If however, the 'it' refers to the phenotypic and epigenetic state of the derived morula blastomeres, then the sentence would make sense.
Survival of cryopreservation and thawing with all blastomeres intact identifies multicell embryos with superior frozen embryo transfer outcome.
We believe that ACT is well positioned regardless of this ruling, as the court's pronouncement on what constitutes embryonic stem cell research that cannot be federally funded does not include ES cells derived by ACT's Blastomere technology as those cells can be generated without destruction of the embryo.
This finding suggests that single gene defects might be treatable through the transplantation of normal blastomeres containing the missing or defective gene.
Effect of blastomere loss on the outcome of frozen embryo replacement cycles.
Lanza's logic is that if prospective parents contemplating PGD can still get the benefit of genetic analysis, they would not object if the blastomere removed for genetic analysis also gives rise to stem cells, and especially not if it gives their future offspring the chance to have matched stem cell lines for potential future therapeutic use.
Female mice receiving oral administration of the insecticide lindane either before or immediately after mating increased blastomere lysis and suppressed cell proliferation of two-cell embryos and morulae (Scascitelli and Pacchierotti 2003).
In the most contested cases, such as creating embryos for research or transferring embryos produced by blastomere separation, there is no clear right answer precisely because of the symbolic nature of the dispute.
The downside of using FISH is that it is applied at the blastomere stage, which does not represent the rest of the embryo and is susceptible to chromosomal mosaicism in embryos during cell division, which can lead to the transfer of abnormal embryos.
Because each blastomere at this stage is in theory totipotent (that is, capable of producing an entire organism itself), die separated cells can become new embryos, all of which which have the same genome.
The National Institutes of Health (NIH) recently proposed broadening the definition of a human embryonic stem cell to include ACT's "single blastomere technology platform" which was used to derive ACT's MA09-hRPE cells.
PCR is a rapid, easy procedure for large scale sexing, and primers derived from many Y-specific sequences have been used to screen blood, meat and blastomere samples (Zeleny et al.
