Optimization of human recombinant granulocyte-colony stimulating factor supplementation during in vitro production of porcine embryos to improve the efficiency of resource utilization of poor-quality cumulus-oocyte complexes. Theriogenology 2024; 216:93-102. [PMID: 38159389 DOI: 10.1016/j.theriogenology.2023.12.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2023] [Revised: 12/11/2023] [Accepted: 12/12/2023] [Indexed: 01/03/2024]
Abstract
Granulocyte colony-stimulating factor (G-CSF), a pleiotropic cytokine, is secreted by the reproductive tract. Furthermore, our previous study indicated that human recombinant G-CSF (hrG-CSF) supplementation during porcine oocyte in vitro maturation (IVM) or during embryo in vitro culture (IVC) improved their quality and development potential when using cumulus-oocyte complexes (COCs) with more than three cumulus cell layers (CCL >3). Thus, in this study, we investigate the optimal conditions of hrG-CSF supplementation throughout the in vitro production (IVP: IVM + IVC) system to improve the embryo production efficiency of "poor-quality (CCL ≤3)" oocytes. COCs were classified into two groups according to the number of CCL (>3 and ≤3) and embryonic viability was analyzed after treatment with hrG-CSF during IVC. The mRNA transcription levels of G-CSF in COCs were compared based on their type and the period of IVM. Finally, developmental capacity and quality were evaluated after treatment with hrG-CSF for different periods of IVP. No marked effects on the developmental potential of embryos when using CCL ≤3 type COCs were observed after supplementing hrG-CSF only during IVC. Moreover, the mRNA transcription level of G-CSF increased gradually with IVM culture time and was higher in CCL ≤3 COCs than in >3. Supplementing hrG-CSF only during the IVM period resulted in the best embryo developmental potential, while supplementing hrG-CSF during the IVP period resulted in the best quality embryos, reflected in the increased total cell number and decreased apoptotic nuclei index of blastocysts. These findings indicate that "poor-quality" COCs may have a greater demand for G-CSF than "good-quality", meanwhile hrG-CSF supplementation throughout IVP improves resource utilization efficiency in poor-quality COCs.

Abstract
BACKGROUND The collection of ovaries from slaughterhouses is an important source of oocytes for in vitro embryo production. On the other hand, the physiological stage of slaughtered females varies and influences embryo production. OBJECTIVES The study examined the in vitro efficiency of embryos and demi-embryos from young, non-pregnant adult, and pregnant adult ewes from a local slaughterhouse. METHODS One thousand three hundred ovaries were collected from August to October 2020. The recovered oocytes were matured, fertilized, and cultured at 5% CO2, 38.5°C, and 100% humidity. Embryo bisection was performed in 96 blastocysts (n = 32 per treatment). The demi-embryo pairs were incubated for their reconstitution for 12 h. SAS was used for data analysis. RESULTS The number of oocytes collected from the experimental group of non-pregnant adult ewes was higher (p ≤ 0.007) than those collected from the group of pregnant adult ewes (2.67 ± 0.19 vs. 2.18 ± 0.15 oocytes/group, respectively). The blastocyst rate was higher (p ≤ 0.0001) in the non-pregnant adult group (36.39%) than in the young (17.96%). The ratio of demi-embryos that recovered the blastocoelic cavity was higher (p < 0.05) in the young group (81.25%) than in the pregnant adult group (59.38%). The diameter of the demi-embryos was higher (p < 0.05) in the non-pregnant adult group (186.54 ± 8.70 μm) than those in the young and pregnant adult groups. CONCLUSIONS In conclusion, the in vitro embryo production efficiency was highest when using oocytes from non-pregnant adult ewes under the conditions of this study.

Abstract
The present study evaluated the effects of in vitro maturation (IVM) on the proteome of cumulus-oocyte complexes (COCs) from ewes. Extracted COC proteins were analyzed by LC-MS/MS. Differences in protein abundances (p < 0.05) and functional enrichments in immature versus in vitro-matured COCs were evaluated using bioinformatics tools. There were 2550 proteins identified in the COCs, with 89 and 87 proteins exclusive to immature and mature COCs, respectively. IVM caused downregulation of 84 and upregulation of 34 proteins. Major upregulated proteins in mature COCs were dopey_N domain-containing protein, structural maintenance of chromosomes protein, ubiquitin-like modifier-activating enzyme 2. Main downregulated proteins in mature COCs were immunoglobulin heavy constant mu, inter-alpha-trypsin inhibitor heavy chain 2, alpha-2-macroglobulin. Proteins exclusive to mature COCs and upregulated after IVM related to immune response, complement cascade, vesicle-mediated transport, cell cycle, and extracellular matrix organization. Proteins of immature COCs and downregulated after IVM were linked to metabolic processes, immune response, and complement cascade. KEGG pathways and miRNA-regulated genes attributed to downregulated and mature COC proteins related to complement and coagulation cascades, metabolism, humoral response, and B cell-mediated immunity. Thus, IVM influenced the ovine COC proteome. This knowledge supports the future development of efficient IVM protocols for Ovis aries.

