Neurotrophins and the Neural Crest
The target of much current research, the neural crest is a transitory tissue of the vertebrate embryo that gives rise to many diverse structures in the adult organism, including the autonomic nervous system, the enteric nervous system, and most primary sensory ganglia, among other cell types and tissues. Reflecting recent investigations, Neurotrophins and the Neural Crest is dedicated to the roles neurotrophins play in neural crest cell differentiation and in the survival of neural crest derivatives. This timely book correlates in vitro data with results obtained from knock-out mice with targeted neurotrophin or receptor deletions, with the goal of determining the fidelity and usefulness of ...
Neural Crest Stem Cells
The book offers readers an understanding of the development of neural crest cells, which is crucial as many birth defects and tumours are of neural crest origin. The neural crest is a transient tissue of the vertebrate embryo. It originates from the future spinal cord and neural crest stem cells emigrate from this location to various places in the embryo, giving rise to many different cell types and tissues. Neural crest derivatives include the peripheral nervous systems, endocrine cells such as the adrenal medulla, smooth musculature of the cardiac outflow tract and great blood vessels, as well as craniofacial bone and cartilage. The underlying mechanisms that regulate embryonic neural crest development are still being investigated and are important for our understanding of neural crest pathologies. Readers will have ready access to current research topics, elaborated in great detail, with a focus on adult neural crest-derived stem cells, which persist in various locations of the postnatal organism. Delving into stem cells from different locations of the body, the book explores the best possible source of such cells for future use in medical applications.
Cell Culture in the Neurosciences
A fundamental problem in neuroscience is the elucidation of the cellular and molecular mechanisms underlying the development and function of the nervous system. The complexity of organization, the heteroge neity of cell types and their interactions, and the difficulty of controlling experimental variables in intact organisms make this a formidable task. Because of the ability that it affords to analyze smaller components of the nervous system (even single cells in some cases) and to better control experimental variables, cell culture has become an increasingly valuable tool for neuroscientists. Many aspects of neural development, such as proliferation, differentiation, synaptogenesis, and my...
Control of Gene Expression by Catecholamines and the Renin-Angiotensin System
The special issue of Molecular and Cellular Biochemistry focuses on `Control of Gene Expression by Catecholamines and the Renin-Angiotensin System' in health and disease. In recent years, great progress has been made in the understanding of catecholamine and angiotensin II modulated gene expression. There is also increasing evidence that catecholamine and angiotensin II induced cellular injury not solely arises from classical pathways but also from a perturbed gene expression. Taking into account that catecholamines and angiotensin II are vital for a balanced gene expression of many cells, the intriguing possibility arises that various disease are initiated or aggravated by such an imbalance...

The Merkel Cell
Since their first description in 1875, Merkel cells have remained an elusive cell type. Their origin as well as their classification as mechanoreceptors have been a matter of controversy and intense discussion. The peptidergic granules in these cells are suggestive of neuroendocrine functions, but their discovery has raised additional questions regarding Merkel cell function. Essential aspects of structure, development and function of normal Merkel cells and Merkel cell carcinoma are presented in short chapters, providing concise and up-to date information on this fascinating cell type.
