WebTransgenic embryos produced by pronuclear injection showed a discrete pattern of GFP expression with clusters at 25, 50, and 100% of blastomeres expressing GFP. This pattern of mosaicism is interpreted to indicate that the integration of microinjected DNA occurred, not only at the pronuclear stage, but also in the subsequent cell divisions.
