Co-culture of pre-implantation embryos with oviducal epithelial cells mimics the in vivo conditions, thus, playing a crucial role in embryo metabolism and gene expression and finally supporting embryonic developmental competence in several ways. Hence, the objective of the present study was to evaluate the effect of goat oviducal epithelial cells (GOEC) co-culture on goat parthenogenetic embryonic development, quality, and relative mRNA abundance of genes related to developmental competence and oxidative stress. The GOEC were obtained from goat oviducts by squeezing and thorough washing with TCM-199 + 10% fetal bovine serum. Goat cumulus–oocyte complexes were collected from slaughterhouse ovaries and matured in TCM-199 + 10% fetal bovine serum supplemented with 5 μg mL−1 of FSH, 10 μg mL−1 of LH, and 1 μg mL−1 of β-oestradiol for 27 h in CO2 incubator with 5% CO2 and at 38.5°C with >95% RH. In vitro matured cumulus–oocyte complexes were denuded and activated with 5 μM calcium ionophore and 2 mM 6-DMAP. Following activation, embryos were co-cultured with and without GOEC (control) in mCR2aa media. The blastocyst development rate was significantly (P < 0.05) higher (23.00 ± 1.15% v. 17.33 ± 1.45%) in the media cultured with GOEC than in control. The total cell number of blastocysts (n = 4) was also found to be significantly more (167.25 ± 17.51 v. 110.25 ± 12.02) than that of control (P < 0.05). However, the apoptotic index (3.76 ± 0.23% v. 7.97 ± 1.99%) was not significantly different in both groups. Further, RNA was isolated from both groups (20 each) of blastocysts on Day 8, and cDNA was prepared. Analysis by qPCR revealed that the relative mRNA abundance of development related genes, i.e. VEGF, BMP4, and CCNB1, showed significantly high (P < 0.05) expression, whereas the expression of CRABP1 was significantly low (P < 0.05) in GOEC co-culture than control. Oxidative stress related genes GPX-1 and SOD2 had comparable expression in both the culture systems, whereas a nonsignificant (P < 0.05) increase in expression of PRDX1 was observed in GOEC co-culture group. In conclusion, co-culture of embryos with GOEC in the simple culture media like mCR2aa helps in improving developmental competence and quality of parthenogenetic embryos.

Создание эффективной унифицированной системы дозревания донорских ооцитов обеспечит повышение результативности инновационных клеточных репродуктивных технологий. В исследовании проведен сравнительный мониторинг показателеймейотического созревания ооцитов коров, созревших в различных системах, дополненных структурными компонентами фолликулов (СКФ стенки фолликулов, клетки гранулезы, белки) и фолликулярной жидкостью,а также потенций к развитию из них доимплантационных эмбрионов. Анализу подверглись ооциты, прокультивированные в следующих системах:среда ТС199 с добавлением 10 фетальной бычьей сыворотки (ФБС), 50 мкг/мл эстрадиола, 10 мкг/мл лютеинизирующего гормона (ЛГ), 10 мкг/мл фолликулостимулирующего гормона (ФСГ) среда ТС199 с 10 эстральной сывороткой коров среда ТС199 с 50 жидкости из фолликулов диаметром 9 мм среда ТС199 с добавлением белков фолликулярной жидкости молекулярной массой 65 кДасреда ТС199 с 10 ФБС и 1106 клеток гранулезы среда ТС199 с 10 ФБС и тканью фолликула. В культуральные среды ко всем исследованным группам ооцитов добавляли антибиотики. Использование CКФ обеспечило значительное снижение доли ооцитов с дегенерированным хроматином, что способствовало увеличению уровня доимпланационных эмбрионов на стадии бластоцисты. Так, доля бластоцист, развившихся из ооцитов, созревших в среде со стенками фолликулов,составила43,5. В этой же группе выявлен минимальный уровень дегенерированных зародышей (6,45). Полученные данные предлагается использовать при моделировании систем дозревания ооцитов коров с целью повышения качества яйцеклеток.The creation of an effective unified maturation system of donor oocytes provides an increase in the efficiency of innovative cellular reproductive technologies. The comparative analysis of the meiotic maturation indicators of bovine oocytes, which were matured in different cultural systems modified by follicular structural components (FSC follicular walls, granulosa cells, proteins) and follicular fluid, as well as the potential for preimplantation embryonic development were evaluated in this study. Oocytes matured in following cultural systems: medium TC199 supplemented with 10 fetal bovine serum and 50 g/ml of estradiol, 10 g/ml of luteinizing hormone (LH), 10 g/ml of folliclestimulating hormone (FSH) medium TC199 with 10 estrous cow serum medium TC199 with 50 liquid from follicles with a diameter of 9 mm medium TC199 supplemented with the follicular fluid proteins with molecular weight 65 kDa medium TC199 with 10 fetal bovine serum and 1106 granulosa cells medium TC199 with the addition of 10 fetal bovine serum and follicle tissues were analyzed. Antibiotics were added to cultural media of all experimental groups of oocytes. The usage of FSC ensured the decrease in the proportion of oocytes with degenerated chromatin, which contribute the rise of the level of preimplantation embryos at the blastocyst stage. Thus, the proportion of blastocysts developed from oocytes matured in medium supplemented with follicular walls was 43.5. In the same experimental group, the number of degenerated embryos was 6.45. The obtained data are supposed to be used for modeling the cultural systems of cow oocytes in order to improve the egg quality.

One thousand lots of pooled fetal bovine serum (FBS) were tested for contamination with bovine viral diarrhea virus (BVDV) and/or for contamination with neutralizing antibody against BVDV. Noncytopathic or cytopathic BVDV was isolated from 203 lots of FBS. Analysis of the viral isolates identified 115 type 1 and 65 type 2 BVDV isolates. An additional 23 virus isolates were mixtures of >2 BVDV isolates and were not classified to viral genotype. Further characterization of the type 1 viruses identified 51 subgenotype 1a and 64 subgenotype 1b BVDV isolates. Viral neutralizing antibody was detected in 113 lots of FBS. Differential viral neutralization indicated that type 1 BVDV induced the antibody detected in 48 lots of FBS and type 2 BVDV induced the antibody detected in 16 lots of FBS.
