This study aimed to examine the effects of treatment with glucuronic acid (GA) and N-acetyl-D-glucosamine (AG), which are components of hyaluronic acid (HA), during porcine oocyte in vitro maturation (IVM). We measured the diameter of the oocyte, the thickness of the perivitelline space (PVS), the reactive oxygen species (ROS) level, and the expression of cumulus cell expansion and ROS-related genes and examined the cortical granule (CG) reaction of oocytes. The addition of 0.05 mM GA and 0.05 mM AG during the first 22 h of oocyte IVM significantly increased oocyte diameter and PVS size compared with the control (non-treatment). The addition of GA and AG reduced the intra-oocyte ROS content and improved the CG of the oocyte. GA and AG treatment increased the expression of CD44 and CX43 in cumulus cells and PRDX1 and TXN2 in oocytes. In both the chemically defined and the complex medium (Medium-199 + porcine follicular fluid), oocytes derived from the GA and AG treatments presented significantly higher blastocyst rates than the control after parthenogenesis (PA) and somatic cell nuclear transfer (SCNT). In conclusion, the addition of GA and AG during IVM in pig oocytes has beneficial effects on oocyte IVM and early embryonic development after PA and SCNT.

Growth differentiation factor-8 (GDF8) is a member of the transforming growth factor-β that has been identified as a strong physiological regulator. SB-431542 (SB) is a specific inhibitor of transforming growth factor-β superfamily type I activin receptor-like kinase (ALK) receptors such as ALK4, ALK5, and ALK7. The purpose of this study is investigation of the effects of GDF8 and SB on porcine oocytes during in vitro maturation and subsequent embryonic development. We first performed ELISA to detect GDF8 concentrations in follicular fluid for each size of follicle; sizes were as follows: small (<3 mm), medium (>3 mm and <6 mm), and large (>6 mm) follicle. After detection of the GDF8 concentration in follicular fluid, we investigated the effect of GDF8 and SB treatment during in vitro maturation (IVM) on nuclear maturation, intracellular glutathione (GSH), and reactive oxygen species (ROS) levels, and embryonic development after IVF and parthenogenetic activation (PA). Data were analysed by ANOVA followed by Duncan using SPSS (Statistical Package for Social Science, IBM, New York, NY, USA) mean ± SEM. The ELISA result showed different concentrations of GDF8 for each grade of follicular fluid: small, 0.479 ng mL–1; medium, 0.668 ng mL–1; and large, 1.318 ng mL–1. During the IVM process, 1.318 ng mL–1 of GDF8 and 5 ng mL–1 of SB were added to the maturation medium as control, SB, SB+GDF8, and GDF8 treatment groups. After 44 h of IVM, GDF8 group (90.4%) showed a significantly higher nuclear maturation rate than control and SB+GDF8 groups (85.4 and 81.7%). The SB group (78.9%) showed significantly reduced nuclear maturation rate compared with control (P < 0.05). The GDF8 treatment group showed a significant decreased intracellular ROS and increased GSH levels compared with other groups (P < 0.05). The SB+GBF8 treatment group showed a significantly better cytoplasmic maturation than the SB treatment group. In the PA embryonic development analysis, the GDF8 treatment group showed a significantly higher blastocyst formation rate compared with other groups (47.9, 37.2, 46.4, and 58.7% respectively; P < 0.05). In the IVF embryonic development analysis, the GDF8 treatment groups showed significantly higher blastocyst formation rate compared with the SB group (28.2 and 42.2%, respectively; P < 0.05). In conclusion, treatment with GDF8 during porcine oocyte IVM improved the embryonic developmental competence via increased cytoplasmic maturation and led to better oocyte maturation from the ALK receptor inhibition by SB.

Summary The aim of the present study was to investigate the effects of porcine follicular fluid (pFF) from large-sized (LFF; >8 mm in diameter) and medium-sized (MFF; 3–6 mm in diameter) follicles on the maturation and developmental competence of porcine oocytes. Cumulus–oocyte complexes (COCs) were collected from follicles 3–6 mm in diameter. The collected COCs were incubated for 22 h with LFF or MFF (in vitro maturation (IVM)-I stage) and were incubated subsequently for 22 h with LFF or MFF (IVM-II stage). Cumulus expansion was confirmed after the IVM-I stage and nuclear maturation was evaluated after the IVM-II stage. Intracellular glutathione (GSH) and reactive oxygen species (ROS) levels were measured and embryonic development was evaluated. Relative cumulus expansion and GSH levels were higher in the LFF group compared with in the MFF group after the IVM-I stage (P < 0.05). After the IVM-II stage, the numbers of oocytes in metaphase-II were increased in the LFF group and GSH content was higher in all of the LFF treatment groups compared with in the MFF treatment groups during both IVM stages (P < 0.05). ROS levels were reduced by LFF treatment regardless of IVM stage (P < 0.05). Blastocyst formation and the total numbers of cells in blastocysts were increased in all LFF treatment groups compared with the control group (P < 0.05). These results suggested that pFF from large follicles at the IVM stage could improve nucleic and cytoplasmic maturation status and further embryonic development through reducing ROS levels and enhancing responsiveness to gonadotropins.
