  • Publication number: 20150212413
    Abstract: A photosenstive resin composition is prepared by dispersing at least one of a hydrophobic polymer and a mixture of an oil-soluble photopolymerization initiator and a water-insoluble or sparingly water-soluble compound having at least one photoactive, ethylenically unsaturated group in an aqueous solution that contains both a water-soluble polymer and a diazo resin is obtained by condensing a water-soluble salt of an optionally substituted 4-diazodiphenylamine with formaldehyde in the presence of sulfuric acid and phosphoric acid. This photosensitive resin composition gives a photosensitive film having excellent stability over time and a wide exposure latitude. By adding a specific fluorine compound to the photosensitive resin composition, a screen plate has an excellent discharge performance.

  • Patent number: 8232052
    Abstract: In neuron transplantation therapy, in terms of safety, it is preferable to use a cell population consisting only of a desired type of cells, and to use postmitotic neurons in consideration to avoid the risk of tumorigenesis. Moreover, greater therapeutic effects would be expected through the use of earlier progenitor cells in consideration of post-transplantation viability, proper network formation ability, and such. According to the present invention, Lrp4, a gene that is specifically expressed in dopaminergic neuron proliferative progenitor cells prior to cell cycle exit, was identified. The use of Lrp4 expression in cells as an index allows for the isolation. of cells suitable for transplantation therapy of neurodegenerative diseases such as Parkinson's disease in terms of safety, survival rate, and network formation ability.
