The use of peripubertal donors in embryo transfer (ET) programs presents significant opportunity to accelerate genetic gain in domestic livestock by reducing the generation interval. These studies were designed to evaluate feasibility of superovulati

The present experiments were conducted to optimize in vitro fertilization conditions for zona pellucida-free (ZP-free) oocytes and their subsequent development. The results demonstrated that: (1) maximal fertilization efficiency was achieved at 200 s

The ubiquitin-proteasome pathway has been implicated in the penetration of ascidian vitelline envelope by the fertilizing spermatozoon (Sawada et al., Proc Natl Acad Sci U S A 2002; 99:1223-1228). The present study provides experimental evidence demo

The object of this study was to investigate the role of epidermal growth factor (EGF) and IGF-I in the regulation of preantral follicular growth, antrum formation, and granulosal cell proliferation/ apoptosis. Porcine preantral follicles were manuall

A cytogenetic study was undertaken to quantify, by chromosomal karyotyping, the incidence and type of chromosomal abnormalities present in Day-6 in vitro-produced (IVP) porcine embryos. Morphologically normal Day-6 blastocysts (n=318) were fixed and

Oviduct-specific glycoprotein (OGP) displays estrus-associated regional and temporal differences in expression and localizes to the zona pellucida, perivitelline space, and plasma membrane of oviductal oocytes and embryos, suggesting that it may have

Ubiquitin-dependent proteolysis has been implicated in the recognition and selective elimination of paternal mitochondria and mitochondrial DNA (mtDNA) after fertilization in mammals. Initial evidence suggests that this process is contributed to by l

Developing a culture system for preantral follicles has important biotechnological implications due to the potential to produce large number of oocytes for embryo production and transfer. As an initial step toward accomplishing this long-term goal, a

Butyrolactone I specifically inhibits M-phase promoting factor activation and prevents the resumption of meiosis. These experiments were conducted to examine effects of butyrolactone I on pig oocytes in a serum-free maturation system. The first exper

Sperm agglutination antigen-1 (SAGA-1) is a human male reproductive tract glycoform of CD52. Unique modification of CD52 N-linked oligosaccharide chains in the epididymis and vas deferens results in the appearance of a carbohydrate epitope that is lo
