Experimental models of blastocyst development based on in vitro culture have played a prominent role in advancing our understanding of peri-implantation development, a process that is relatively inaccessible in vivo. Blastocyst culture provides a robust approach for examining embryonic interactions with the microenvironment under highly controlled ...

The Biology of the Blastocyst [PDF]
JAMA: The Journal of the American Medical Association, 1971 Dr. Blandau presents an outstanding text in reproductive biology, dealing with the mammalian blastocyst. At the 1969 Lake Wilderness conference, he and other notable scientists worked toward a better understanding of the complex embryo-uterine interrelationships as well as a new prospective on contraception.

Parthenogenetic Mouse Blastocysts
Nature, 1970A READY supply of parthenogenetic mammalian embryos would be useful. Parthenogenones which develop from unfertilized eggs may be haploid, diploid or polyploid, depending on whether the meiotic divisions and first cleavage division occur1. Haploid cells can be used for studying cellular genetics and embryology.

The human oocyte is surrounded by the zona pellucida—an elastic, transparent extracellular matrix consisting of specific glycoproteins. The zona pellucida is preserved after fertilization and surrounds the developing human embryo for a few days. The embryo needs to get out of the zona pellucida before implantation to establish cell contacts between the

To date preimplantation diagnosis has been made in the two-eight cells embryos because these are available in IVF programs. However, most patients referred for IVF are infertile, very few undergoing IVF with the thought of preimplantation diagnosis.

Cryopreservation of Blastocysts
2001Based on observations collected from IVM-IVF bovine blastocysts, we developed and modified cryopreservation programs for human co-cultured blastocysts. We have used glycerol as cryoprotectant, and sucrose. We were surprised to observe that the in vitro grown blastocysts are rather more sensitive to high concentrations of cryoprotectants.
