Abstract
OBJECTIVE In vitro maturation (IVM) and cryopreservation of oocytes are two important parts of assisted reproductive technology (ART), but their efficacy is low. This study aimed to improve the quality of in vitro vitrified-warmed maturated oocytes using granulosa cell conditioned medium (GCCM). MATERIALS AND METHODS In the experimental study, fresh/non-vitrified and vitrified-warmed mouse germinal vesicle (GV) oocytes (as F and V) were In vitro maturated using basal medium (BM) and also BM supplemented with 50% GCCM as treated groups (GM), and categorized as FBM, FGM, VBM and VGM groups, respectively. The rate of successful IVM (MII oocyte formation), mitochondrial membrane potential and the viability of MII oocytes were determined using inverted microscopy, JC-1 and trypan blue staining. Then, the rate of In vitro fertilization (IVF) and subsequent two-cell embryo formation was calculated. Finally, the expression levels of Oct4, Sox2, Cdk-2, Gdf9, Integrin beta1 and Igf2 were analyzed using real-time polymerase chain reaction (PCR) in MII oocytes and two-cell embryos. RESULTS These analyses showed that GCCM significantly increased the IVM rate, oocyte meiotic resumption and mitochondrial membrane potential (P<0.05). In addition, the rate of IVF and two-cell embryo formation was significantly higher in FGM and VGM compared to FBM and VBM (P<0.05). Interestingly, GCCM significantly affected the expression of the studied genes. CONCLUSION Our findings suggest that GCCM might be useful for improving the efficiency of IVM and the subsequent IVF outcomes.

Abstract
Assisted reproductive techniques (ARTs), such as artificial insemination, in vitro fertilization, and cryopreservation of gametes/zygotes, have been developed to improve breeding and reproduction of livestock and for the treatment of human infertility. Their widespread use has contributed to improvements in human health and welfare. However, in dogs, only artificial insemination using frozen semen is readily available as an ART to improve breeding and control genetic diversity. A recent priority in sperm cryopreservation is the development of alternatives to egg yolk, which is widely used as a component of the sperm extender. Egg yolk can vary in composition among batches and is prone to contamination by animal pathogens. The latter can be a problem for international exchange of cryopreserved semen. Low-density lipoprotein and skim milk are promising candidates for use as extenders, to ensure fertility after artificial insemination. Although not tested for its effects on fertility following artificial insemination, polyvinyl alcohol may also be a useful alternative to egg yolk as an extender. The development of cryopreservation techniques for canine embryos lags behind that for other mammals, including humans. However, given the success of non-surgical embryo transfer in 2011, studies have sought to refine this approach for practical use. Research on sperm cryopreservation has yielded satisfactory results. However, investigation of other approaches, such as cryopreservation of oocytes and gonadal tissues, remains insufficient. Techniques for the efficient induction of estrus may aid in the development of successful canine ARTs.

Beneficial Effects of L-Carnitine Supplementation during IVM of Canine Oocytes on Their Nuclear Maturation and Development In Vitro. Animals (Basel) 2021; 11:ani11020581. [PMID: 33672295 PMCID: PMC7927128 DOI: 10.3390/ani11020581] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2021] [Revised: 02/12/2021] [Accepted: 02/15/2021] [Indexed: 02/06/2023] Open
Abstract
Simple Summary In vitro production of canine embryos is a technique that can be used as a model to conserve endangered species and to establish efficient breeding systems for domestic dogs. However, compared with other species, the success rates of in vitro embryo production (IVEP) in dogs are low. L-Carnitine (LC) is a small water-soluble molecule; it plays an essential role in fatty acid metabolism and acts as a potent antioxidant. Various studies have reported the beneficial impacts of LC on IVEP in many mammalian species other than dogs. Therefore, these experiments investigated the effects of LC supplementation during in vitro maturation (IVM) on canine oocytes maturation, fertilization, and development in vitro. We show that the supplementation of IVM media with LC has positive impacts on oocyte maturation, fertilization, and preimplantation embryo development rates. We also demonstrate that 0.6 mg/mL LC is the most beneficial concentration to be used. It resulted in significantly higher maturation, fertilization, and embryo developmental rates than the control and other LC concentrations. These outcomes are essential for refining the IVM conditions that can advance the efficiency of assisted reproductive technologies (ARTs) in dogs. Abstract This study aimed to investigate the effect of L-Carnitine (LC) supplementation during in vitro maturation (IVM) of canine oocytes on nuclear maturation, fertilization status, and preimplantation development. Cumulus–oocyte complexes (COCs) collected from the ovaries of ovariohysterectomized female dogs were matured in vitro for 72 h in a TCM-199 medium supplemented with (0.1, 0.3, 0.6, 1.0, or 2.0 mg/mL) or without (0.0 mg/mL) LC. Matured oocytes were fertilized in vitro with frozen–thawed spermatozoa, and zygotes were cultured in a SOF medium for 7 days. IVM rates were higher (p ≤ 0.05) in 0.3 and 0.6 mg/mL LC supplemented groups than in the control (0.0 mg/mL LC) and other LC groups. Fertilization (18 h postinsemination (pi)) and cleavage (2–16-cell stage at day 3 pi) rates were higher (p ≤ 0.05) in the 0.6 mg/mL LC group than in the control and 0.1, 1.0, and 2 mg/mL LC supplemented groups. Interestingly, 4.5% of fertilized oocytes developed to morula (day 5 pi) in the 0.6 mg/mL LC group, which was higher (p ≤ 0.05) than those developed in the 0.3 mg/mL group (1.0%). No cleaved embryos developed to morula in other groups. In conclusion, LC supplementation at 0.6 mg/mL during IVM of canine oocytes improved their maturation, fertilization, and preimplantation embryo development rates following IVF and in vitro culture (IVC).

