Germline Development Chairwoman: Anne McLaren 1994 The germline is the cell lineage that forms the link between generations and is, potentially, immortal. In animals that reproduce sexually, the germ cells undergo sexual differentiation and genetic recombination. Despite its importance, the development of the germline is an area of biology that, until recently, had been relatively neglected because of the technical difficulties associated with working with very early embryos. However, over the last few years, improved cell culture techniques, the availability of specific markers for germ cells and the identification of genes involved in germ cell specification have enabled rapid progress to be made in our understanding of the processes involved. This book links classical, cellular descriptive studies with more recent work on the molecular and genetic aspects of germline development. Contributions from some of the leading scientists in this field describe studies on a range of organisms, including insects, worms, birds, fish, amphibia, mammals and green algae. The topics covered include the specification of the germ cells, their migration to the gonads and subsequent interactions with the soma, and gametogenesis. Evolutionary aspects of germ cell segregation are also considered.

This book introduces readers to the fascinating interaction of specialized gamete cells, forming the early embryo and a blueprint of new life. Readers will gain a thorough understanding of the complex physiological events and mechanical processes - such as ionic regulation, metabolism and intracellular signalling - to decipher cause and effect in fertilization. Wide-ranging in its approach, this book describes fertilization as a highly conserved mechanism throughout the animal kingdom, taking case studies from echinoderms, ascidians, amphibians and mammals through to other phyla. An excellent companion to undergraduate and postgraduate students of medicine, veterinary and biological sciences, this text provides an underpinning of the mechanisms of fertilization that inform assisted reproduction practice and research in medicine and agriculture. Explores the detailed phases before fertilization: the oocyte as a quiescent cell, attracting its partner gamete, followed by a cascade of pre-determined physiological events, to form the dynamic zygote cell; setting the scene for the early embryo, and beyond.

The completion of the human genome and technological advances developed by the Human Genome Project have dramatically changed our understanding of the mechanisms underlying the development and differentiation of male germ cells, and our ability to investigate such mechanisms. This book is a timely document of advances made in the field of male gonad and germ cell research in the postgenomic era. The coverage includes the role of Y chromosome genes in male reproduction, gene expression in spermatogonial stem cells and male germ cells, and the regulation of germ cell genes in reproduction and in
