[Problem] To provide a method for producing human corneal epithelial sheet, wherein the human corneal epithelial-derived cells obtained by culturing human corneal epithelial cells are cultured on an amnion substrate. [Solution] A method for culturing human corneal epithelial cells using mesenchymal stem cells as the feeder cells; and a method for culturing human corneal epithelial cells using a medium containing a ROCK inhibitor, a phosphodiesterase inhibitor, a MAP kinase inhibitor and a TGF-&#x3b2; receptor inhibitor in various combinations.

[Problem] To provide, in order to manufacture cells to transplant into patients with corneal endothelial failure, a medium used to culture corneal endothelial cells obtained from human corneal tissue and grow said cells while maintaining the morphology thereof as corneal endothelial cells. [Solution] A medium containing a conditioned medium from mesenchymal stem cells; and a method in which said medium is used to culture corneal endothelial cells.

Medium, for culturing corneal endothelial cells, containing conditioned medium from mesenchymal stem cells

Disclosed is a method for producing pluripotent stem cell-enriched human dental pulp-derived cells. The method is characterized in that it includes (a) culturing a dental pulp suspension in a feeder cells-culture vessel containing feeder cells whose proliferative ability is suppressed, on a membrane having micropores that can block passage of the feeder cells and supported in the feeder cells-culture vessel in a manner to prevent the lower side face thereof from contacting with the feeder cells, thereby preventing direct contact with the feeder cells, and, (b) a step for recovering the cells proliferating on the membrane.

Disclosed are a method for producing a frozen pharmaceutical composition prepared from cultured human mesenchymal stem cells and a pharmaceutical composition containing human mesenchymal stem cells. This method is a method for producing a frozen pharmaceutical composition containing human mesenchymal stem cells, which comprises the following steps in this order: (a) adding trypsin to human mesenchymal stem cells in a culture vessel to detach the cells from the surface of the culture vessel; (b) adding a bicarbonate Ringer's solution containing human serum albumin to the detached cells to terminate the reaction with trypsin, and washing the cells with the bicarbonate Ringer's solution containing human serum albumin; (c) suspending the cells in a bicarbonate Ringer's solution containing human serum albumin and dimethyl sulfoxide; (d) putting the resulting suspension in a container which allows freezing of what is contained therein, and sealing the container; and (e) freezing the suspension put in the container.
