摘要:
A main object of the invention is to provide a new method for producing a cell culture substrate used to cause cells to adhere in a highly precise form onto a base material and then culture the cells. To attain the object, the invention provides a method for producing a cell culture substrate comprising: a patterning substrate forming process of forming, on a base material, a cell culture patterning layer wherein a cell adhesion portion having cell adhesive properties and a cell adhesion-inhibiting portion having cell adhesion-inhibiting properties can be formed by action of a photocatalyst by energy irradiation, thereby forming a patterning substrate; an energy irradiating process of irradiating the energy onto the cell culture patterning layer, thereby forming the cell adhesion portion and the cell adhesion-inhibiting portion in a pattern form by action of the photocatalyst; and a cell-containing liquid applying process of applying a cell-containing liquid onto the cell adhesion portion by a region-selecting applying method of applying the cell-containing liquid selectively onto the patterned cell adhesion portion.

A method for producing a cell culture substrate to which cells adhere in a finely processed pattern while retaining the pattern for a long period of time to culture the cells and a production apparatus used in the production method. The method includes: forming a patterning substrate by forming: on a base material, a light shielding portion, and a cell adhesive layer having adhesion to a cell and containing a cell adhesive material which is decomposed or denatured by an action of a photocatalyst upon energy irradiation so as to cover the light shielding portion; an energy irradiating process of irradiating energy to the patterning substrate from the base material side to form a pattern; and a cell adhesion process of making the cell adhere to the cell adhesion portion in a cell culture medium containing the cell and a culture medium.

The isomerization catalyst is a solid acid catalyst formed with a base of tungstated zirconium mixed oxides loaded with at least one hydrogenation/dehydrogenation metal catalyst from Groups 8-10 (IUPAC, 2006) and impregnated with at least one alkali metal from Group 1 (IUPAC, 2006). The metal from Groups 8-10 is preferably selected from platinum, palladium, ruthenium, rhodium, iridium, osmium and mixtures thereof, and most preferably is platinum. The Group I alkali metal is selected from lithium, sodium, potassium rubidium and cesium and mixtures thereof, and is preferably lithium, sodium, or potassium. Preferable, the catalyst forms, by weight, a base having between about 80-90% zirconium mixed oxides and between about 10-20% tungstate; between about 0.1-3.00% Group 8-10 metal; and between about 0.01-1.00% Group 1 alkali metal.
