EXPRESSION VECTOR HAVING PROMOTER SEQUENCE OF VASA HOMOLOGUE GENE DERIVED FROM MAMMAL AND USE THEREOF

摘要

Disclosed is a method for screening a cell capable of differentiating into a germ cell in a simple manner by utilizing the expression of a marker gene as an indicator, which does not need any complicated operations such as homologous recombination. A method for producing a germ cell comprising the step of collecting a cell capable of differentiating into a germ cell from a transgenic non-human mammal having a recombinant expression vector introduced therein utilizing the expression of a marker gene as an indicator, the recombinant expression vector having the marker gene integrated therein such a manner that the marker gene is placed under the regulation of a promoter sequence of a Vasa homologue gene derived from a mammal.
