Book Description
This book comprehensively summarizes the biological mechanisms of coloration and pattern formation of animals at molecular and cellular level, offering up-to-date knowledge derived from remarkable progress in the last 10 years. The brilliant coloration, conspicuous patterns and spectacular color changes displayed by some vertebrates and invertebrates are generally their strategies of the utmost importance for survival. Consists of mainly three parts, starts with introductory chapter, such as Pigments and Pigment Organelles, Developmental Genetics of Pigment Cell Formation, Adult Pigment Patterns, and Color Changes, this book introduces new pigment compounds in addition to classically known pigments and organelles, explains how the generation of multiple types of pigment cell is genetically controlled, describes the mechanisms underlying the zebrafish stripe formation as well as other animals and also summarizes the mechanism of physiological and morphological color changes of teleost, amphibian and cephalopod. Written by experts in the field, this book will be essential reading for graduate students and researchers in biological fields who are interested in pigmentation mechanisms of animals.

Book Description
Pigment Cell Biology provides information on the growth of the pigment cell throughout its life cycle. This book explains how the pigment cell synthesizes its melanin. Organized into 34 chapters, this book begins with an overview of the factors that involved in governing the unique color pattern formation for three species of salamander. This text then explores the cranial and the caudal sections of the medullary plate that contribute to the pigment development of the head and the tail of amphibians. Other chapters consider the difference in the pituitary output of black and white axolotls. This book discusses as well the slow progress in the definition of the roles of the pituitary hormones in melanogenesis. The final chapter deals with a group of pigments that are derived by oxidation from tryptophan. This book is a valuable resource for embryologists, geneticists, histologists, physiologists, cytochemists, and endocrinologists. Comparative pathologists, biophysicists, and biochemists will also find this book useful.

Book Description
In the animal world, pigments and colour pigment patterns play an important role. Pigments in the epidermis offer protection against solar radiation, and the various colour patterns provide the animals with concealment, advertisement and disguise (Cott 1940). The study of pigment cells and colour patterns is a multidisciplinary research field which includes developmental biology (determination, differenti ation, migration), genetics (phenotypic gene expression, colour mutants), cell biology (ultrastructure, organelles, cell surface), biochemistry (enzymes, metabo lism), physiology (control of colour changes) and dermatology, as well as ecology and evolution. In the present study we investigate the development of two different amphibian larval pigment patterns. These patterns might serve as specific models for the arrangement of cells derived from the neural crest (NC), involving their migration, differentiation and interaction with each other and the embryonic environment. Because of the NC origin of pigment cells, we consider first some general aspects of NC development, before turning to pigment cells and specific problems in pigment pattern formation. The NC arises during neurulation, an early process in vertebrate embryoge nesis. In amphibians, the crest lies on top of the neural tube as a flat epithelial sheet or strand of cells (Detwiler 1937; Schroeder 1970; L6fberg and Ahlfors 1978; Spieth and Keller 1984). Here the term 'crest' is much more appropriate than in birds or mammals (Newgreen and Erickson 1986), where the crest cells start to migrate before a true crest has formed.

Book Description
The Vertebrate Pigmentary System: From pigment cells to Disorders provides readers with fundamental knowledge of the structural and functional aspects of vertebrate pigment cells - melanophores and melanocytes - from their origin to different stages of development to related diseases. Chapters of the book explain the specific regulatory receptors and markers, signaling pathways of skin melanocytes along with the diseases (hypopigmentation and hyperpigmentation) in humans associated with their disruption. Concurrently, the etiologies of pigmentary disorders and the various therapeutic approaches for their treatment are presented in focused chapters of the book with updated information from recent publications. A summary of natural product based treatment for hypopigmentation and hyperpigmentation rounds up the contents. This reference is a basic guide for medical students and dermatology residents, and a handy source of information for students, researchers, academicians in the field of pigment cell biology, pharmacology and cosmetology.

Book Description
Pigment Cell Growth covers the proceedings of the Third Conference on the Biology of Normal and Atypical Pigment Cell Growth. The book focuses on the nature of the pigment cell and its contained melanin. The selection first offers information on the origin of the mammalian pigment cell and its role in the pigmentation of hair and relations between developing melanophores and embryonic tissues in the Mexican axolotl. The book also examines the genetic control of pigmentation in the fowl; relationship of atypical pigment cell growth to gonadal development in hybrid fishes; and estrogen, thyroid hormone, and the differentiation of pigment cells in the brown leghorn. The publication takes a look at dendritic melanoblasts in metastatic squamous cell carcinoma; microscopic analysis of normal melanoblasts, nevus cells, and melanoma cells; and analysis of skin color in living human subjects by spectrophotometric means. The selection is a dependable source of data for readers interested in pigment cell growth.

Book Description
The most comprehensive and integrated book on pigmentation The Pigmentary System, Second Edition, gathers into one convenient, all-inclusive volume a wealth of information about the science of pigmentation and all the common and rare clinical disorders that affect skin color. The two parts, physiology (science) and pathophysiology (clinical disorders), are complementary and annotated so that those reading one part can easily refer to relevant sections in the other. For the clinician interested in common or rare pigment disorders or the principles of teaching about such disorders, this book provides an immediate and complete resource on the biologic bases for these disorders. For the scientist studying the biology of melanocyte function, the book provides a list of disorders that are related to basic biological functions of melanocytes. New features of this Second Edition include: Completely new section on the basic science of pigmentation – explaining the integration of melanocyte functions with other epidermal cells and with various organ systems like the immune system New chapters on pigmentary disorders related to intestinal diseases, the malignant melanocyte, benign proliferations of melanocytes (nevi) and phototherapy with narrow band UV All clinical chapters include the latest genetic findings and advances in therapy More than 400 color images of virtually all clinical disorders The book is ideal for all dermatologists and especially those interested in disorders of pigmentation. It is of particular use for pediatric dermatologists and medical geneticists caring for patients with congenital and genetic pigmentary disorders. This authoritative volume will fill the gap for dermatology training programs that do not have local experts on pigmentation. Basic and cosmetic scientists studying pigmentation and melanocytes will find the science and clinical correlations very useful in showing human significance and relevance to the results of their studies.
