Abstract: A computer-readable recording medium storing therein a program for causing a computer to execute a process including: obtaining constraint conditions forming a 0-1 integer programming problem including variables each taking a value 0 or 1, each constraint condition including at least one of the variables; identifying pairings of a variable appearing only in a predetermined number of constraint conditions and the constraint conditions where the variable appears, the predetermined number being less than a total number of the constraint conditions; registering, in a storage unit, for each of the identified pairings, first correlation information correlating the variable of the pairing with another variable appearing in at least one of the constraint conditions of the pairing; registering, in the storage unit, second correlation information correlating, based on a degree of relationship between the variables, at least one of the variables and another variable having at least a predetermined degree of relationship with the at least one variable; and searching for a solution to the 0-1 integer programming problem by determining, based on the first and second correlation information, a group of any two or more correlated variables, for value inversion.

Abstract: The present invention relates to a method for inducing the differentiation of corneal epithelial cells from pluripotent stem cells. More specifically, the present invention relates to a method for autonomously differentiating pluripotent stem cells, such as human iPS cells, into ectodermal cell lineage in a serum-free medium without using feeder cells and inducing the differentiation of the resultant ocular surface ectodermal lineage cells into corneal epithelial cells.
