    摘要: The invention relates to methods of introducing a heterologous DNA sequence into a mouse embryonic stem cell wherein the DNA sequence is inserted by homologous recombination into a villin gene/I-SceI hybrid by creating a double strand break with I-SceI meganuclease. Subsequently, the mouse embryonic stem cells can be used to generate a transgenic mouse comprising the heterologous DNA sequence. Additionally, the methods can be used for gene replacement in ovo where a mouse oocyte containing a villin gene/I-SceI hybrid within its genome exists or is first generated. More generally, the methods can be used for the targeted insertion of a heterologous DNA sequence into any cell containing a villin gene/I-SceI hybrid sequence within its genome.
