A method for producing a tooth having a desired length in one direction includes the steps of: placing a first cell aggregate and a second cell aggregate in the inside of a support while bringing the first and the second cell aggregates into close contact with each other; and culturing the first and the second cell aggregates in the inside of the support, in which the first cell aggregate is composed of one of mesenchymal cells or epithelial cells and the second cell aggregate is composed of the other, and the size of the tooth is controlled by adjusting the length of contact between the first cell aggregate and the second cell aggregate in one direction.

Method for producing tooth

Disclosed are a perfusion culture method and a perfusion culture device whereby a perfusate can be delivered to all parts of an organ or tissue so that the organ or tissue can be preserved while sufficiently maintaining the function thereof. Specifically disclosed is a method for perfusion culture of an organ or tissue removed from a mammal, said organ or tissue having been removed together with a second organ or tissue connected to the aforesaid organ or tissue in vivo, which comprises a step for fixing said second organ or tissue so as to hang the aforesaid organ or tissue and a step for perfusing blood vessels in the aforesaid organ or tissue with a perfusate.

Perfusion culture method and perfusion culture device for organ or tissue

A first cell mass substantially containing only either one of mesenchymal cells or epithelial cells and a second cell mass substantially containing only the other one of the cells are positioned in contact with each other inside a support carrier which can maintain a condition of cell contact; and cultured to obtain a tooth having a specific cell placement. Preferably, after the culturing, the support carrier having both cell masses is cultured with kidney cells.

Method of producing tooth, set of teeth, and method of producing tissue

A digital prepress system capable of preparing an excellent proof sheet free from the wrong conversion of characters and double procedure of trapping processing, having little color difference of images between the proof sheet and the regular printed matters and imparting no impression that proofreading paper and regular printing paper are different in the color tone, feeling of gloss and the like. This invention provides a digital prepress system wherein digital data are processed on a unit of Raster image processor and data obtained therefrom are transferred to a planographic print output unit and an ink jet printer to generate a planographic print and a proof sheet respectively, said ink jet printer includes a device for preparing said proof sheet to make ink jet recording on a proofreading paper having a color difference of 2 or less and a gloss difference of 75&deg; specular gloss in an absolute value of 15 or less as compared with regular printing paper according to the provisions of JIS 28730, with the basis weight different from that of regular printing paper by a range between &minus;10 to &plus;50%.

Digital prepress system

Disclosed is a light-sensitive element for lithographic printing plates excellent in stain resistance and water-carrying capacity which comprises a support and, coated thereon in succession, at least one undercoat layer, a silver halide emulsion layer and a physical development nuclei layer wherein at least one of the layers on the silver halide emulsion layer-provided side of the support contains 0.1-2.0 g/m.sup.2 of a matting agent of 5.mu. in average particle size and the light-sensitive element has an arithmetical mean deviation of profile Ra of 1.2 or less.
