Screening method for somatic cell nuclear reprogramming substances

摘要

(A) a step of contacting a test substance with a somatic cell containing a gene in which a marker gene is present at a position that is subject to expression regulation by the expression regulatory region of the ECAT gene; and (b) after the step (a), The present invention provides a screening method for a somatic cell nuclear reprogramming substance, including the step of examining the presence or absence of the appearance of a marker gene-expressing cell and selecting a test substance that has caused the cell to appear as a somatic cell nuclear reprogramming candidate substance. .
