| 41. | Four embryonic stem cell lines from human fetal somatic cells were derived from those blastocysts.
|
| 42. | Monozygotic twinning is not increased after blastocyst transfer compared with cleavage-stage embryo transfer.
|
| 43. | Pre-implantation blastocyst development is a controlled cascade of gene regulation and intercellular signaling.
|
| 44. | One cell type endures the knockout and is put into a blastocyst of another type.
|
| 45. | WWC2 expression is found to be elevated in the blastocyst and fetal stages of development.
|
| 46. | The blastocyst is then implanted in the mother's uterus and the pregnancy proceeds normally.
|
| 47. | Because the cells grow and divide indefinitely in culture, very few blastocysts would be needed.
|
| 48. | Before leaving Worcester, I ask Cibelli when he will know if any blastocysts have formed.
|
| 49. | Sixteen blastocysts survived the biopsy ( the removal of one or two cells for screening ).
|
| 50. | That means that in principle the cells from just a single blastocyst could satisfy all requirements.
