A number of germ cell-specific transcription factors essential for ovarian formation and folliculogenesis have been identified and studied. However, the role of these factors during early embryonic development has been poorly explored. In the present study, we investigated the role of SEBOX, a maternal homeobox transcription factor, during early embryonic development in porcine parthenotes. mRN...

Parthenogenetic activation of human oocytes obtained from infertility treatments has gained new interest in recent years as an alternative approach to create embryos with no reproductive purpose for research in areas such as assisted reproduction technologies itself, somatic cell, and nuclear transfer experiments and for derivation of clinical grade pluripotent embryonic stem cells for regenera...

Rabbit embryonic stem (rES) cells can be derived from various sources of embryos. However, understanding of the gene expression profile, which distincts embryonic stem (ES) cells from other cell types, is still extremely limited. In this study, we compared the protein profiles of three independent lines of rabbit cells, i.e., fibroblasts, fertilized embryo-derived stem (f-rES) cells, and parthe...

ETRAPLOID perennial teosinte, Zea psrennis (Hitchc. ) Reeves and ManTgelsd. is the only close relative of the annual Zea, including maize and 2n teosinte, that has the ability to regrow after producing seed. The other Zea, like most annuals, die during seed maturation. The tetraploid form retains totipotency in basal axillary buds and branches throughout the period when the older culms produce ...

The aim of the study was to compare the parthenogenetic activation and in vitro fertilization (IVF) of in vitro matured caprine oocytes. A total of 881 cumulus-oocyte complexes (COC’s) were collected from 243 ovaries. Oocytes were matured in TCM-199 medium containing eCG (20 IU/ml), hCG (20 IUμg/ml), oestradiol-17β (1 μg/ml), BSA embryo tested (3 mg/ml) supplemented with 10% fetal bovine serum ...
