    Notes: Successful regeneration of lesioned adult spinal cord in urodele (caudate) amphibians requires the action of injury-responsive ependymal cells (ependymoglia). The epithelial-to-mesenchymal transformation of ependymal cells following transection of the salamander spinal cord and the subsequent reformation of an epithelial tube have been described previously. A complete tissue culture model system has now been devised to study mesenchymal ependymal cells, epithelial ependymal cells, and ependymal/neuronal interactions in vitro. Here, we review critical aspects of substrate and growth factor environments required to produce mesenchymal ependymal cells in culture and present the first culture system for epithelial salamander ependymal cells and central nervous system neurons suitable for cell-cell interaction studies. Critical to ependymal epithelialization in culture is the removal of epidermal growth factor and addition of thrombin. Epithelialization occurs on tissue culture plastic as well as on permeable culture substrates. This culture system can now be used to determine the initial trigger for the ependymal response. A preliminary examination of ependymal/neuronal interactions shows that coculture of mesenchymal ependymal cells and central nervous system neurons prolongs survival of the neurons.

    Notes: Degeneration of dopaminergic neurons in the substantia nigra is associated with one of the most prominent human neurological disorders, Parkinson's disease. It is therefore of high interest to identify molecules with trophic effects on this neuronal population. We show here that the neuregulin receptor ErbB4 is differentially expressed in mesencephalic dopaminergic neurons, found in the substantia nigra and in a subregion of the ventral tegmentum but not in the retrorubral field. Early developmental onset and continued expression of ErbB4 into the adult and the presence of two high affinity ligands, neuregulin-1 and betacellulin, in the basal ganglia, suggested that these molecules might participate in the differentiation and/or maintenance of the nigrostriatal system. In order to address this hypothesis, we used a loxP flanked ErbB4 allele in combination with a nestin-Cre transgene and generated brain-specific ErbB4 null mice. These mutant animals survived into adulthood. The distribution of dopaminergic cell bodies in the midbrain, the expression of numerous genes specific to mesencephalic dopaminergic neurons, and the axonal projection to the basal ganglia all appeared normal. Finally, an assessment of their motor function revealed no behavioral deficits. The apparent lack of any mutant phenotype suggests the presence of a strong compensatory mechanism.

    Notes: A simple fabrication method is described which is capable of producing physically repeatable biconical tapers in optical fibers. A resistively heated platinum wire furnace provides the heat with standard fiber-optic positioning equipment to secure the fiber. The method does not require computer control and has the advantages of low cost, fast sample turn-around time, and the ability to concatenate multiple tapers on a single fiber. Experimental results demonstrating repeatable taper formation and the wavelength filtering property of the tapers is shown. Issues of varying the taper shape are addressed and measurement methods of the physical and optical characteristics are presented. Limited control of the taper symmetry is discussed, and recommendations for enhancement at the cost of simplicity are included.

    Notes: Through a longitudinal study of a mature family firm, this paper investigates the adoption and use of information technology in a family business. It is argued that the adoption and use of information technology is influenced by five key factors. These factors are discussed, leading to a presentation of a series of implications and conclusions.
