Although much is known with respect to blood cell formation and function, many new concepts in the areas of the regulation of hematopoietic stem cell commitment and the subsequent survival, proliferation, and differentiation of progenitors have been elucidated in the last five years. Our understanding of the microenvironment where stem cells reside and commit to distinct blood types (the niche) has grown significantly in recent years. Furthermore, blood cells have been used as the key model system to study microRNA function and the role of microRNAs in the transformation of normal cells into cancer cells. The current volume Molecular Basis of Hematopoiesis, edited by Amittha Wickrema & Barbara Kee, provides the most recent developments in the area in addition to a chapter on the utilization of basic science knowledge for the treatment of blood diseases. Each chapter in this book has been written and edited by faculty in major academic and research institutions around the world, who are pushing the frontiers of research in this important area.

Thanks to animal models, our knowledge of biology and medicine has increased enormously over the past decades, leading to significant breakthroughs that have had a direct impact on the prevention, management and treatment of a wide array of diseases.This book presents a comprehensive reference that reflects the latest scientific research being done in a variety of medical and biological fields utilizing animal models. Chapters on Drosophila, rat, pig, rabbit, and other animal models reflect frontier research in neurology, psychiatry, cardiology, musculoskeletal disorders, reproduction, chronic diseases, epidemiology, and pain and inflammation management. Animal Models in Medicine and Biology offers scientists, clinicians, researchers and students invaluable insights into a wide range of issues at the forefront of medical and biological progress.
This book brings together genetics, reproductive biology and medicine for an integrative view of the emerging specialism of reproductive genetics.
Advances in cytogenetics continue to crop up in wonderful ways, and we know exponentially more about chromosomes now than mere decades ago. Likewise, the necessary skills in offering genetic counseling continue to evolve. This new edition of Chromosome Abnormalities in Genetic Counseling offers a practical, up-to-date guide for the genetic counselor to marshal cytogenetic data and analysis clearly and effectively to families.
The mouse is a perfect model organism to study mammalian, and thus indirectly also human, embryology. Most scientific achievements that have had an important impact on the understanding of basic mechanisms governing embryo development in humans, originated from mouse embryology. Stem cell research, which now offers the promise of regenerative medicine, began with the isolation and culture of mouse embryonic stem cells by Martin Evans (who received the Nobel Prize in medicine in 2007 for this achievement) and Matthew Kaufman. This book provides an overview of mouse development, spanning from oocytes before fertilization to the state-of-the-art description of embryonic and adult stem cells. The chapters, written by the leading specialists in the field, deal with the most recent discoveries in this extremely fast-developing area of research.
This book presents the latest advances concerning the regulation of chromosome segregation during cell division by means of centromeres and kinetochores. The authors cover both state-of-the-art techniques and a range of species and model systems, shedding new light on the molecular mechanisms controlling the transmission of genetic material between cell divisions and from parent to offspring. The chapters cover five major areas related to the current study of centromeres and kinetochores: 1) their genetic and epigenetic features, 2) key breakthroughs at the molecular, proteomic, imaging and biochemical level, 3) the constitutive centromere proteins, 4) the role of centromere proteins in the physical process of chromosome segregation and its careful orchestration through elaborate regulation, and 5) intersections with reproductive biology, human health and disease, as well as chromosome evolution. The book offers an informative and provocative guide for newcomers as well as those already acquainted with the field.
