摘要:
It is an object of the present invention to provide a feeder cell with less variation in quality. The present invention relates to a feeder cell derived from a tissue stem and/or progenitor cell. A method of preparation of the feeder cell, a method of preparation of a cultured cell using the feeder cell, and a cell culturing kit are also provided.
摘要:
The present invention aims to provide a method of efficiently producing corneal endothelial cells, particularly from corneal stroma or iPS cell-derived neural crest stem cells, a method of producing corneal endothelial cells stably in a large amount by inducing more efficient differentiation of stem cells into corneal endothelial cells, and a medicament containing corneal endothelial cells. A method of inducing differentiation of stem cells into corneal endothelial cells, which includes a step of culturing the stem cells in a differentiation induction medium containing a GSK3 inhibitor (preferably a GSK3² inhibitor) and retinoic acid, preferably the differentiation induction medium further containing at least one kind selected from the group consisting of TGFb2, insulin and a ROCK inhibitor, and the like.
摘要:
Disclosed are a method for manufacturing a cell sheet, comprising culturing cells on a fibrin-coated surface of a substrate until the cells reach confluency, continuing the cultivation of the cells for a sufficient time period to cause the degradation of fibrin at the bottom of the cells, and detaching the cultured cells from the substrate surface in a sheet-like form to give a cell sheet; a substrate for cell sheet preparation, a surface of which is coated with fibrin; and a composition for use in coating with fibrin a surface of a substrate for cell sheet preparation, the composition comprising fibrinogen and thrombin. The invention enables to cell sheets to be manufactured by a simple manipulation using a substrate coated with a commercial, commonly available material of which safety has been confirmed.
摘要:
Using the medium of the present invention for inducing a cornea endothelial substitute cell from an iPS cell, the medium containing an insulin-like growth factor and a STAT3 activator, and not containing a basic fibroblast growth factor or a ROCK inhibitor, and the method of the present invention for inducing corneal endothelial substitute cells from iPS cells by using the medium, it becomes possible to efficiently produce corneal endothelial substitute cells, particularly to efficiently produce corneal endothelial substitute cells from iPS cells. Furthermore, it becomes possible to stably produce large amounts of corneal endothelial substitute cells by inducing differentiation of iPS cells into corneal endothelial substitute cells more efficiently.

摘要:
The present invention provides: a novel metalloprotein, i.e., selenium-lactoferrin; and a process for producing the metalloprotein. Selenium-lactoferrin according to the present invention can be produced suitably by adding a selenium salt to a solution containing lactoferrin and/or apolactoferrin and then subjecting the resultant mixed solution to dialysis or ultrafiltration. Selenium-lactoferrin according to the present invention has an excellent therapeutic effect on corneal and conjunctival diseases, and is suitable for mass production on an industrial scale.