Abstract
The present study was conducted to characterize the major proteome of pre-implantation (D6) ovine embryos produced in vitro. COCs were aspirated from antral follicles (2-6 mm), matured and fertilized in vitro, and cultured until day six. Proteins were extracted separately from three pools of 45 embryos and separately run in SDS-PAGE. Proteins from each pool were individually subjected to in-gel digestion followed by LC-MS/MS. Three "raw. files" and protein lists were produced by Pattern Lab software but only proteins present in all three lists were used for the bioinformatics analyses. https://david.ncifcrf.govThere were 2,262 proteins identified in the 6-day old ovine embryos, including albumin, zona pellucida glycoprotein 2, 3 and 4, peptidyl arginine deiminase 6, actin cytoplasmic 1, gamma-actin 1, pyruvate kinase, heat shock protein 90 and protein disulfide isomerase, among others. Major biological processes linked to the sheep embryo proteome were translation, protein transport and protein stabilization, and molecular functions, defined as ATP binding, oxygen carrier activity and oxygen binding. There were 42 enriched functional clusters according to the 2,147 genes (UniProt database). Ten selected clusters with potential association with embryo development included translation, structural constituent of ribosomes, ribosomes, nucleosomes, structural constituent of the cytoskeleton, microtubule-based process, translation initiation factor activity, regulation of translational initiation, cell body and nucleotide biosynthetic process. The most representative KEEG pathways were ribosome, oxidative phosphorylation, glutathione metabolism, gap junction, mineral absorption, DNA replication and cGMP-PKG signaling pathway. Analyses of functional clusters clearly showed differences associated with the proteome of pre-implantation (D6) sheep embryos generated after in vitro fertilization in comparison with in vivo counterparts (Sanchez et al., 2021; https://doi.org/10.1111/rda.13897), confirming that the quality of in vitro derived blastocysts are unlike those produced in vivo. The present study portrays the first comprehensive overview of the proteome of pre-implantational ovine embryos grown in vitro.

Effect of melatonin supplementation during IVM of dromedary camel oocytes (Camelus dromedarius) on their maturation, fertilization, and developmental rates in vitro. Theriogenology 2021; 172:187-192. [PMID: 34218101 DOI: 10.1016/j.theriogenology.2021.05.021] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2020] [Revised: 05/17/2021] [Accepted: 05/17/2021] [Indexed: 01/01/2023]
Abstract
The positive impact of melatonin on in vitro embryo production (IVEP) has been reported in many domestic species; however, no studies have been carried out in camelids. We aimed to evaluate the effects of melatonin supplementation in maturation media on in vitro maturation, fertilization, and preimplantation embryo development of dromedary camel oocytes (experiment 1). We also evaluated the concentrations of total antioxidant capacity (TAC), and malondialdehyde (MDA) in the IVM spent medium in relation to melatonin supplementation. Cumulus oocyte complexes (COCs) were cultured in in vitro maturation media (IVM) supplemented with either 0.0, 25.0, 50.0 or 75.0 μM of melatonin for 30 h. Matured oocytes were then fertilized in vitro with epididymal camel spermatozoa. Following IVF, the resulting embryos were cultured in vitro for seven days. The percentage of maturation, fertilization, cleavage, and embryo developmental rates (morula and blastocyst) was recorded (experiment 1). TAC and MDA levels in the IVM spent maturation media were also evaluated at 30 h post-IVM (experiment 2). The results showed that supplementation of IVM media with 25 μM melatonin significantly improved oocyte nuclear maturation, fertilization (18 h post-insemination; pi), cleavage (day 3 pi), morula (day 5 pi) and blastocyst (day 7 pi) rates as compared with the controls and other melatonin-supplemented groups. Furthermore, the TAC in the IVM spent media was significantly increased (P < 0.05) in 25 μM melatonin supplemented groups than those supplemented with 0.0, 50.0, 75.0 μM melatonin. However, the concentration of MDA was significantly lower (P < 0.05) in IVM media supplemented with 25.0 μM of melatonin when compared with the control and other treatment groups. In conclusion, supplementation of IVM medium with 25 μM of melatonin could enhance the in vitro developmental capacity of dromedary camel oocytes.

