The effect of silicon-containing compounds on development of Bos Taurus preimplantation embryons

Abstract

In the nanoscale state, many substances acquire unique properties, become biologically more active, which opens up new possibilities for their use in pharmacology and veterinary medicine. Nevertheless, the mechanisms of the influence of nanomaterials on biological objects are still unclear [3]. The aim of this study - the evaluation of the effect of silicon-containing compounds (nanoparticles HDS and DMCG) on fertilization of donor bovine oocytes and the development of pre-implantation embryos in vitro. The object - cumulus - oocyte complexes (СОС), aspirated from follicles of the bovine ovaries. Culture of oocytes was performed in medium TC-199 with glutamax-1 (Gibco, Invitrogen Co., Scotland, UK) supplemented with 25 mM sodium pyruvate, 100 IU / ml penicillin G, 100 pg / ml streptomycin, 1 pg / ml β-estradiol, 10 ng / ml FSH and 10% fetal bovine serum (Gibco, Invitrogen Co., Scotland, UK). The experimental groups were supplemented with HDS nanoparticles (AA Chuiko Institute of Surface Chemistry, National Academy of Sciences of Ukraine, Ukraine) and DMSG (Institute of Organic Synthesis named after I.Ya. Postovsky, Russia) at concentrations of 0.001%, 0.2% or 0.4% of the volume of the medium, respectively. There are no significant differences in the level of cleavage and in the proportion of embryos reached the blastocyst stage between the control group and the group of oocytes matured in the presence of 0.2% and 0.4% of DMCG. Addition of nanoparticles in cultural medium increased cleavage rate and the number of blastocysts (78% and 39%, respectively, P <0.001, P <0.005, P <0.05). In general, the results of this study can be used to modernize the maturation system of donor oocytes by introducing silicon-containing compounds into the cultural medium. The absence of the cytotoxic effect of DMSG suggests the possibility of usage DMSG as a component of 3D systems for the culture of female gametes.
