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

摘要

It is an object of the present invention to provide a method for selecting cells capable of differentiating germ cells by employing expression of marker genes as an indicator in a simple manner without complicated operations such as homologous recombination. The present invention provides a method for obtaining germ cells which comprises recovering cells capable of differentiating germ cells from a transgenic non-human mammalian animal into which a recombinant expression vector comprising a marker gene under the control of a promoter sequence of a mammalian-derived Vasa homolog gene has been introduced by employing expression of said marker gene as an indicator.