Abstract
The aim of this study was to assess the presence and distribution of apoptosis in porcine cumulus-oocyte complexes (COCs) and its relations with COC morphology and developmental competence. The COCs were obtained from slaughterhouse ovaries, classified into A1 (top category), A2, B1, B2, C, and D based on their morphology. A1, A2, and B1 were matured and fertilized in vitro, and blastocyst rate was compared among them. Before and after in vitro maturation (IVM), annexin-V staining, and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assays were performed to assess early and late apoptosis, respectively. There was a significant increase in both annexin-V (+) oocytes and TUNEL (+) cumulus cells as morphology further deteriorated. There were no statistical differences regarding annexin-V (+) oocytes within immature and post-IVM COCs, but TUNEL (+) oocytes were only observed in post-IVM COCs. Early and late apoptosis was detected in cumulus cells of all categories of immature and post-IVM COCs. However, the difference was only significant for annexin-V (+). There were no significant differences in embryo development. Therefore, apoptosis increases as the morphological features of the immature COCs decrease. In conclusion, the selection of COCs from Categories A1, A2, and B1 may be used as a selection criterion for in vitro development.

Effects of co-incubation with conspecific ampulla oviductal epithelial cells and media composition on cryotolerance and developmental competence of in vitro matured sheep oocytes. Theriogenology 2018; 120:10-15. [PMID: 30081243 DOI: 10.1016/j.theriogenology.2018.07.032] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2018] [Revised: 07/04/2018] [Accepted: 07/27/2018] [Indexed: 11/28/2022]
Abstract
Developmental potential of cryopreserved in vitro matured oocytes is very low in nearly all mammalian species studied to date. Despite relatively high cleavage rates, the vitrified/warmed metaphase II oocytes have a decreased rate of blastocyst formation, which can be attributed to the elevated cytoplasmic lipid content and lipid droplet fragmentation. Secretory products of ampulla oviductal epithelial cells (AECs) at the periovulatory stage of the ovarian cycle enhance the viability of in vitro matured oocytes. The present study was undertaken to determine if co-culture of cumulus-oophorus complexes (COCs) with conspecific AECs or reducing the lipid content of in vitro matured ovine oocytes would improve their cryotolerance and ensuing developmental competence. Ovine COCs aspirated from the slaughterhouse ovaries were matured in the following media or culture conditions: TCM199 + FBS + AECs (T1); TCM199 + FBS (T2); TCM199 + BSA (T3); TCM199 + 0.6 mg/mL of l-carnitine (T4); TCM199+ l-carnitine + FBS (T5), or TCM199 only (Ctr). Subsequently, the oocytes were vitrified and used for in vitro fertilization (IVF). The lowest degree of zona pellucida (ZP) hardening following vitrification of in vitro matured sheep oocytes was observed in T1 and T5 (P < 0.05). Cleavage, blastocyst formation and ensuing development (i.e., total cell numbers) as well as blastocyst hatching rates were all greater (P < 0.05) in T1 compared with the remaining groups; in vitro matured COCs in T4 and Ctr did not develop beyond the cleavage stage. The inner cell mass: trophectoderm cell ratio in T1 (1:3.29) was significantly greater compared with T2 (1:3.39), T3 (1:3.40) and T5 (1:3.44). The present results indicate that the ovine COCs/AECs co-culture system had the most positive influence on cryotolerance, ZP hardening, and developmental competence of in vitro matured oocytes.

Melatonin supplementation during prolonged in vitro maturation improves the quality and development of poor-quality porcine oocytes via anti-oxidative and anti-apoptotic effects.

