Basic Cell Culture Protocols
Author: Jeffrey W. Pollard
language: en
Publisher: Springer Science & Business Media
Release Date: 1997
Now completely revised and updated from the original, much-acclaimed and bestselling first edition, Basic Cell Culture Protocols, 2nd ed. offers today's most comprehensive collection of easy-to-follow, cutting-edge protocols for the culture of a wide range of animal cells. Its authoritative contributors provide explicit, step-by-step instructions, along with extensive notes and tips that allow both experts and beginners to successfully achieve their desired results. Topics range from basic culture methodology to strategies for culturing previously uncultured cell types and hard-to-culture differentiated cells. Methods are also provided for the analysis of living cells by FACS, video microscopy, and confocal microscopy. Like the first edition, this book should be in every cell culture laboratory and be of use to all who use cell cultures in research.
Cancer Cell Culture
This volume explores the latest collection of cell models that are used in preclinical cancer research, and covers both two-dimensional and three-dimensional culturing techniques. The chapters in this book are divided into two parts. Part One discusses two-dimensional cancer cell culture, cell models at the Air-Liquid Interface, and the latest advancements in three-dimensional complex spheroid models and dedicated disease animal models. Part Two contains technical chapters that illustrate step-by-step methodologies for specific cancer cell culture methods. The methods discussed range from the generation of isogenic cancer cell lines, the use of serum-free growth conditions, and three-dimensional cell cultures and their specific assays for the efficacy assessment of new anticancer therapies. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Cutting-edge and comprehensive, Cancer Cell Culture: Methods and Protocols is a valuable tool to help researchers involved in this important field to further improve or advance their models for cancer research.
Natural Killer Cells in Human Diseases: Friends or Foes?

NK cells are lymphocytes of the innate immune system that share some features with adaptive immune cells like T cells. They are well known for their importance to control viral infections and tumor development, but also intracellular bacterial and parasitic infections. A balance between negative and positive signals transmitted via germ line-encoded inhibitory and activating receptors controls the function of NK cells. Activated NK cells respond by killing the infected or tumor cells without prior sensitization, and by producing cytokines and chemokines. It has been shown that NK cells cross-talk with other immune cells, such as dendritic cells and macrophages, can shape T cell and B cell immune responses through direct interactions as well as by virtue of their cytokine/chemokine production. NK cells can also regulate immune responses by killing other immune cells, including activated T cells, or by producing anti-inflammatory cytokines upon excessive inflammation. However, NK cells are not friends in all situations. Indeed, it has been shown in LCMV-infected murine models that, depending on the viral inoculation load, NK cells may either help fight infection or can promote chronic infection. Moreover in cancer models, it has been shown that NK cells can kill anti-tumoral T cells. Recent studies of NK cells in patients with cancer support the notion of detrimental roles of NK cells. Furthermore, studies implicate NK cells in contributing to both graft rejection and tolerance to an allograft. In some autoimmune diseases, like rheumatoid arthritis, NK cells may promote disease pathogenesis. The scope of this Research Topic is to present and discuss knowledge on the role of NK cells in various diseases settings: viral infections as well as other infections, cancer, transplantation, and autoimmunity. The aim is to discuss how NK cells respond during disease and specifically when, why and how NK cells can be harmful and if they exert different functions (production of specific cytokines, inhibition of other immune cells through other mechanisms beside cytotoxicity) in these situations. Which are the NK cell subsets that play beneficial or deleterious roles in these diseases? Are there different phenotypes associated with protective NK cells (e.g. antiviral, antitumoral) and NK cells involved in disease pathogenesis? How are these diverse NK cells activated and do they function primarily through direct cytotoxicity, ADCC or cytokine and chemokine production? What are the signals or interactions that can change and shape the NK cell response shifting them from protective to harmful? We thank the authors that submitted reviews and original research manuscripts that help to better understand these questions, with the aim that this will help the scientific community to determine what could be the main future research directions to better understand the role of NK cells in disease protection or development.
