Apparatus and method for manufacturing channel-coupled scaffold
The present disclosure relates to an apparatus and a method for manufacturing a channel-coupled scaffold. The present disclosure provides a method for manufacturing a channel-coupled scaffold, which includes: (1) a step of compressing a first elastic substrate which includes a groove on the surface of the substrate to close the groove; (2) a step of loading a scaffold composition onto the closed groove; and (3) a step of restoring the elastic substrate. The present disclosure also provides an apparatus for manufacturing a channel-coupled scaffold, which includes: a first elastic substrate which includes a groove on the surface of the substrate and onto which a scaffold composition is loaded: and a compression module which compresses the width of the groove of the elastic substrate to close it. The apparatus or method may accumulate a microchannel controlling local mass transfer, and align a collagen fiber in the scaffold at the same time.
METHOD AND CONTAINER FOR PRESERVING CORNEAL ENDOTHELIAL CELLS
The present disclosure provides a method of preserving corneal endothelial cells at a high cell survival rate. The present disclosure provides a method of preserving corneal endothelial cells and/or corneal endothelium-like cells, comprising preserving the corneal endothelial cells and corneal endothelium-like cells in a container with a bottom area of at least about 0.7 cm.sup.2. Accordingly to the present invention, corneal endothelial cells can be preserved at a high cell survival rate. Corneal endothelial cells preserved in this manner have functions of normal corneal endothelial cells. Such cells can also be used as cells for treating a corneal endothelial disease or the like.
INJECTION MOLDING TO GENERATE COMPLEX HYDROGEL GEOMETRIES FOR CELL ENCAPSULATION
Provided herein is a cell macroencapsulation device composed of hydrogel in a 3D conformation that optimizes encapsulated cell viability and function when transplanted into a vascularized tissue space. The hydrogel macroencapsulation device is intended to reduce or eliminate immune response to the cell graft, while allowing exchange of encapsulated cell-secreted products, such as insulin. Also described herein is an injection-mold and fabrication process to generate the hydrogel macroencapsulation devices for use in the clinic.
Cell culturing method and kit
The present invention relates to a cell culturing method and kit. More specifically, it relates to a cell culturing method and kit using a support that is exposed to the air. It further relates to a method of culturing cells by allowing them to migrate onto a porous polyimide film.
Systems and methods for immobilizing extracellular matrix material on organ on chip, multilayer microfluidics microdevices, and three-dimensional cell culture systems
The presently disclosed subject matter provides an approach to address the needs for microscale control in shaping the spacial geometry and microarchitecture of 3D collagen hydrogels. For example, the disclosed subject matter provides for compositions, methods, and systems employing N-sulfosuccinimidyl-6-(4′-azido-2′-nitro-phenylamino)hexanoate (“sulfo-SANPAH”), to prevent detachment of the hydrogel from the anchoring substrate due to cell-mediated contraction.
METHODS OF MAKING IMPROVED HUMAN INTESTINAL ORGANOID COMPOSITIONS VIA APPLICATION OF STRAIN AND HUMAN INTESTINAL ORGANOID COMPOSITIONS THEREOF
Disclosed herein are methods of enhancing development of a three-dimensional in vitro model of an intestinal tissue (HIO), which may be derived from a precursor cell. The precursor cell may be, for example, an embryonic stem cell, an induced pluripotent stem cell (iPSC), or the like. The in vitro HIO model may be characterized in that the HIO has a lumen, in which a lengthening device may be inserted to promote development of the HIO. Compositions derived from the disclosed methods are also described.
Bi-layer multi-well cell culture platform
The methods and systems described herein provide a cell culture platform with an array of tissue modeling environments and dynamic control of fluid flow. The cell culture platform includes an array of wells that are fluidically coupled by microchannel structures. The dynamically controlled flow of fluid interacts with cells grown within the microchannels.
CELL CULTURE SHEET
The present invention provides a cell culture sheet comprising a plurality of recesses each having an opening of 1000 μm or less in diameter, wherein each recess has an inner circumferential face and a bottom face, wherein the inner circumferential face has a non-cell adhesive surface, and wherein the bottom face has a cell-adhesive surface; and a method for producing a cell culture sheet, the method comprising laminating of a layer having a non-cell adhesive surface and a layer having a cell-adhesive surface, wherein the layer having a non-cell adhesive surface has a plurality of through-holes of 1000 μm or less in diameter. The cell culture sheet of the present invention can be prepared simply and assists efficient cell culture operation, and therefore can preferably be used in the field of cell-based pharmaceutical preparations, for example, spheroid-containing pharmaceutical preparations etc.
Patterned electrospun fibers for tissue engineering
A composition of matter for tissue engineering is disclosed. The composition comprises a plurality of electrospun albumin fibers, wherein an outer surface of the composition comprises a pattern of ridges or indentations, wherein the ridges or indentations are wider than the diameter of a single electrospun albumin fiber of the plurality of electrospun albumin fibers.
CULTURE CONTAINER BASE MATERIAL, CULTURE CONTAINER, AND PRODUCTION METHOD OF CULTURE CONTAINER BASE MATERIAL
Provided is a culture container base material made of a polyolefin material, capable of readily forming a culture container for culturing adherent cells. The culture container base material is for culturing the adherent cells and made of the polyolefin material. At least a part of a surface of the base material is subjected to a surface treatment, where the surface of the base material is a culture surface of the culture container, and the surface subjected to the surface treatment has a static water contact angle of greater than 80° and a receding contact angle of less than 53°.
