Investigations of the role of the Pipe sulfotransferase in the establi

The Drosophila dorsal group gene pipe provides the crucial link that transmits dorsal-ventral (DV) polarity information from the ovary to the embryo. Females homozygous for mutations in pipe produce dorsalized embryos. pipe encodes ten protein isoforms with amino acid sequence similarity to vertebrate glycosaminoglycan 2-O-sulfotransferases, suggesting that Pipe functions by modifying a carbohydrate-bearing molecule that controls embryonic DV patterning. Two major components of my project have been to examine the functional specificities of different Pipe isoforms and to identify Pipe's enzymatic substrate and learn how it participates in DV pattern formation.;I have used two approaches to investigate whether the various Pipe isoforms… [cont.]

Polarity regulation during neuronal migration and differentiation.
Store: Barnes & Noble
Price: $32.34 USD • Compare Prices ►
Condition: new

A key requirement of normal brain development is that during their proliferation, migration and differentiation precursors and daughter neurons establish and maintain a specific cell polarity, defined as having one or more axes of symmetry. Cell polarization divides the cell into different functional domains and facilitates the orientation of neurons within the overall brain framework, allowing functional connections to be established. In this dissertation I will describe work I have performed to address the question of how cell polarity is regulated during neuron migration and differentiation. I will address how the cytoskeleton and cell polarity are dynamically regulated in migrating neurons of the embryonic and adult forebrain.… [cont.]

Integration of soluble and adhesive signals during fibroblast migratio

Condition: new

Cell migration is found in everyday biological processes including embryogenesis, cancer metastasis, and wound healing. During wound healing, fibroblasts must detect and transform soluble (platelet-derived growth factor) and adhesive (fibronectin) stimuli into directed movement in order to rapidly invade the wound to facilitate repair.;In fibroblasts and many other cells, activation of the phosphoinositide 3-kinase (PI3K) pathway is required for certain motility processes. PI3Ks generate specific 3' PI lipid products which act as membrane second messengers, and the spatial pattern of 3' PI density in the membrane is thought to control the directionality of membrane protrusion and cell migration. Using a specific 3' PI lipid fluorescent-bios [cont.]

Mechanisms of CDC-42 regulation in asymmetric cell divisions of Caenor

Price: $26.47 USD • Compare Prices ►
Condition: new

Attaining a defined axis of polarity is necessary for a cell to execute diverse functions, such as directed motility, the generation of daughter cells with disparate fates and for the morphogenesis of ensembles of cells into organs. In C. elegans, a polarizing cue triggers actinomyosin-driven cortical flows that segregate intracellular determinants that maintain polarity and signal asymmetric cell division. The polarization and asymmetric cleavage of the fertilized oocyte is a model system for understanding mechanisms of cell division conserved among animal cells, including those mechanisms by which the partitioning defective (PAR) proteins and Rho-family GTPases transduce an axis of polarization into an asymmetric cell cleavage.;To… [cont.]

Embryonic stem cell differentiation in defined medium.
Store: Barnes & Noble
Price: $32.34 USD • Compare Prices ►
Condition: new

Embryonic stem (ES) cells which are derived from the epiblast in the preimplantation embryo can be propagated indefinitely in an undifferentiated state in culture and have an ability to give rise to various types of cells including neural cells. Most previously published protocols for mouse ES cell neural differentiation involve induction by retinoic acid (RA) or by exposure to mitogens, or medium containing proprietary supplements or conditioned by other cell types. In this thesis, we developed completely defined serum-free and retinoid-free differentiation (SFD) medium, and compared physiological, molecular and phenotypic characteristics of neurons differentiated in SFD medium with or without transient exposure to RA. Mouse ES cells… [cont.]

Illustrates the processes of pollination and fertilization. Separates into seven parts. As your students explore this greatly enlarged model, they will discover the arrangement of floral components, and the reproductive function of flowers. In fact, because the petals, sepals and stamens are detachable, your students can begin the investigation with the model disassembled, and build the flower as they learn about its parts and their functions - reinforcing the educational experience.One anther is sectioned open to reveal the pollen grains within. Adhering to the stigma are six pollen grains, demonstrating the process of pollination. One of these grains has generated a pollen tube which has entered the ovary.

Ceramide is considered a key sphingolipid, regulating a variety of critical cellular processes. To facilitate the study of ceramide localization and its interaction with cellular proteins, we have developed a novel antibody against ceramide, raised in rabbit (rabbit Ig G). The novel antibody specifically recognizes ceramide in lipid overlay assays and detects ceramide containing different fatty acid chain lengths (ie C2-, C16-, C18-, C20- and C24 ceramide). The new antibody was compared with the commercially available anti-ceramide mouse Ig M antibody in immunocytochemistry experiments to study the localization of ceramide. Although both antibodies stain similar regions on the cell membrane, the rabbit Ig G reveals the distribution of… [cont.]

Maternal Control of Development in Vertebrates

Condition: new

Eggs of all animals contain m RNAs and proteins that are supplied to or deposited in the egg as it develops during oogenesis. These maternal gene products regulate all aspects of oocyte development, and an embryo fully relies on these maternal gene products for all aspects of its early development, including fertilization, transitions between meiotic and mitotic cell cycles, and activation of its own genome. Given the diverse processes required to produce a developmentally competent egg and embryo, it is not surprising that maternal gene products are not only essential for normal embryonic development but also for fertility. This review provides an overview of fundamental aspects of oocyte and early embryonic development and the… [cont.]
