Exempel på hur man kan använda OOCYTES i en mening

• As women age, the number of ovarian follicles and oocytes (eggs) decline, leading to a reduced ovarian reserve.
• As women age, oocytes develop defects in mitochondrial structure and function and have meiotic spindle dysregulation: these increase rates of aneuploidy and miscarriage.
• Canine sperm can live for 10 to 11 days in the fallopian tubes so if a female is bred 10 days before the oocytes (ovum) can be fertilized, she will appear to have a gestation length of 70 days.
• With Robert William Briggs, he worked on transplantation of somatic cell nuclei from adult frogs into enucleated oocytes this leading to the first clone of an animal in 1952.
• Oogenesis results in the formation of both primary oocytes during fetal period, and of secondary oocytes after it as part of ovulation.
• Preimplantation genetic diagnosis (PGD or PIGD) is the genetic profiling of embryos prior to implantation (as a form of embryo profiling), and sometimes even of oocytes prior to fertilization.
• Because the entry of oocytes into meiosis is frequently referred to as oocyte maturation, this cytoplasmic factor was called maturation promoting factor (MPF).
• The zona pellucida (Latin meaning "transparent zone") is the specialized area surrounding mammalian oocytes (eggs).
• Cytochalasin B makes the cytoplasm of the oocytes more fluid and makes it possible to aspirate the nuclear genome of the oocyte within a small vesicle of plasma membrane into a micro-needle.
• Gurdon and colleagues also pioneered the use of Xenopus (genus of highly aquatic frog) eggs and oocytes to translate microinjected messenger RNA molecules, a technique which has been widely used to identify the proteins encoded and to study their function.
• Brief strontium chloride exposure induces parthenogenetic activation of oocytes which is used in developmental biological research.
• In the female germline before meiotic entry, X-inactivation is reversed, so that after meiosis all haploid oocytes contain a single active X chromosome.
• Thus, although the majority of oocytes are produced in female fetuses before birth, these pre-eggs remain arrested in the dictyate stage until puberty commences and the cells complete ootidogenesis.
• Prior to the production of Polly and Molly, the only demonstrated way to make a transgenic animal was by microinjection of DNA into the pronuclei of fertilized oocytes (eggs).
• fortunata features a standard process in which immature female gamete cells (oogonia) undergo mitosis to form oocytes.
• Glycerol and DMSO have been used for decades by cryobiologists to reduce ice formation in sperm, oocytes, and embryos that are cold-preserved in liquid nitrogen.
• During embryonic development, twins can form from the splitting of a single embryo (monozygotic) which forms identical twins or the twins can arise from separate oocytes in the same menstrual cycle (dizygotic) which forms fraternal twins.
• Homologous recombinational repair of DNA double-strand breaks mediated by BRCA1 and ATM weakens with age in oocytes of humans and other species.
• - A research team led by Mónica Bettencourt Dias shed light upon the critical mechanism of how oocytes, the maternal gametes, lose centrioles and the importance of doing so for female fertility.
• Vitellogenin (VTG or less popularly known as VG) (from Latin vitellus, yolk, and genero, I produce) is a precursor of egg yolk that transports protein and some lipid from the liver through the blood to the growing oocytes where it becomes part of the yolk.
