Over the last decade the volume Membrane Fusion. edited by Poste and Nicholson, has probably served as one of the major sources of review in­ formation on fusion in membrane systems. Since its publication much new information has been collected. New methods of inducing fusion have been invented or discovered, and new applications for fusion have been found. The need for an up-to-date monograph that covers and in­ tegrates these subjects, reviews established material, and rationalizes and integrates the old and the new is thus obvious. This book is the product of efforts to meet this need. Most of the current work in the field of membrane fusion takes place within the context of intact or modified cells. Hence this book emphasizes the plasma membrane. Each chapter is either a review, a report, or a short historical overview, depending, respectively, on whether the subject is large in scope and has a long history, or the subject is in such an early stage of development that most of what is known is still in the hands of a relatively small number of investigators and is best covered in report form.

Cells can be funny. Try to grow them with a slightly wrong recipe, and they turn over and die. But hit them with an electric field strong enough to knock over a horse, and they do enough things to justify international meetings, to fill a sizable book, and to lead one to speak of an entirely new technology for cell manipulation. The very improbability of these events not only raises questions about why things happen but also leads to a long list of practical systems in which the application of strong electric fields might enable the merger of cell contents or the introduction of alien but vital material. Inevitably, the basic questions and the practical applications will not keep in step. The questions are intrinsically tough. It is hard enough to analyze the action of the relatively weak fields that rotate or align cells, but it is nearly impossible to predict responses to the cell-shredding bursts of electricity that cause them to fuse or to open up to very large molecular assemblies. Even so, theoretical studies and systematic examination of model systems have produced some creditable results, ideas which should ultimately provide hints of what to try next.