Abstract
Poor-quality oocytes (those with 1-2 layers of cumulus cells) typically possess low meiotic competence and development. Prolonging the duration of in vitro maturation (IVM; 52 hr) can enhance the maturation rate of poor-quality oocytes, but it does not improve subsequent embryonic development. This likely reflects the increased reactive oxygen species (ROS) production and apoptosis seen in these oocytes compared with the non-prolonged IVM (44 hr) group. Melatonin is a free radical scavenger, anti-oxidant and anti-apoptotic agent that reported to enhance the quality of embryos by inhibiting ROS generation and apoptosis. Therefore, we herein investigated whether melatonin combined with prolonged IVM (52 hr) could improve the quality and development of poor-quality oocytes. We supplemented IVM and/or in vitro culture (IVC) media with various concentrations (0, 10-7 , 10-6 , 10-5 M) of melatonin, and estimated parameters related to oocyte quality and development. The addition of melatonin (10-6 M) to a prolonged IVM system improved the oocyte quality and development compared with those of the melatonin-free poor-quality oocytes group, and that this was due to decreases in ROS generation, apoptosis, and DNA damage. When melatonin was added during both IVM (10-6 M) and IVC (10-6 M), we observed a cumulative positive influence on the embryonic development and quality; this treatment enhanced the expression level of Oct4 and decreased the levels of ROS, DNA damage, and apoptosis. Together, these findings suggest that the combination of melatonin plus prolonged IVM can improve the quality and development of poor-quality porcine oocytes via anti-oxidative and anti-apoptotic effects.

In vitro-production of embryos using immature oocytes collected transvaginally from superstimulated wood bison (Bison bison athabascae). Theriogenology 2017; 92:103-110.

Abstract
Two experiments were done to test the hypothesis that morphologic characteristics of wood bison cumulus-oocyte complexes (COC) are reflective of the ability of the oocyte to develop to an advanced embryonic stage after in vitro maturation, fertilization and culture, and to determine the effect of prolonging the interval from the end of superstimulation treatment to oocyte collection (FSH starvation period). Experiments were done during the anovulatory season. In Experiment 1, ovarian superstimulation was induced in 10 bison with two doses of FSH given at 48 h intervals beginning at the time of follicular wave emergence. COC were collected 3 days (72 h) after the last dose of FSH by follicular aspiration and classified as compact, expanded or denuded. The COC were matured in vitro for 24 h before fertilization in vitro (Day 0). Embryo development was assessed on Days 3, 7 and 8. The blastocyst rate was 7/34, 2/10 and 0/3 in COC classified as compact, expanded and denuded, respectively; however, only compact COC resulted in embryos that reached the expanded blastocyst stage. In Experiment 2, COC were collected at either 3 or 4 days (72 or 96 h) after the last dose of FSH (n = 16 bison/group) to determine the effect of the duration of FSH starvation on oocyte competence. The COC were classified as compact good (>3 layers of cumulus cells), compact regular (1-3 layers of cumulus cells), expanded or denuded, and then matured, fertilized and cultured in vitro. Although follicles were larger (P < 0.05) in the 4-day FSH starvation group, there was no effect of starvation period on the distribution of COC morphology; overall, 112/194 (57.7%) were compact, 29/194 (26.3%) were expanded, 39/194 (20.1%) were denuded, and 14/194 (7.2%) were degenerated (P < 0.05). Similarly, there was no effect of starvation period on embryo development. Compact good COC had the highest cleavage (88%) and blastocyst rates (54%; P < 0.05), followed by compact regular COC at 73% and 25%, respectively. Expanded and denuded COC had low cleavage (40% vs. 59%, respectively) and blastocyst rates (5% vs. 8%, respectively). We conclude that morphologic characteristics of wood bison COC are reflective of the ability of the oocyte to develop into an embryo in vitro. Importantly, oocytes collected from superstimulated bison during the anovulatory season were competent to develop to the blastocyst stage following in vitro maturation, fertilization and culture.

