Available in PDF, EPUB and Kindle. Book excerpt: Sea urchin eggs are objects of wonder for the student who sees them for the first time under the microscope. The formation of the fertil ization membrane after insemination, the beauty of mitotic cleavage, the elegant swimming of embryos, remain an esthetic pleasure even for the eyes of seasoned investigators. But sea urchin eggs have other, more practical, advantages: they lend themselves to surgical operation without difficulty and they heal perfectly; they can be obtained in very large amounts and represent thus an extremely favorable material for biochemists and molecular embryologists. It is not surprising that, in view of these exceptional advantages, sea urchin eggs have attracted the interest of innumerable biologists since O. HERTWIG discovered the fusion of the pronuclei (amphimixy), in Paracentrotus lividus, almost a century ago. The purpose of the present book is to present, in a complete and orderly fashion, the enormous amount of information which has been gathered, in the course of a hun dred years of sea urchin embryology. JOSEPH NEEDHAM, in 1930, was still able to present all that was known, at that time, on the biochemistry of all possible species of developing eggs and embryos in his famous "Chemical Embryology" (Cambridge University Press) . It would no longer be possible for one man to write a modern version of what was a "Bible" for the young embryologists of forty years ago.

Available in PDF, EPUB and Kindle. Book excerpt: This book should be regarded as the continuation to my previous book Developmental Biology of the Sea Urchin Embryo, edited by the Academic Press in 1973, rather than as a new edition. Due to the exceedingly high rate of development in this field (something like 2000 papers have been published on this subject in these last 10 years), I preferred, in fact, not to describe again in detail the enormous amount of the old literature, as was attempted in my previous book, but to briefly summarize the state of the art in each problem and to describe in some detail the experiments per formed in the last 12 years. In doing so, more emphasis was given to the more recent ones and to those which can be considered as corner stones in each subject. Care was, however, taken to mention the reviews or key papers in which the reader can find a source of the details of the older literature, besides refering him to my previous book.

Download or read book Primary Mesenchymal Cells written by F. Koller and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: The human body contains many specialized tissues that are capable of fulfilling an incredible variety of functions necessary for our survival. This volume in the Human Cell Culture Series focuses on mesenchymal tissues and cells. The in vitro study of mesenchymal cells is perhaps the oldest form of human cell culture, beginning with the culturing of fibroblasts. Fibroblasts have long been generically described in the literature, arising from many tissue types upon in vitro cell culture. However, recent studies, many enabled by new molecular biology techniques, have shown considerable diversity in fibroblast type and function, as described within this volume. Mesenchymal tissue types that are described within include bone, cartilage, tendons and ligaments, muscle, adipose tissue, and skin (dermis). The proper function of these tissues is predominantly dependent upon the proper proliferation, differentiation, and function of the mesenchymal cells which make up the tissue. Recent advancements in primary human mesenchymal cell culture have led to remarkable progress in the study of these tissues. Landmark experiments have now demonstrated a stem cell basis for many of these tissues, and, furthermore, significant plasticity and inter-conversion of stem cells between these tissues, resulting in a great deal of contemporary excitement and controversy. Newly-developed mesenchymal cell culture techniques have even lead to novel clinical practices for the treatment of disease.
Download or read book Calcification in Biological Systems written by Ermanno Bonucci and published by CRC Press. This book was released on 1992-05-26 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calcification in Biological Systems provides a collection of up-to-date papers regarding calcification in a variety of biological systems. The papers are not simple reviews of the literature. Each paper reflects the personal experience of the author(s) and is rich in constructive criticism and suggestions. Topics range from basic molecular processes to general structural problems in systems as different as unicellular organisms and human skeletal tissues. Because calcification is so diffuse in the animal kingdom, this book makes no attempt to achieve a conclusive synthesis of available results and current ideas. Instead, its merit lies in its ability to be useful to investigators with different scientific backgrounds and areas of interest.

Download or read book Gastrulation written by Ray Keller and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gastrulation is a fundamental process of early embryonic development. It involves virtually every aspect of cell and developmental biology and results in the formation of fundamental structural elements around which a developing animal's body plan is organized. As such it is not only an important process, but also one that is complicated and not easily dissected into its component parts. To understand the mechanisms of gastrulation one must acknowledge that gastrulation is fundamentally a biomechanical process (that is, a problem of cells generating forces in a three dimensional array, patterned in space and time such that appropriate tissue movements are executed). Three intertwined questions emerge: what cell activities generate forces, how are these cell activities patterned in space and time, and how are the resulting forces harnessed in three dimensional domains? To address these issues it is important to define and characterize regional cell behaviors and to learn how they are patterned in the egg and/ or by subsequent cell and tissue interactions. At the biochemical level, what are the cellular and extracellular molecules that control cell behavior? Finally, how are specific patterns of cellular activity integrated to produce tissue behavior? The task of answering the above questions, an immense task in itself, is compounded by the fact that the morphogenetic movements of gastrulation and their underlying mechanisms vary between different organisms.
Download or read book Stem Cells in Marine Organisms written by Baruch Rinkevich and published by Springer Science & Business Media. This book was released on 2009-10-03 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Do real stem cells and stem cell lineages exist in lower organisms? Can stem cells from one organism parasitize the soma and/or the germ line of conspecifics? Can differentiated cells in marine organisms be re-programmed to regenerate tissues, organs and appendages through novel de-differentiation, transdifferentiation, or re-differentiation processes, leading to virtually all three germ layers, including the germline? The positive answers to above questions open a new avenue in stem cell research: the biology of stem cells in marine organisms. It is therefore unfortunate that while the literature on stem cell from terrestrial organisms is rich and expanding at an exponential rate, investigations on marine organisms’ stem cells are very limited and scarce. By presenting theoretical chapters, overview essays and specific research results, this book summarises the knowledge and the hypotheses on stem cells in marine organisms through major phyla and specific model organisms. The study on stem cells from marine invertebrates may shed lights on mechanisms promoting immunity, developmental biology, regeneration and budding processes in marine invertebrates, body maintenance, aging and senescence. It aims in encouraging a larger scientific community to follow and study the novel phenomena of stem cells behaviours as depicted from the few currently studied marine invertebrates.
