment that are essential for running safe and efficient facilities such as maintaining good air quality and hygiene protocols, and utilizing an effective layout are covered in detail. Other chapters discuss the different consumables needed, optimal handling techniques and parameter monitoring systems, as well as recent advances in the area including artificial intelligence and automation. This is an indispensable guide to understanding the background science of culturing embryos, crucial to successful outcomes in ART.
