Abstract

Official abstract text for this publication.

The present invention relates to a method for controlling differentiation of pluripotent stem cells, which method comprises selecting a laminin or a fragment thereof based on binding affinity for the pluripotent stem cells and inducing differentiation of the pluripotent stem cells in the presence of the laminin or a fragment thereof. Here, the binding affinity for cells can be assessed by time-course observation of the survival rate and motility of the cells. According to the present invention, a cell population containing any desired proportion of differentiated cells can be produced from pluripotent stem cells in a simple manner. The cell population obtained by this production method is very useful for cell therapy-based treatment strategies for diseases.

First claim

Opening claim text (preview).

1 . A method for controlling differentiation of pluripotent stem cells toward corneal epithelial cells, the method comprising: inducing differentiation of the pluripotent stem cells in the presence of laminin 332 or a laminin 332E8 fragment, which directs differentiation toward corneal epithelial cells. 2 - 12 . (canceled) 13 . A method for controlling differentiation of pluripotent stem cells toward neural crest cells, the method comprising inducing differentiation of the pluripotent stem cells in the presence of laminin 211 or a laminin 211E8 fragment, which directs differentiation toward neural crest cells. 14 . A method for controlling differentiation of pluripotent stem cells toward retinal cells or neural crest cells, the method comprising inducing differentiation of the pluripotent stem cells in the presence of laminin 411 or a laminin 411E8 fragment, which directs differentiation toward retinal cells or neural crest cells. 15 . A method for producing an eye-related cell population, comprising culturing differentiated cells derived from pluripotent stem cells by the method according to claim 1 . 16 . The method according to claim 15 , wherein the cell population to be produced is a corneal epithelial cell population. 17 . A method for fabricating a corneal epithelial cell sheet for transplantation using a corneal epithelial cell population produced by the method according to claim 16 . 18 . A method for producing an eye-related cell population, comprising culturing differentiated cells derived from pluripotent stem cells by the method according to claim 13 . 19 . A method for producing an eye-related cell population, comprising culturing differentiated cells derived from pluripotent stem cells by the method according to claim 14 .
