While multiple studies have shown that the pregnancy rate is slightly lower when replacing a single embryo, as compared to 2, the pregnancy rate is still very high in a selected patient population (< 35 with extra blastocysts to freeze).

Multiple pregnancy (twins, triplets, etc.) is associated with greatly increased risks of prematurity and very low birthweight, so the transfer of a single blastocyst in all patients was a vital improvement.

How can you have a meeting with people who come to it with a deep abiding faith that a fertilized egg is a person, and a blastocyst created by nuclear transfer is a person, and the destruction of that blastocyst to harvest stem cells is murder?

After reactivating the cells with an electric shock, the group grew several oocytes in culture to the blastocyst stage.

They found that some sperm DNA methylation regions were also associated with poor blastocyst stage of embryo quality as defined by the IVF clinic's standards related to embryo quality before transfer into the uterus of the female partner to establish a pregnancy, Pilsner says.

Twenty percent of the cells cloned in this way grew into early embryos, called blastocysts, and 5 percent of them yielded embryonic stem cells, which is comparable with results obtained from unfertilized eggs.

They then preserved the blastocysts and stained them with antibodies that make syncytin - 1 fluoresce.

The images depict what might be called embryology in flagrante: micrographs of sperm cells, trailing accordion - like pleats of white zags as they streak across a vast blue ocean of ooplasm; a multihued blastocyst in the process of hatching out of the egg's zona pellucida; and egg cells with a fringe of glowing, fate - determining proteins, looking a bit like a solar eclipse inside a cell.

His group began with 242 eggs, but after removing the eggs» nuclei and swapping in those of somatic cells, the investigators produced only 30 blastocysts (week - old embryos), from which they coaxed just one stem cell line into being.

No one has yet shown success with SCNT using human tissue: The closest effort so far has been the cloned blastocyst reported last year by workers at the Newcastle Fertility Centre in the U.K., but that did not yield ES cells.

Embryonic development in mammals begins with the division of the fertilized egg, which is then followed by several further rounds of division to form the blastocyst, a sphere of cells made up of two layers of cells surrounding a fluid - filled cavity.

Indeed, they needed to modify the previous techniques that had been used with abnormally fertilised eggs, in order to have good survival to blastocyst stages and to reduce carryover of mitochondria along with the pronuclei.

The authors demonstrated that an early pronuclear transfer (ePNT) yields better blastocyst survival in comparison with late pronuclear transfer.

Four out of five lines showed low level of heteroplasmy, whereas one derived from a blastocyst with around 4 % mtDNA carryover showed an upward drift of heteroplasmy and variation among hESC colonies at the passage 12.

When the studies of mitochondrial carryover were done in embryonic stem cells derived from ePNT blastocysts (to allow for more cell divisions during which instability could manifest), some stem cell lines displayed instability and an increase in mitochondrial DNA carryover with time.

When the somatic cells are initially reprogrammed with the 4 genes and then allowed to divide, do they go to a blastocyst - like stage in which cells are taken to generate and perpetuate the iPS, or is it something different from that?

Thomson's group used blastocysts from in vitro fertilization (IVF) clinics with full donor consent.

Approximately ten to fifteen iPS cells were injected into the cavity of each blastocyst, all of which were kept in KSOM with amino acids until embryo transfer.

Eight morulas and seven blastocysts were harvested after culturing in Quinn's Blastocyst media supplemented with 10 % SPS at 37 °C in 6 % CO2, 5 % O2 and 89 % N2.

Importantly, iPS cells extensively integrate with various host tissues and contribute to the germline when injected into the blastocysts.

Diploid blastocysts at 3.5 day post coitum (dpc) were collected from the uterus of superovulated ICR females mated with ICR males and kept in KSOM medium with amino acids until iPS cell injection.

Parthenogenic blastocysts exhibited mRNA expression profiles similar to those of blastocysts obtained after IVF / ICSI with the exception for MKLP2 and PEG1.

In our data analysis, we observed 97 % similarity in mRNA expression between parthenotes and IVF / ICSI embryos at the blastocyst stage (Figure 3 and 4B), with reduced similarity at the morula stage (83.6 %, Figure 3 and 4A).

By manipulating a specific gene in a mouse blastocyst — the structure that develops from a fertilized egg but is not yet an actual embryo — scientists with the University of Florida's McKnight Brain Institute and the Harvard Stem Cell Institute caused cells destined to build an embryo to instead change direction and build the cell mass that leads to the placenta.

That this occurs once cells enter differentiation, is consistent with a requirement for sustained FGF signalling for commitment and segregation of the PrEn lineage in cultured blastocysts [57].

Most notably, however, parthenogenic blastocysts were only produced from embryos cultured with supplementation and not with Sage or IVM - medium alone (Table 2 and Figure S2).

Thus the modest changes in gene expression that accompany basal level PrEn expression interfere with the capacity of these cells to actively contribute to blastocysts.

Interestingly, it has been reported that mice with a mutation in Kap1 were obese and had behavioral problems, and the lower expression of Kap1 that we have found in the blastocysts produced by IVC could also be related to the behavior problem reported in mice generated by IVC [43].

For the analysis of gene expression in blastocysts, total RNA was isolated and purified from three pools of 10 blastocysts produced in vivo or in vitro (KSOM supplemented with 10 % FCS or in the presence of 1 g / L BSA) using the RNeasy Micro Kit (Qiagen)[18].

The relative amount of mRNA of 11 genes related to epigenetic reprogramming and gene silencing was quantified in blastocysts produced in vivo or produced in vitro in KSOM media supplemented with FCS (suboptimal condition) or with BSA (optimal condition).

Differences between mRNA expression of several epigenetic regulatory genes analyzed on blastocysts produced in vivo and by in vitro culture with FCS or BSA supplementation.

Cells with normal karyotype were injected into blastocysts isolated from C57BL / 6 mice.
