Platelets and Megakaryocytes: Volume 1: Functional Assays / Edition 1

by Jonathan M. Gibbins, Martyn P. Mahaut-Smith

Overview

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.

Editorial Reviews

Reviewer: Eugene A Davidson, PhD (Georgetown University School of Medicine)
Description: This book, one of two volumes providing protocols for working with platelets, focuses on preparation and assays.
Purpose: The purpose is to provide protocols for laboratory use for investigators working with these formed elements of blood. This area is important and a compilation like this is useful. Objectives are largely met.
Audience: The target audience is laboratory personnel working with or planning to work with platelets. The editor has assembled an authoritative set of contributors.
Features: These formed elements of blood have major roles in coagulation pathways but are also associated with thromboses and cardiac problems. A number of drugs are targeted at various aspects of platelet interactions, especially aggregation. This contribution focuses on preparation and functional assays of both platelets and their precursor megakaryocytes. Since platelets are easily activated, their preparation requires very careful manipulations — thus, detailed protocols are valuable to laboratories working with them. In addition, once prepared, there are a number of assays that address diverse properties (nucleotide release, adhesion, aggregation, arachoidonate metabolism). Most of the relevant ones are provided here with sufficient detail to allow any laboratory to implement the procedures. The final section provides similar protocols for working with megakaryocytes, including culture methods. Each section is accompanied by a relevant bibliography. Laboratories working with platelets (including blood banks) will find this (and the companion volume) book a worthwhile addition.
Assessment: This is an important area of current study — the two volumes represent a reasonably comprehensive set of protocols and have value.
