    摘要： A diseased site where an anterior segment tissue is partly or entirely damaged or deficient can be treated using a corneal epithelium forming cell sheet that will adhere well to the anterior segment tissue. To attain this objective, a corneal epithelium forming cell sheet is produced by a process comprising the steps of cultivating under specified conditions corneal epithelium forming cells on a cell culture support comprising a substrate having its surface covered with a temperature responsive polymer of which the hydrating force varies in a temperature range of 0° C.-80° C., optionally stratifying the layer of cultured cells, and thereafter, (1) adjusting the temperature of the culture solution to either above an upper critical dissolution temperature or below a lower critical dissolution temperature, (2) bringing the cultured corneal epithelium forming cells into close contact with a carrier, and (3) detaching the sheet together with the carrier under specified conditions.

    摘要： The present invention provides a collagen crosslinking agent superior in biocompatibility that is free from the damage by UV irradiation and also from the problems of toxicity caused by residual monomer or unreacted functional groups. Provided is a noncovalent collagen crosslinking agent (for fibrous protein collagen), comprising a spacer of a polyvalent alcohol having two or more OH groups at the terminals and arms of collagen peptides formed of repetitions of three amino acids, the arms being bound via the OH groups to the spacer.

    摘要： The present invention relates to a method for preparing corneal endothelial progenitor cells by adherent culturing a cell population isolated from corneal endothelial cell tissue at a low density by using a serum-free medium. The present invention also relates to a method for preparing corneal endothelial cells by differentiation-inducing the corneal endothelial progenitor cells obtained by the aforementioned method. According to the present invention, corneal endothelial progenitor cells can be selectively grown from a corneal tissue-derived cell population, and corneal endothelial cells obtained by inducing the corneal endothelial progenitor cells can be applied to treatment of corneal endothelial diseases. As a result, problems of corneal transplantation such as shortage of donors and occurrence of rejection can be solved.
