A method for producing a stem cell having a mutation in both chains of alleles which comprises: A) the step of providing a stem cell; B) the step of preventing Blm alleles from functioning in the stem cell; and C) the step of inducing mutation in the stem cell. It is also intended to provide a library of stem cells having a mutation in both chains of alleles wherein stem cells involved in the library have the mutation transferred thereinto over the entire genome. | 12-25-2008 |
