title: Non-injection methods for the production of embryonic stem cell-embryo chimaeras.
abstract: The simple aggregation of pluripotent ES cells with morulae-stage embryos can result in viable chimaeras at a similar frequency to that of blastocyst injection. The savings in time and equipment inherent in the aggregation techniques, however, make this approach well worth considering.
