Abstract: The present disclosure provides a surface-treated aluminum material having excellent adhesiveness to resins, on the surface of which an oxide film is formed, the oxide film comprising a surface-side porous aluminum oxide film having a thickness of 20 to 500 nm and a base-side barrier aluminum oxide film having a thickness of 3 to 30 nm, wherein small pores each having a diameter of 5 to 30 nm are formed on the porous aluminum oxide film, and the length of cracks formed in a boundary between the porous aluminum oxide film and the barrier aluminum oxide film is not more than 50% of the length of the boundary, a method for manufacturing the surface-treated aluminum material, and a surface-treated aluminum material-resin bonded body, comprising the surface-treated aluminum material and a resin that covers the surface of the oxide film formed thereon.

Abstract: There are provided: a surface-treated aluminum material including an aluminum base material and an alkali alternating current electrolytic oxide coating film formed on at least a part of a surface of the aluminum base material, wherein the alkali alternating current electrolytic oxide coating film includes a porous-type aluminum oxide coating film layer formed on a surface side and a barrier-type aluminum oxide coating film layer formed on a base material side, and plural working grooves perpendicular to the direction of plastic working are formed; a method of producing the surface-treated aluminum material; a bonded body of the surface-treated aluminum material and a member to be bonded, including the surface-treated aluminum material and the member to be bonded, such as resin; and a method of producing the bonded body.

Abstract: A laminate comprising a transparent collagen I type sheet and a human corneal endothelial cell culture layer provided on the sheet. An endothelial cell culture layer laminate usable in transplantation is provided.

Abstract: Providing is cellular aggregates derived from corneal endothelial cells that, when transplanted, readily adhere to the parenchyma of cornea and function in a manner equivalent to corneal endothelial cells, and a method of transplantation of the cellular aggregates. Cellular aggregates derived from corneal endothelial cells. The cellular aggregates derived from corneal endothelial cells is prepared by culturing human corneal endothelial cells in a medium containing fetal bovine serum, growth factor and glucose; and then float culturing the cells obtained in a medium containing growth factor. A method of transplantation into the anterior chamber the cellular aggregate or the cellular aggregate prepared by the above method, comprising inserting a tube into the parenchyma of cornea, introducing the cellular aggregate into the anterior chamber through the inserted tube, and causing the cellular aggregate that has been introduced to adhere to Descemet's membrane by assuming in a downward-facing position.
