We would certainly hope that our patented, proprietary 'embryo-safe' single-cell blastomere technique would be a part of any such conversation.
This process is described in footnote 3, supra; it raises special considerations because of the inherent capacity for reproductive cloning if ES cells are derived from the cells that divide first (the blastomere stage).
2000) found that nearly 45% of thawed embryos suffered some amount of blastomere (cell) loss, causing an approximate 30% reduction in implantation.
193) The eggs are fertilized in a lab, and then the pre-embryos gestate to the blastomere stage--eight cells.

Embryo grading (modified from Veeck (3)) was utilised to determine the embryo quality (morphology) on a scale of 1 - 5 (5 being best) and included blastomere number, blastomere regularity and size and blastomere fragmentation.
They see no objection to using the blastomeres in this way: they understand the mechanical processes of fertilization and DNA incorporation, and find it incredible that such processes confer on the zygote some distinctive status; they know that the blastomere is formed a major embryonic stage before the pre-pattern of the central nervous system is laid down, and that, in consequence, there isn't even the ghost of a sentient organism present.
Multiple blastomere biopsies were obtained from each embryo to minimize the number of embryos used in this study," according to another sentence added in the November Nature.
