Abstract:
A microchannel device includes: a channel unit which is configured of a plurality of channel members which are laminated in a thickness direction to define a microchannel, at least one of the channel members being made of a material having elasticity; and a holding member which is provided separately from or integrally with the channel unit and holds the channel unit in a state of being compressed in the thickness direction.
Abstract:
A protrusion/recess structure in which fine particles will not drop easily and which will not be deformed easily is provided, and a producing method for the same is provided. In the protrusion/recess structure (porous film), protrusions or recesses (fine corrugations) are formed in a surface. The protrusion/recess structure is formed from plural fine particles and an amphipathic high molecular compound having a catechol group. The high molecular compound at least partially coats a surface of the fine particles, to adhere the fine particles to one another. A diameter of the recesses is larger than a diameter of the fine particles. Cast film is formed from solution containing the fine particles and the high molecular compound having the catechol group. Condensation on the cast film is performed, and organic solvent and water droplets created by the condensation are evaporated to produce the protrusion/recess structure.
Abstract:
A composite film comprises a drug sustained-release portion and an adhesive portion which are layered on each other. The drug sustained-release portion has film-like drug layers and a film-like biodegradable polymer layer. The drug sustained-release portion has the drug layer, the biodegradable polymer layer, and the drug layer in this order from the adhesive portion side. Each drug layer is a drug form containing a drug of a predetermined concentration or more. The drug is released from the drug layer exposed. When the drug layer disappears, a biodegradable polymer of the biodegradable polymer layer starts to degrade and/or dissolve. When the biodegradable polymer layer disappears, the drug is released from the drug layer adjoining the adhesive portion. A plurality of pores are formed in the adhesive portion. The pores retain water due to capillary force.
Abstract:
Provided are a method for producing a hepatocyte culture and a method for improving or maintaining a function of a hepatocyte or a hepatic progenitor cell, each method including a culturing step of culturing a hepatocyte or a hepatic progenitor cell inside at least a part of a plurality of opening pores and communication pores of a porous film having the plurality of opening pores provided on a surface thereof and the communication pores for communicating the opening pores adjacent to each other; and a cell-containing porous film.
Abstract:
Provided is a microchannel device including a first microchannel that is formed in a first channel member, a second microchannel that is formed in a second channel member and at least a portion of which overlaps the first microchannel in plan view with a step portion formed between the first microchannel and the second microchannel, a porous membrane that has a plurality of holes penetrating the porous membrane in a thickness direction and is disposed between the first channel member and the second channel member to partition the first microchannel and the second microchannel, and a reinforcing member that is provided between the first channel member or the second channel member and the porous membrane, is higher in stiffness than the porous membrane, and reinforces at least a portion of the porous membrane that faces the step portion.
Abstract:
A living tissue model device includes: a first liquid compartment storing a liquid composition; a second liquid compartment storing a liquid composition; and a cell layered body disposed between the first liquid compartment and the second liquid compartment, as a partition between both compartments. A vascular wall model includes: a porous membrane having a honeycomb structure; a vascular endothelial cell layer disposed on one face of the porous membrane; and a smooth muscle cell layer, or a mesenchymal stem cell layer, disposed on another face of the porous membrane. A vascular wall model device includes: a first liquid compartment storing a liquid composition; a second liquid compartment storing a liquid composition; and a vascular wall model disposed between the first liquid compartment and the second liquid compartment, as a partition between both compartments. Applications of these models or model devices are also provided.
Abstract:
Provided is a composite binder material, a cell aggregate, a cell accumulation method, a cell preservation method, and a method of manufacturing a composite binder that can supply oxygen and nutrients to cells.A composite binder material comprises a binder material and a cell non-adhesive portion. A binder material formed in a membrane shape is provided between a first cell sheet and a second cell sheet. The cell non-adhesive portion formed at least in a portion of one membrane surface and/or other membrane surface of the binder material. A plurality of pores are formed in the binder material, and the pores open to the one membrane surface coming into contact with one sheet surface of the first cell sheet. The pores penetrate in a thickness direction and a surface direction along the one membrane surface. The porosity of the binder material is set to be at least 50%.
Abstract:
Provided are a lubricating material which is made of a non-fluorine-based compound and thus has a surface that is slippery enough for liquid such as water or oil, a lubricant-holding base material which holds a fluorine-based lubricant and thus can be used as a lubricating material, and methods for producing the same. A slippery film has a holding base and a lubricant. The holding base has pillar structure portions and fluorine-containing portions, and the fluorine-containing portions are provided on outer surfaces of a plurality of pillar portions in the pillar structure portion. The lubricant is a fluorine-based liquid, and the fluorine-containing portion has a C—F bond. The lubricant is loaded into a region surrounded by a plurality of the pillar portions and is held in this region.
Abstract:
Disclosed is a film which is able to suppress agglutination by being continuously adhered to an adhesion target portion in a biological body while suppressing a position shift. A film includes an adhesive and an adhesion inhibiting layer. The adhesive layer absorbs and maintains a liquid in a plurality of pores which are opened in one film surface and has a capillary force for adhering the adhesive layer to a first-cell group. The adhesive layer is formed of a biodegradable polymer. The adhesion inhibiting layer configures the other film surface, and inhibits adhesion between a second-cell group which is different from the first-cell group and the adhesive layer. In the adhesive layer, the pore is formed not to be penetrated in a thickness direction of the film, and thus the first-cell group and the second-cell group are separated into the one film surface side and the other film surface side.
