In somatic cell cloning, the cell cycle phase of the donor cells has critical impact on nuclear reprogramming and chromosomal normality of the reconstructed embryos. Recently, enhanced development to full term was obtained with embryos reconstructed

Low developmental rates after IVF with some AI bulls are one of the most frequent problems encountered with in vitro production of bovine embryos. In this study, two groups of high and low in vitro fertility bulls (3 bulls per group) were selected ba

Lamin A/C expression is generally associated with terminally differentiated cell types; however, numerous conflicting reports in the literature demonstrate the presence of lamins A/C in pluripotent cells of pre-implantation embryos. This study charac

The quantity and quality of semen may affect conception rate after artificial insemination (AI). The concentration of motile spermatozoa, after thawing, varies according to the sire and lot of frozen semen used. The minimum amount of spermatozoa requ

The LH receptor (LHr) present in ovarian follicle cells is essential for the biological response due to its binding to the ligand (LH). The events following the LH surge are related to the presence of LHr and its affinity to LH. Studies on LHr gene e

Until now, the major obstacle associated with the extensive use of in vitro-produced bovine embryos is the lack of suitable methods to cryopreserve them. At least two approaches exist for overcoming this problem. One is to adjust cryopreservation met

Microinsemination is a technique that delivers male germ cells directly into the ooplasm. The efficiency of fertilization and subsequent embryo development after microinsemination varies with species and the male germ cells used. This study examined

The present study was conducted to characterise and localise the progesterone receptor (PR) on canine spermatozoa. Using a progesterone-bovine serum albumin-fluorescein isothiocyanate conjugate (PBF) and different monoclonal antibodies (C262 and NCL-

Embryo storage before embryo transfer is a necessity in field MOET to enable complex embryo analysis. Cryopreservation of biopsied embryos may reduce pregnancy rates to unacceptable levels, below 40% (Shea BF 1999 Theriogenology 51, 841–854). Our p

Mitogen-activated protein kinase (MAPK) is involved in many signal processes within eukaryotic organisms. Its active form is phosphorylated. For meiotic resumption in oocytes the MAPK cascade plays a central role, because it participates in the trans
