Cell Somatic

The authors of this absorbing new book describe the science of gene therapy in terms easily accessible to the non-specialist, and focus on the controversial ethical and public policy issues surrounding human interventions in human heredity. After a brief survey of the structure and functions of DNA, genes, and cells, Walters and Palmer discuss three major types of potential genetic intervention: somatic cell gene therapy, germ line gene therapy, and genetic enhancements. They start with the current techniques of gene addition, using non-reproductive (somatic) cells in an effort to cure or treat disease. Next they address the technical problems and moral issues facing attempts to prevent disease through genetically modifying early human embryos or sperm and egg cells. These changes would be passed on to future generations. Chapter 4, in many ways the most original part of this volume, confronts the issue of employing genetic means to improve human abilities and appearance. Depending on the technique, such enhancements could affect not only the individuals receiving the intervention but their offspring as well. Three types of genetic enhancements are considered: physical alterations to improve size, reduce the need for sleep, and decelerate aging; intellectual enhancements of memory and general cognitive ability; and moral enhancements for control of violently aggressive behavior. The authors maintain that genetic modifications should be evaluated individually rather than be condemned in principle or as a group. The final chapter summarizes the public review process that human gene therapy proposals have been undergoing in the United States since 1990. Five appendices, providing technicalbackground information along with a complete list of questions raised in the national public review process, supplement the discussion.

In this third edition the authors have written a guide to the essentials of plant tissue culture. The book takes the reader through a graded series of experimental protocols and provides an introductory review of each topic. There are discussions of aseptic techniques, and nutritional components of media. Subsequent chapters cover such topics as callus formation, organogenesis, xylem cell differentiation, root cultures, cell suspensions, micropropagation by buds, somatic embryogenesis, protoplast culture and fusion, secondary metabolite production, and quantitation of procedures. A glossary, commercial sources of supplies, and the formulations of culture media are also included. This new edition has been completely revised and updated. The organization has been improved, and new illustrations have been added, together with new experiments on such topics as potato callus formation, and embryo culture. This book will be useful to graduate students and professionals in plant science, forestry, agronomy, and horticulture.

Somatic cell - A somatic cell is generally taken to mean any cell forming the body of an organism: the word "somatic" is derived from the Greek word sōma, meaning "body". Somatic cells, by definition, are not germline cells and cannot divide or differentiate to produce a new generation of offspring under any circumstances.

Somatic cell count - Somatic cell count (SCC) is one of indicators of the quality of milk. Somatic cells are body cells, including leucocytes (white blood cells).

Somatic cell nuclear transfer - In genetics, somatic cell nuclear transfer (SCNT) is a technique for cloning.

Cytotoxic T cell - A cytotoxic (or TC) T cell is a T cell (a type of white blood cell) which has on its surface antigen receptors that can bind to fragments of antigens displayed by the Class I MHC molecules of virus (or other intracellular pathogen) infected somatic cells and tumor cells.
