Abstract Traditional methods for the evaluation of oocyte quality are based on morphological classification of the follicle, cumulus-oocyte complex, polar body and meiotic spindle. This study is focused on the differences between the morphological assessment of oocyte quality, the assessment based on Lissamine Green B (LB) staining and the analysis...

Unlike oocytes of many other mammalian species, parthenogenetically activated hamster oocytes have not been reported to develop beyond the two-cell stage. This study investigated the in vitro development into blastocysts of parthenogenetic embryos of Golden Syrian hamsters. We observed that hamster oocytes could easily be artificially activated (AA...

FKBP12, known as FK506 binding protein, binds to immunosuppressive drug FK506, which must be taken by patients who received organ transplant. The side effect of FK506 is that women have difficulties in bearing a baby, so it is important to find the reason of their subfertility. This research explored the expression of FKBP12 in pre-implantation emb...

Nowadays, human oocytes/embryos are cryopreserved via slow freezing or vitrification. The aim of this study was to evaluate a rapid warming protocol for slow-frozen human oocytes based on the standard warming procedure for vitrification. This was a prospective study on 216 sibling oocytes randomized for either conventional rapid thawing or rapid wa...

Principles of Cloning
Since the birth of the first cloned sheep, “Dolly”, many studies have reported the successful use of cloning by somatic cell nuclear transfer in other mammalian species. In spite of these successes, the efficiency of this technique is low, with less than 10% of generated embryos resulting in offspring. Factors of genetic, epigenetic, and technical ...

In the pig, the efficiency of in vitro embryo production and somatic cell nuclear transfer (SCNT) procedures remains limited. It has been suggested that prematuration treatments (pre-IVM) based on the prolongation of a patent, bidirectional crosstalk between the oocyte and the cumulus cells through gap junction mediate communication (GJC), with the...

The effects of chemical activation on birth efficiency of cloned pigs were studied by investigating the developmental process from porcine oocyte activation to birth of cloned pigs. Three different activation methods were used: (i) Electroporation (Ele); (ii) Ele followed by incubation with 6-dimethylaminopurine (6-DMAP); and (iii) Ele followed by ...

Purpose: Spontaneous parthenogenetically activated noninseminated oocytes and failed fertilized oocytes after ART activated by puromycin were studied to assess cleavage ability and the cytogenetic constitution of the resulting embryos. Methods: Failed fertilized oocytes were exposed to puromycin, and whenever activation occurred, they were further ...
