Cloning of domestic species by somatic cell nuclear transfer (SCNT) continues to be inefficient, probably due to an incomplete reprogramming of the reconstituted embryo. The ability of the embryonic cytoplasm to support reprogramming fluctuates withi

Production of cloned nonhuman primate embryos has been reported using mature oocytes obtained from donors treated in vivo with a high dose of recombinant human FSH (r-hFSH, 35 IU per day for 10 days). The disadvantages of this approach are the high c

Laboratory ware for the in vitro-produced embryos is generally made from embryo-tested plastic instead of glass. The quality of the plastic is crucial for the outcome because plastic is often toxic to gametes (Nijs et al. 2009 Fertil. Steril. 92, 527

The aim of this study was to compare the differential effects of the addition of IGF-LongR3 or insulin-like growth factor-1 (IGF-1), during in vitro maturation (IVM) of bovine oocytes on embryonic development, by analysing embryonic viability and apo

The morphology (spherical and without cristae) and metabolism (lowly functional) of mitochondria in early embryos and other rapidly proliferating cells exhibit a Warburg effect (WE)-like metabolism. A hallmark of the WE is the predominate use of glyc

Chitosan is a partially deacetylated polymer obtained from the alkaline deacetylation of chitin, which is a glucose-based unbranched polysaccharide widely distributed in nature as the main component of exoskeletons of crustaceans and insects. Chitosa

Long-term storage of stem cells with self-renewal plays a pivotal role in cell tissue engineering, which could be a novel option for improving regenerative diseases. However, the choice of a selective cryoprotectant is still to be addressed. Dimethyl

Prior to ovulation, interactions of spermatozoa with the oviductal epithelium lead to the formation of a sperm reservoir; here we investigate the hypothesis that the physiological state of the stored spermatozoa is modulated by the epithelial cells.

Currently techniques of TUNEL labelling for detection of apoptosis and differential staining for counting the ratio of inner cell mass (ICM) to trophoectoderm (TE) cells are used separately for assessment of embryo quality in different species. The m

Although an intracellular pH (pHi) increase at the time of fertilization is necessary for activation of the sea urchin egg, recent reports in the mouse and rat have indicated that there is not a pHi increase during fertilization or during 7% ethanol
