    摘要: Multiple cell layers are formed with one cell layer formed on another cell layer. A carrier is provided having an alginate gel layer formed on a porous membrane. An extracellular matrix component gel layer or extracellular matrix component sponge layer may be formed on the alginate gel layer. A cell layer is formed on the alginate gel layer, or the extracellular matrix component gel layer or extracellular matrix component sponge layer. The alginate gel layer is solubilized such as with a chelating agent to exfoliate the cell layer from the porous membrane, and the exfoliated cell layer is placed on another cell layer on a carrier. The number of cell layers formed on each other may be 1-10, preferably 1-5, and more preferably 1-3.

    摘要: A semiconductor memory device is provided with a memory portion, a logical operation circuit which receives the data signal read out from such memory portion and the input data signal to form data to be offered to such memory portion, and a gate circuit. In case a data input operation is required which eliminates the logical operation, the input data signal is fed not via the logical operation circuit, but via the gate circuit directly to the memory portion. The semiconductor memory device constructed as above permits a high speed operation and is suited for use as the memory for image processing.

    摘要: A chemical sensor utilizing a chemical receptor (for example, one stimulating the sense of taste or smell) is provided. More specifically speaking, such a receptor is introduced into cells and the cells are immobilized on a support to form a chip. This chip is then employed as a component of a sensor. This sensor shows a reaction almost the same as the body's perception of the taste or smell or sense, thereby enabling analysis. Thus, it is also usable as an artificial sensory organ. Moreover, this sensor is usable in diagnosis, which imparts a high industrial usefulness to it.

    摘要: It is an object of the present invention to provide a method for detecting nerve stem cells/progenitor cells among a tissue or a mass of cells as constituted of a plurality of cell species, and a method for screening for a drug functioning as a nerve differentiation factor or the like by using the above-mentioned detection method. It was found in this invention that the expression of the NC1 gene was high in undifferentiated nerve stem cells and said expression decreased with an advance of differentiation. Furthermore in this invention, by using the NC1 gene, the product thereof (NC1 protein) and the base sequences or the amino acid sequences thereof, antibodies or the like, it became possible to detect nerve stem cells/progenitor cells by way of various methods, so that a novel method for screening for a drug functioning as a nerve differentiation factor or the like was provided.
