Non-injection methods for the production of embryonic stem cell-embryo chimaeras

Nature. 1993 Sep 2;365(6441):87-9. doi: 10.1038/365087a0.


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.