The effect of the human cumulus cells-conditioned medium on in vitro maturation of mouse oocyte: An experimental study. Int J Reprod Biomed 2020; 18:1019-1028. [PMID: 33426412 PMCID: PMC7778757 DOI: 10.18502/ijrm.v18i12.8023] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2020] [Revised: 07/12/2020] [Accepted: 07/29/2020] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND To increase the results of infertility treatment, many efforts have been made to improve the treatment methods. As assisted reproductive technology is mainly using cell culture methods, one of the approaches to improve this technology is conditioned medium from different sources. It is desirable to apply in vitro maturation (IVM) and use oocytes from normal cycles instead of stimulating ovulation. OBJECTIVE To investigate the effect of human cumulus cell condition medium (hCCCM) on the IVM of immature mouse oocytes and morphology. MATERIALS AND METHODS In this experimental study, 240 germinal vesile oocytes were collected from four-six wk-old mice after 48 hr of 5IU pregnant mare serum gonadotropin (PMSG) injection and cultured in hCCCM (test group, n = 120) and DMEM + 20% FBS (control group, n = 120). The IVM rates and changes in perivitelline space (PVS) and shape were investigated at 8, 16, and 24 hr following the culture. The mature (MII) oocytes were subjected to in vitro fertilization (IVF) and the fertilization rate was assessed in three days. RESULTS A significant difference was observed between the maturation rates in the hCCCM and control groups (24.16% vs 0%; p = 0.001), as well as morphologic changes between the two groups (p = 0.04, p = 0.05). The development rate for MII oocytes attained from IVM in the hCCCM group was 27.58% (2-cell) and 6.89% (4-cell). Data displayed that hCCCM is an effective medium for oocytes maturation compared to the control medium. CONCLUSION hCCCM supports oocyte in vitro growth and maturation. Moreover, hCCCM changes the oocyte shape and size of perivitelline space.

INTERNATIONAL JOURNAL OF FERTILITY & STERILITY 2020; 14:175-184. [PMID: 33098383 PMCID: PMC7604698 DOI: 10.22074/ijfs.2020.6097] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/17/2019] [Accepted: 04/10/2020] [Indexed: 12/25/2022]
Abstract
Background Testicular cell conditioned medium (TCCM) has been shown to induce female germ cell development
in vitro from embryonic stem cells (ESCs). Testicular cells (TCs) secrete a variety of growth factors such as growth
differentiation factor-9 (GDF-9), bone morphogenetic protein 4 (BMP-4), stem cell factor (SCF), leukemia inhibitory
factor (LIF), and other, that could improve oocyte maturation. Here we have investigated the effect of human TCCM
(hTCCM) on in vitro maturation (IVM) and morphology of mouse oocytes. Materials and Methods In this experimental study, 360 germinal vesicle (GV) oocytes were obtained from NMRI
mice, aged 4-6 weeks that had received 5 IU pregnant mare's serum gonadotropin (PMSG) 48 hours before. GV
oocytes were subjected to IVM. 120 GV oocytes were cultured in each medium; hTCCM as the test group, DMEM
+ 20%FBS as the control group and Ham’s F10 + HFF medium as the sham group. The rates of the IVM and perivi-
telline space (PVS) changes were recorded at 8, 16 and 24 hours after culture. The metaphase II (MII) oocytes were
subjected for in vitro fertilization (IVF) and the fertilization rate was evaluated after 1, 2, and 3 days. Results There was a significant difference between the maturation rates in hTCCM (31.67% MII) and the control [0% MII,
P<0.05, (7.5% MI, 52.5% deg. and 40%GV)] groups but there was not a significant difference between the maturation rates
in hTCCM and the sham group (53.33% MII, P>0.05). IVF success rate for MII oocytes obtained from IVM in the hTCCM
group was 28.94% (n=11). Our data showed that hTCCM is an effective medium for GV oocyte growth and maturation
compared to the control medium. Conclusion Our findings show that TCCM supports oocyte IVM in mice and affect oocyte morphology.

Abstract
Background Cumulus cells, as oocyte nurse cells, provide a suitable microenvironment with growth factors and cellular interactions required for oocyte maturation. Thus, these cells may serve as a natural niche for in vitro studies of female germ cell development. Cumulus cells may help attain a better understanding of the causes of infertility in women and eventually improve the outcomes of cases that respond poorly to standard infertility treatment. Objective The aim of this study was to isolate, culture, and investigate the biological characteristics of human cumulus cells. Materials and Methods In this experimental study, cumulus cells were isolated, cultured, and characterized using reverse transcription-polymerase chain reaction analyses of specific genes including FOXL2, CYP19A1, FSHR, AMHR, and LHR. The presence of vimentin, a structural protein, was examined via immunofluorescent staining. Moreover, levels of anti-mullerian hormone (AMH) and progesterone secretion by cumulus cells were measured with ELISA after 2, 4, 12, 24, and 48 hr of culture. Results In adherent culture, human cumulus cells expressed specific genes and markers as well as secreted AMH and progesterone into the medium. Conclusion Cumulus cells secrete AMH and progesterone in an adherent culture and might be applicable for in vitro maturation (IVM) and in vitro gametogenesis (IVG) studies.