The effect of conspecific ampulla oviductal epithelial cells during in vitro maturation on oocyte developmental competence and maturation-promoting factor (MPF) activity in sheep. Theriogenology 2016; 88:207-214. [PMID: 28234231 DOI: 10.1016/j.theriogenology.2016.09.034] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2016] [Revised: 09/10/2016] [Accepted: 09/12/2016] [Indexed: 10/21/2022]
Abstract
The acquisition of fertilization ability by oocytes is one of the prerequisites for successful in vitro embryo production. In the present study, we examined the influence of conspecific ampulla oviductal epithelial cells incubated with cumulus-oocyte complexes (COCs) throughout the IVM phase on the developmental competence and maturation-promoting factor (MPF) activity of sheep oocytes. There were six experimental groups in this study, namely four groups with and two groups without oviductal epithelial cells added to IVM media: adult COCs matured in vitro with the ampulla oviductal epithelial cells obtained from adult (AAE; G1) or prepubertal donors (prepubertal sheep ampulla oviductal epithelial cells [PAE]; G4), COCs obtained from prepubertal animals cocultured with AAE (G2) or PAE (G3), and adult (C1) and prepubertal sheep COCs (C2) matured without oviductal epithelial cells. Coincubation of oocytes retrieved from both adult and sexually immature donors with AAE (G1 and G2) resulted in significantly improved rates of metaphase-II (M-II) attainment (G1: 85.1 ± 2.0 and G2: 40.2 ± 1.3) and blastocyst formation (G1: 42.2 ± 1.1 and G2: 21.2 ± 1.0) as well as blastocyst development (total cell count; G1: 130.3 ± 7.8, G2: 70.2 ± 3.5) compared with their respective controls (C1: 94.3 ± 4.1 and C2: 49.7 ± 2.0). Prior to IVM, the activity of MPF was greater (P < 0.05) for oocytes obtained from ewes (G1, G4, and C1) compared with those from ewe lambs (G2, G3, and C2). The greatest increment in MPF activity was recorded in G2 (MPF activity before IVM/MPF activity after IVM = 3.62) followed by C2 and G3 (2.22 and 2.20, respectively), and then all remaining groups of oocytes (C1: 1.89, G1: 1.87, and G4: 1.86). In summary, coincubation with AAE during the 24-hour IVM had a positive impact on ovine oocyte competence and ensuing in vitro embryo production efficiency. A significant increase in MPF activity following IVM of G2 oocytes could be responsible, at least partly, for the improved rate of blastocyst formation after IVF of prepubertal sheep oocytes.

Abstract
Background: To current knowledge, different oocyte's recovery method and various seasons have profound impact on in vitro embryo production (IVEP). Objectives: The aim of this study was to define an efficient recovery method for oocytes harvesting from slaughterhouse material in different seasons, and their effects on IVEP yield. Materials and Methods: Ovaries from slaughtered ewes in breeding season (BS) and non-breeding season (NBS) were collected from a local abattoir. The oocytes were recovered through aspiration, centrifugation (ORC), puncture and slicing, and categorized into three classes (I, oocytes with more than three layers of cumulus cells; II, less than three layers with damaged cumulus cells; III, denuded oocytes). After cultivation in TCM 199 for 24 hours, matured oocytes were subjected to in vitro fertilization (IVF) and in vitro culture (IVC). The oocyte recovery using ORC in BS and NBS was significantly higher (P < 0.05) compared with other recovery methods. Results: No significant dissimilarities in the proportion of oocytes reaching M-II stage were recorded when using different oocyte recovery methods in different seasons. Aspiration resulted in lower (P < 0.05) proportion of class I (BS, 60.0 ± 2.1; NBS, 51.1 ± 2.1) compared to ORC (BS, 82.0 ± 1.2; NBS, 70.0 ± 1.2), slicing (BS, 80.0 ± 2.1; NBS, 71.0 ± 1.4) and puncture (BS, 80.0 ± 1.5; NBS, 72.0 ± 2.0). Monospermy and blastocyst development rates were significantly higher using ORC than other recovery techniques in both BS and NBS. More oocytes with high quality, greater blastocyst development and oocyte recovery rates were achieved in BS. Conclusions: The results revealed that oocytes harvesting technique and season are effective in the rate of cleavage and blastocysts’ development, and suggest that despite same meiotic resumption rate in all treatments, it would be better to use ORC.

Abstract
BACKGROUND Approximately 20% of recovered oocytes are immature and discarded in intracytoplasmic sperm injection (ICSI) procedures. These oocytes represent a potential resource for both clinical and basic science application. OBJECTIVE The aim of this study was to evaluate the ultrastructure architecture of in vitro matured human oocytes using transmission electron microscopy (TEM). MATERIALS AND METHODS A total of 204 immature oocytes from infertile patients who underwent ICSI cycles were included in this prospective study. Immature oocytes were divided into two groups: (i) GV oocytes (n = 101); and (ii) MI oocytes (n = 103). Supernumerary fresh in vivo matured oocytes (n = 10) were used as control. RESULTS The rates of maturations were 61.38% for GV and 73.78% for MI oocytes in IVM medium (P = 0.07). However, the rate of oocyte arrest was significant between groups (P <0 .05). Ultrastructurally; in vitro and in vivo matured oocytes appeared round, with a homogeneous cytoplasm, an intact oolemma and an intact zona pellucida. However, immature oocytes indicated numerous large mitochondria-vesicle complexes (M-VC). CONCLUSIONS Ultrastructural changes of M-VC in IVM groups emphasize the need for further research in order to refine culture conditions and improve the implantation rate of in-vitro matured oocytes.
