IN VITRO DIFFERENTIATION/INDUCTION OF LYMPHOCYTE FROM STEM CELL HAVING GENOTYPE PROVIDED AFTER GENE RECONSTITUTION

摘要

The present invention provides a production method of a functional differentiated cell having a post-rearrangement genotype of a particular antigen receptor gene, which includes culturing a stem cell having the genotype in a medium to give the differentiated cell derived from the stem cell. As the stem cell having the genotype, a stem cell (e.g., ES cell) established by transplantation of the nucleus of a cell having the genotype is preferable. As the differentiated cell, NKT cell is preferable.
