The oocytes of B6.Y(TIR) sex-reversed female mouse mature in culture but fail to develop after fertilization because of their cytoplasmic defects. To identify the defective components, we compared the gene expression profiles between the fully-grown oocytes of B6.Y(TIR) (XY) females and those of their XX littermates by cDNA microarray. 173 genes were found(More)
STUDY QUESTION How does l-carnitine (LC) supplementation during vitrification and in vitro maturation (IVM) of germinal vesicle stage (GV)-oocytes improve the developmental competence of the resultant metaphase II (MII) oocytes? SUMMARY ANSWER LC supplementation during both vitrification of GV-oocytes and their subsequent IVM improved nuclear maturation(More)
Oocyte cryopreservation is important for assisted reproductive technologies (ART). Although cryopreservation of metaphase II (MII) oocytes has been successfully used, MII oocytes are vulnerable to the damage inflicted by the freezing procedure. Cryopreservation of germinal vesicle stage oocytes (GV-oocytes) is an alternative choice; however, blastocyst(More)
To perform safe and successful corneal refractive surgery on myopic patients, corneal thickness (CT) and corneal epithelial thickness (CET) must be accurately measured. Numerous individuals with myopia wear soft contact lenses (SCLs) for the correction of visual acuity but may subsequently undergo corneal refractive surgery. The aim of the present study was(More)
The oocyte becomes competent for embryonic development by involving mutual communication with cumulus cells (CCs) during folliculogenesis. How this communication takes place under physiological conditions is not fully understood. Current study examined oocyte-CCs communication in the XY sex-revered female mouse. We have previously found that the XY oocyte(More)
The histone deacetylase inhibitor (HDACi) and tumor suppressor play an important role in genome reorganization and epigenetic regulation. In this study, granulosa cells (GCs) isolated from sika deer ovaries were cultured and treated with different concentrations of trichostatin A (TSA) for 48 h. It was found that TSA inhibited GCs proliferation and induced(More)
Efforts to increase mink reproductive success (live births and litter sizes) can be partly assessed by measurement of blood progesterone levels. However, the stress of blood sampling increases the incidence of failed matings, aborted fetuses and death of the dam. We have therefore non-invasively measured fecal progesterone metabolite (progestin)(More)
Early preimplantation embryos are extremely sensitive to dysregulation of cell volume, which can lead to developmental arrest. It was previously shown that mouse embryos at the two-cell stage respond to a cell volume decrease by quickly activating Na+/H+ exchange via a signaling mechanism that involves the tyrosine kinase Janus kinase 2 (JAK2). However, it(More)
Evaporative drying (ED) is an alternative technique for long-term preservation of mammalian sperm, which does not require liquid nitrogen or freeze-drying equipment, but offers advantages for storage and shipping at ambient temperature and low cost. However, the development of zygotes generated from these sperms was poor. Here, we demonstrated that the(More)
A study involving 32 sexual mature females was conducted to characterize ovulation, fertilization and early embryonic development in vivo in raccoon dogs. Oocytes and embryos were collected from the oviducts and uteri, evaluated by stereomicroscopy. Ovulation occurred 25-32h after a female first accepted mounting, regardless of copulation, when the females(More)
