The aim of this study was to evaluate the influence of a vitrification-warming procedure on the viability of cat embryos and blastocysts and the incidence of apoptotic changes in blastocysts subjected...
DNA methylation undergoes dynamic changes and is a crucial part of the epigenetic regulation during mammalian early development. To determine the DNA methylation levels in bovine embryos, we applied a...
New research on the teeth of fossilized dinosaur embryos indicates that the eggs of non-avian dinosaurs took a long time to hatch—between about three and six months. The study, led by scientists at Fl...
Somatic cell nuclear transfer (SCNT) is a useful tool for animal cloning, but the efficiency of producing viable offspring by SCNT is very low. To improve this efficiency in the production of cloned p...
Lipovitellin, the predominant yolk protein of vertebrate eggs, is a mixture of heat-stable and heat-labile molecules in mature winter flounder eggs. The heat-stable lipovitellin fraction, purified fro...
Somatic cell nuclear transfer (SCNT) has generally demonstrated that a differentiated cell can convert into a undifferentiated or pluripotent state. In the SCNT experiment, nuclear reprogramming is in...
Many different approaches have been developed to improve the efficiency of animal cloning by somatic cell nuclear transfer (SCNT), one of which is to modify histone acetylation levels using histone de...
The glycosaminoglycans (GAGs) present in the female reproductive tract promote sperm capacitation. When bovine sperm were exposed to 10 μg/ml of one of four GAGs (Chondroitin sulfate, CS; Dermatan sul...
Fertilization of the oocyte commences embryogenesis during which maternally inherited mRNAs are degraded and the embryonic genome is activated. Transcription of embryonic mRNA is initiated by embryoni...
Modeling the formation of Uranus and Neptune is a long-lasting problem in planetary science. Due to the gas-drag, collisional damping, and resonant shepherding, the planetary embryos repel the planete...
This study was carried out to examine the influence of minimum essential medium (MEM) vitamins supplementation to in vitro maturation medium and in vitro culture medium on the development of porcine e...
The objective of the present study was to elucidate the fundamental mechanism of bovine oviduct epithelial cell (BOEC) co-culture on developmental capacity of bovine IVM/IVF embryos and to determine w...
RNA interference (RNAi) is an acknowledged useful and effective tool to study gene function in various cells. Here, we suppressed the Connexin 43 (Cx 43) gene expression during in vitro development of...
This study investigated the effects of IGF-I and EGF on the development of blastocysts or hatched blastocysts during the in vitro culture of embryos from immature porcine oocytes. After the in vitro m...
The aim of this study was to compare the effects of oviductal fluid, porcine zygote medium (PZM)-3, PZM-4 and PZM-5, and modified PZM-5 culture media, and determine the effects of zona pellucida (ZP) ...
