preimplantation mouse embryo
The role of membrane sterols in the compaction and subsequent development of the preimplantation mouse embryo was studied by incubating embryos in 7-ketocholesterol and other oxygenated sterols. These sterols have been shown to inhibit sterol synthesis and deplete membranes of cholesterol in a variety of other cell types. Compaction and subsequent blastocyst formation were normal when embryos w...
متن کاملThe Effect Of Vero Cells on Preimplantation Mouse Embryo in Cultur Medium
SUMMARY To study the effect of vero cells on preimplantation mouse embryos two groups of experiment were carried out. In experiment 1, pronuclear stage mouse embryos were co-cultured with Vero cells in RPMI medium and were examined under microscope for 4 days with 24h interval. The results showed co-cultured group developed better compared to control (87% to 80%, P<0.05) although, the rate ...
متن کاملDNA synthesis in the preimplantation mouse embryo.
Strain PO preimplantation embryos were labelled with [H]thymidine. The incorporation of the label was studied by autoradiography of air-dried and serially sectioned embryos. DNA amounts were measured with a microdensitometer. The following observations were made at the 5to 16-cell stages. All nuclei contained 2C-4C amounts of DNA and all could eventually synthesize DNA. However, after short lab...
متن کاملLineage specification in the mouse preimplantation embryo.
During mouse preimplantation embryo development, totipotent blastomeres generate the first three cell lineages of the embryo: trophectoderm, epiblast and primitive endoderm. In recent years, studies have shown that this process appears to be regulated by differences in cell-cell interactions, gene expression and the microenvironment of individual cells, rather than the active partitioning of ma...
متن کاملThe Effect of Human Follicular Fluid (FF) on Preimplantation Mouse Embryo Development in Vitro
SUMMARY Since at oocyte retrieval for in vitro fertilization there is some FF become incorporate to egg, we decided to investigate the effect of this fluid on preimplantation embryo development in vitro. FF was obtained at the time of oocyte retrieval for IVF, centrifuged and then either inactivated by heat and stored at 4°c or without inactivation stored at-20°c until used. Late 2-cell emb...
