Platelets And Megakaryocytes

12 The average human body has in the order of 10 circulating platelets. They are crucial for hemostasis, and yet excessive platelet activation is a major cause of m- bidity and mortality in western societies. It is therefore not surprising that platelets have become one of the most extensively investigated biological cell types. We are, however, far from understanding precisely how platelets become activated under physiological and pathophysiological conditions. In addition, there are large gaps in our knowledge of platelet production from their giant precursor cell, the megakar- cyte. Understanding megakaryocyte biology will be crucial for the development of platelet gene targeting. The aim of Platelets and Megakaryocytes is therefore to bring together established and recently developed techniques to provide a comprehensive guide to the study of both the platelet and the megakaryocyte. It consists of five s- tions split between two volumes. The more functional assays appear in Volume 1, whereas Volume 2 includes signaling techniques, postgenomic methods, and a n- ber of key perspectives chapters. Part I of Volume 1, Platelets and Megakaryocytes: Functional Assays, describes many well established approaches to the study of platelet function, including aggregometry, secretion, arachidonic acid metabolism, procoagulant responses, pla- let adhesion under static or flow conditions, flow cytometry, and production of microparticles. Although one would ideally wish to perform experiments with human platelets, studies within the circulation using intravital microscopy require the use of animal models, which are described in Chapter 16, vol. 1.

The main aim of this fourth volume is to complement the first three volumes published in 2004 and 2012 by adding advanced methodologies and perspectives. Chapters guide readers through new techniques into the study of platelets and megakaryocytes, including new imaging approaches, new methods for platelet production in vitro, and systems biology approaches. Written in the highly successful Methods in Molecular Biology series format, methods chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and vital tips on troubleshooting or avoiding known pitfalls. Authoritative and up-to-date, Platelets and Megakaryocytes: Volume 4, Additional Protocols and Perspectives adds a wealth of new expertise for the labs of scientists working in this key biological area of study.

David Kuter and a host of leading international researchers summarize in one volume all the knowledge of thrombopoietins (TPO) available today. The distinguished experts review the history of the search to discover TPO, describe the molecular and biological characteristics of this new molecule, and present the results of the preclinical animal experiments that will guide clinical use of this new hormone. Along the way they provide the most recent and comprehensive guide to the biology of megakaryocytes and platelets.

Blood Cell Biochemistry was initially conceived as part of the Plenum series Subcellular Biochemistry, from which it has developed into a separate series. The present volume is devoted primarily to contributions on megakaryocytes and platelets and, to a lesser extent, to macrophages and eosinophils. The book does not attempt a rigorous or total coverage of the particular topics; it represents the areas of current scientific activity and interest that were selected by the editor at the commencement of this project. In general, the approach has been similar to that adopted for Volume 1 of the series (Erythroid Cells); the same approach will be followed subsequently in Volume 3 (Lymphocytes and Granulocytes). This book opens with a developmentally oriented chapter by Janine Breton-Gorius on megakaryocyte maturation and platelet release in normal conditions, which serves to set the scene ultrastructurally for much of the data that follow. The biosynthesis and process ing of platelet glycoproteins in megakaryocytes is dealt with by Alain Duperray and his colleagues, and thereby provides an in-depth biochemical survey of the megakaryocyte. The applications and strengths of crossed immunoelectrophoresis for the study of platelet membrane proteins is then covered by Simon Karpatkin, and a detailed account of the heredity disorders of platelet function is provided by Francine Rendu and Evelyne Dupuy.

New techniques to study cell signaling and function can develop at a staggering pace; however, many approaches are as valid today as on the day they were established. Thus, the main aim of Platelets and Megakaryocytes: Volume 3, Additional Protocols and Perspectives is to complement the first two volumes published in 2004 by adding recently developed state of the art techniques. Conveniently divided into three sections, this detailed volume covers techniques to study platelet function, approaches to investigate megakaryocyte function, and perspectives on important overall concepts in the field of megakaryocyte and platelet biology. Written in the highly successful Methods in Molecular BiologyTM series format, methods chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and vital tips on troubleshooting and avoiding known pitfalls. Authoritative and up-to-date, Platelets and Megakaryocytes: Volume 3, Additional Protocols and Perspectives adds a wealth of new expertise for the labs of scientists working in this key biological area of study.

This book gives a comprehensive insight into platelet biogenesis, platelet signal transduction, involvement of platelets in disease, the use of diverse animal models for platelet research and future perspectives in regard to platelet production and gene therapy. Being written by international experts, the book is a concise state-of-the art work in the field of platelet biogenesis, biology and research. It represents an indispensable tool for research scientists in biomedicine, vascular biology, hematopoiesis and hemostasis and specifically for scientists in platelet research, as well as for clinicians in the field of hematology and transfusion medicine.​
