oocyte

As described earlier, the number of a woman's oocytes dwindles to zero over the years.

In the United States, oocytes are infrequently used for basic research in reproductive biology.

CONCLUSION: HBV DNA sequences were able to pass through the zona and oolemma to enter into oocytes and integrate into their chromosomes.

Electron microscope and TUNEL method were used to examine the occurrence of oocytes apoptosis during human fetal folliculogenesis.

Most oocytes used for embryo technology are currently from in vitro maturation (IVM).

The mammalian oocytes are important materials for study of meiotic cell cycle in developmental biology and cell biology.

Objective The aim of this study is to investigate the function of Golgi apparatus during in vitro development of mouse oocytes.

Goat ovaries used in the research were collected from slaughter house. Oocytes were collected with aspiration and slice.

In this paper how the Uracil, ITS, and ATP affect the in vitro maturation(IVM) and viability of bovine oocytes was investigated.

The eggs as mentioned in these Measures refer to the oocytes produced by the ovary of female livestock, including oocytes in vitro culture.

Women with ovulatory dysfunction secondary to ovarian failure or poor ovarian reserve should consider obtaining oocytes from a donor source.

Moreover, during the summer spawning season, the trapped females grow fewer and smaller oocytes, the cells that develop into eggs.

The follicles contained healthy, growing oocytes that were connected by transzonal projections between the somatic cells and oocyte.

Absolute majority oocytes consist in mammalian ovary in preantral follicles, antral follicles only take a small portion.

Configuration of germinal vesicle (GV) chromatin has been studied and found correlated with the developmental competence of oocytes.

The oocytes from the ovaries without corpus luteum got a higher maturing rate in vitro maturation.

The ratios of fused oocytes developed to gastrula and hatching stages, however, were not so different with the control group.

After the completion of culture of oocytes for IVM, cumulus cells were removed. Ultrastructure was studied under electron microscope.

Using of 5 IU dose led to increasing of oocytes number with no differences in their parameters from control ones.

ATP has not significant effect on the maturation rate of the oocytes, however it can enhance the viability of the parthenogenetic embryos.

For the past year, I have been working with a subset of neuronal glutamate receptors via voltage clamping on Xenopus oocytes.

Oocytes are usually donated for reproductive purposes, not for research.

Survival rate of Chinese hamster oocytes (A570) was tested by methyl thiazolyl tetrazolium (MTT) with spectrophotometric determination.

Conclusions: ICSI with oocytes maturated in vitro may have the similar outcome to with those maturated in vivo.

meantime, theNCSU-23 BSA was the best for cultivation effection of oocytes development, after oocytes activation.

In the future, it may also be possible to generate human oocytes from male iPS cells in vitro.

Oocytes were collected from dominant preovulatory follicles of donor mares 24 hours after administration of human chorionic gonadotropin.

Two-electrode whole-cell voltage clamp are used to record I_(ATP) mediated by rat P2X4 receptor expressed in Xenopus oocytes.

The oocytes are covered with test cells and the gonadal development can be divided into 4 stages.

Oocytes and embryos are susceptible to cryo-damage which can even affect cellular ultrastructure.

Therefore, we presumed that the process of denuding may have more detrimental effect on rabbit oocytes than on other animals.

The 23rd chromosome in all oocytes is always an X chromosome.

These results indicated that cumulus cells could offset caffeine's reversible effect on aged oocytes from IVO.

Oocyte preparation and nuclear transfer Recipient oocytes are washed and selected after they are removed from animal.

Objective: To investigate the efficiency of vitrification of immature oocytes to expand the field of gamete cryopreservation.

This paper reviewed the reverse effects of xenobiotics on the meiotic maturation process of oocytes and the mechanism.

The factors affecting in vitro maturation of ovary oocytes and the method of in vitro fertilization were discussed.

Conclusion These results indicated that PAK2 might involved in Xenopus oocytes cytokinesis .

Oocytes with more than 8 layers cumulus cells had lower rate of maturation and cleavage.

Ovarian follicles are consisted with oocytes and the granulosa cells around them.

Oocytes of humans and animals often have long remained at meiotic diplotene.

Nude oocytes and half nude oocytes hardly maturate and cleavage.

However, FGFR2 were located uniformly in the cytoplasm of the oocytes and preimplantation embryos.

The results have shown that pump ways adapt to collect oocytes.

Objective: To observe the effect of Erzhitiangui(EZHTG) decoction on improving the quality of oocytes, and explore its functional mechanism.

Oocytes with 2~8 layers cumulus cells had higher rate of maturation and cleavage in vitro.

The exception to this is the sex cells, sperm, and oocytes or eggs, as these contain only 23 single chromosomes.

The number and diameter of yolk granule rose with the development of oocytes .

Objective To study the ultrastructural changes of wapiti oocytes and provide theoretical basis for wapiti breeding arid reproduction.

Objective: To study the effect of murine cytomegalovirus on the in vitro maturation of mice immature oocytes.

group-synchronous development At least two cohorts of oocytes can be distinguished in the maturing ovary;
