Book Synopsis Oocyte Growth and Maturation by : T.A. Dettlaff

Download or read book Oocyte Growth and Maturation written by T.A. Dettlaff. This book was released on 2012-12-06. Available in PDF, EPUB and Kindle. Book excerpt: Studies of oogenesis occupy an important place in current in vestigations in developmental biology. Today no one has any doubt whatsoever that oogenesis is not just the prelude to development, but is development itself, and a very essential part of it. These words of an eminent Soviet scientist, B. L. As taurov , taken by T. B. Aizenshtadt as an epigraph to her chapter in this book, make a good epigraph for the entire book. It is now clear that during oogenesis not only vast reserves of ribosomes and mitochondria, of yolk, carbohydrates, and lipids, and of enzymes for protein and nucleic acid synthesis and for carbohydrate and fat metabolism (which ensures the energy supply and metabolism of the oocyte and the developing embryo) are formed, but also long-lived mRNA and proteins are synthesized, which determine both the completion of oocyte maturation and the initial stages of embryonic development. In the last 15-20 years, the use of molecular biology methods, electron microscopy, autoradiography, and microsurgical methods of experimental embryology in studying the pre-embryonic development of animals has greatly increased our knowledge of oogenesis. This has led to the need to systematize the data obtained, to reinter pret old ideas, and to review the results obtained by new research trends which have emerged in the last few years and which are of general biological interest. Such a task was undertaken in the book Sovremennye Problemy Oogeneza (Current Problems of Oogenesis), published in 1977 (in Russian).

Book Synopsis Development of In Vitro Maturation for Human Oocytes by : Ri-Cheng Chian

Download or read book Development of In Vitro Maturation for Human Oocytes written by Ri-Cheng Chian. This book was released on 2017-05-10. Available in PDF, EPUB and Kindle. Book excerpt: An ideal reference for infertility specialists and reproductive endocrinologists alike, this comprehensive text discusses current natural and mild approaches to in vitro fertilization (IVF) and the development of in vitro maturation (IVM) as a clinical treatment. It is divided thematically into four sections. Part I presents the basic science of ovarian endocrinology and the mechanism of oocyte maturation, including follicular development and the importance of mitochondrial changes. The differences between natural cycle IVF and stimulated IVF are presented in part II, including the standard ovarian stimulation protocols and their outcomes and the etiology, prevention and management of ovarian hyperstimulation syndrome (OHSS). Minimal and mild stimulation for IVF is discussed in part III, including mild stimulation protocols for oncofertility patients and the new minimally invasive INVO procedure. In vitro maturation as a clinical treatment is the subject of part IV, discussing the methodology of immature oocyte retrieval as well as other laboratory aspects and congenital and obstetrical outcomes of babies born from IVM. Combining expertise from thought leaders around the world, Development of In Vitro Maturation for Human Oocytes will be a go-to resource for infertility researchers and practitioners and reproductive endocrinologists working with infertile couples looking for safer and more cost-effective options for treatment.

Download or read book Molecular Mechanisms of Cell Differentiation in Gonad Development written by Rafal P. Piprek. This book was released on 2016-06-14. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the current state of knowledge on the origin and differentiation of cell lines involved in the development of the vertebrate male and female gonads with particular emphasis on the mouse. It also discusses the processes leading to the testis- and ovary-specific structures and functions. The individual chapters review the origin and differentiation of the somatic cells of the genital ridges; the formation and migration of primordial germ cells in mouse and man; the gonadal supporting cell lineage and mammalian sex determination; differentiation of Sertoli and granulosa cells; mesonephric cell migration into the gonads and vascularization; origin and differentiation of androgen-producing cells in the gonads; germ cell commitment to the oogenic versus spermatogenic pathway and the role of retinoic acid; ovarian folliculogenesis; control of oocyte growth and development by intercellular communication within the follicular niche; biology of the Sertoli cell in the fetal, pubertal and adult mammalian testis; mechanisms regulating spermatogonial differentiation; stem cells in mammalian gonads; the role of microRNAs in cell differentiation during gonad development; human sex development and its disorders; as well as methods for the study of gonadal development.

Book Synopsis The Fish Oocyte by : Patrick J. Babin

Download or read book The Fish Oocyte written by Patrick J. Babin. This book was released on 2007-08-20. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the growing needs in deciphering the biological processes associated with fish reproduction, in view of the growth of aquaculture and the dwindling natural stocks of commercially important fish. It presents a comprehensive overview on egg production in fish, from the standpoint of the oocyte. With this view in mind, the book includes chapters on oocyte development (oogenesis), hormonal regulation and hormone receptors, formation of the egg envelopes, growth, accumulation of nutrients and maternal transcripts, maturation, hydration, ovulation and fertilization. A special emphasis is placed on using state-of-the-art tools including electron microscopy for discerning the ultra-structure of the follicle and genomic/proteomic tools to fully understand biological basis of fish reproduction. Studies on promoting oocyte maturation, ovulation and spawning in farmed fish and preservation of fish oocytes at low temperatures are also included. The book will appeal to University lecturers, students, research scientists and those associated with culture of fish in freshwater or marine aquaculture.
