Book Description
Cellular polarization is key to all cellular functions. Our perceptions, which are derived from our senses, depend on the proper cellular polarization of our sense organs, such as the eyes or ears. Much of this book examines the different aspects in cellular polarization and its researched role in the Drosophila, where the first planar cellular polarity (PCP) gene was discovered over 20 years ago. Topics also include: From flies to man: how we are polarized, Marking an embryo work, Cellular polarization at its functional best, Hearing and seeing your environment, and From a cell to an organ.This series represents timely issues in developmental biology. It provides annual reviews of selected topics, written from the perspectives of leading investigators in the field of development.* Presents many various organisms such as flies, fish, frogs and mice* Offers over 40 exceptional illustrations* First of its kind to include new data and detailed models on cell planar polarization

Book Description
Cell Polarity in Development and Disease offers insights into the basic molecular mechanisms of common diseases that arise as a result of a loss of ordered organization and intrinsic polarity. Included are diseases affecting highly polarized epithelial tissues in the lung and kidney, as well as loss and gain of cell polarity in the onset and progression of cancer. This book provides a basic resource for understanding the biology of polarity, offering a starting point for those thinking of targeting cell polarity for translational medical research. - Provides basic science understanding of cell polarity disease and development - Covers diseases affecting polarized epithelial tissues in the lung and kidney, also covering the progression of cancer - Includes historical context of cell polarity research for potential future breakthroughs

Book Description
Intracellular cell signaling is a well understood process. However, extracellular signals such as hormones, adipokines, cytokines and neurotransmitters are just as important but have been largely ignored in other works. Aimed at medical professionals and pharmaceutical specialists, this book integrates extracellular and intracellular signalling processes and offers a fresh perspective on new drug targets.

Book Description
The establishment of polarity is a fundamental feature in eukaryotic development. Polarity in Plants provides an account of current research into the mechanisms by which polarity is generated at the level of the cell, organ and organism in plants, drawing especially on recent work with model organisms. The emphasis is on the use of the techniques of molecular genetics to dissect molecular mechanisms. This is the first volume to bring together the diverse aspects of polarity in plant development.

Book Description
This work provides a state-of-the art overview on the most relevant aspects of cell polarity. Volume 2 discusses the physiological and pathophysiological relevance of cell polarity. It especially focuses on pathophysiological conditions in which one or several aspects of cell polarity are impaired, and in which a loss of cell polarity possibly contributes to disease (e.g. epithelial-to-mesenchymal transition in cancer, role of polarity proteins in cancer). Both volumes are intended for professors, group leaders and researchers in cell biology as well as for medical professionals working in anatomy, cell biology, physiology, pathology and tumor biology.

Book Description
Abstract Establishing Planar Cell Polarity in an Edgeless Epithelium By Katherine Ruth Lipari Doctor of Philosophy in Molecular and Cell Biology University of California, Berkeley Professor David Bilder, Chair In all animals, organ function is dependent on two major processes that happen in the very beginning of embryonic development: differentiation and morphogenesis. In this study we focus on the process of morphogenesis, studying the planar cell polarity (PCP) pathway, a process that acts perpendicular to the apical-basal axis to orient the cell within the larger environment. From the elongation and closure of the entire central nervous system during neural tube closure, to the subtle orientation of hairs on the skin of a mammal, PCP dictates gross morphological events by first polarizing subcellular structures. Most of our knowledge about PCP derives from the Drosophila wing, where two well-characterized signaling pathways are currently known to regulate PCP: Fz/Vang PCP and Fat/Ds signaling. These two pathways have also been implicated in vertebrate PCP; despite vigorous investigation, there is a surprising paucity of data on how these pathways are shaping vertebrate organs, beyond the fact that they do. One major limitation is that PCP has been most deeply studied in organs with a fundamentally different topology than the tubules that make up the majority of animal organs. While planar polarization of proteins within the cells of the Drosophila wing align with the edge of the wing, causing elongation in the direction of polarization, vertebrate planar polarity proteins align perpendicular to later elongation and do not orient towards the edge of the tissue. Indeed, vertebrate tubular organs do not have similar edges to dictate orientation; they are 'edgeless' tissues. To study how planar polarization occurs in such structures we use the Drosophila egg chamber as a model. This tissue undergoes planar polarization perpendicular to the axis of elongation - similar to other tubule elongation - and depends upon the Fat2 cadherin for planar polarization and elongation. In this dissertation I show that planar polarization in this tissue is established early during development of the tissue - at the level of a few cells - by biased microtubule growth. This bias is then propagated by rotation of the entire tissue to create planar polarization of the overlying extracellular matrix to establish a persistent orientation as the tissue grows. I find novel genetic enhancers of the Fat2 mutant phenotype that identify genes involved in this early event and later morphogenetic events. I also study what cells within the epithelium itself are necessary for this rotation to occur. Overall, my thesis work has shown how planar polarization is established and propagated in edgeless tissues through tissue migration.

Book Description
Amphibian embryos are supremely valuable in studies of early vertebrate development because they are large, handle easily, and can be obtained at many interesting stages. And of all the amphibians available for study, the most valuable is Xenopus laevis,which is easy to keep and ovulates at any time of year in response to simple hormone injections. Xenopusembryos have been studied for years but this is a particularly exciting time for the field. Techniques have become available very recently that permit a previously impossible degree of manipulation of gene expression in intact embryos, as well as the ability to visualize the results of such manipulation. As a result, a sophisticated new understanding of Xenopusdevelopment has emerged, which ensures the species’ continued prominent position among the organisms favored for biological investigation. This manual contains a comprehensive collection of protocols for the study of early development in Xenopusembryos. It is written by several of the field’s most prominent investigators in the light of the experience they gained as instructors in an intensive laboratory course taught at Cold Spring Harbor Laboratory since 1991. As a result it contains pointers, hints, and other technical knowledge not readily available elsewhere. This volume is essential reading for all investigators interested in the developmental and cell biology of Xenopusand vertebrates generally. Many of the techniques described here are illustrated in an accompanying set of videotapeswhich are cross-referenced to the appropriate section of the manual.
