Patterning and Cell Type Specification in the Developing CNS and PNS, Second Edition, the latest release in the Comprehensive Developmental Neuroscience series, presents recent advances in genetic, molecular and cellular methods that have generated a massive increase in new information. The book provides a much-needed update to underscore the latest research in this rapidly evolving field, with new section editors discussing the technological advances that are enabling the pursuit of new research on brain development. This volume focuses on neural patterning and cell type specification in the developing central and peripheral nervous systems. Features leading experts in various subfields as section editors and article authors Contains articles that are peer reviewed to ensure accuracy, thoroughness and scholarship Covers mechanisms which control regional specification, regulate proliferation of neuronal progenitors, control differentiation and survival of specific neuronal subtypes, and control the development of non-neural cells
Signalling by morphogens such as the Hedgehog family, Notch, Wingless/Wnt and various growth factors is essential during embryogenesis. The establishment of concentration gradients of these morphogens plays a key role during developmental patterning in all multicellular organisms, assuring that distinct cell/tissue types and organs appear at the right place in the right time during embryogenesis. Regulation of morphogen synthesis, trafficking and diffusion are all known to play a part in setting up these gradients, and a complex web of signaling mechanisms ensures that specific responses occur at the correct threshold concentration in the recipient cells whose fate depends on these morphogens.
How the tissues of a developing organism are reproducibly patterned has been a major question in biology. Under adequate conditions, a single fertilized cell can generate a full variety of mature cell types and organize them into a developed organism. In order to accomplish these complex tasks of self-organization, positional and temporal information must be provided to individual cells to ensure that the right developmental events occur at appropriate times. This is at least partially assisted by the specification of spatial and temporal axes formed and maintained during development. One way to define position and time within a developing organism is to form spatial or temporal gradients of signaling molecules, which patterns tissues in a concentration-dependent manner. A critical challenge of such gradient based patterning mechanisms is to maintain the desired gradient profiles of signaling molecules in a heterogeneous and fluctuating cellular environment. In this thesis, I describe how spatial and temporal gradients of signaling molecules can be refined and maintained during development of the model organism Caenorhabditis elegans. Using quantitative measurement techniques and analyses, I find that such tasks can be achieved by the balance between the activities of gradient forming signaling molecules and their antagonistic counterparts.
Escherichia coli, commonly referred to as E. coli, has been the organism of choice for molecular genetics for decades. Its machinery and mobile behavior is one of the most fascinating topics for cell scientists. Scientists and engineers, not trained in microbiology, and who would like to learn more about living machines, can see it as a unique example. This cross-disciplinary monograph covers more than thirty years of research and is accessible to graduate students and scientists alike.
