Abstract
Feeder cells play important roles in In-vitro culture of stem cells. However, the preparation protocol of feeder cells produced by bovine embryonic fibroblast cells (bEFs) is still lack. In this study, the preparation of bEF-feeder by Mitomycin C was optimized with different concentrations and treatment time. The cell viability of bEFs was detected by CCK8 and 5-Ethynyl-2'-deoxyuridine. The growth of bESCs in each bEFs-feeder group was assessed by alkaline phosphatase staining and CCK8. Quantitative real time PCR was used to detect the mRNA expression of pluripotency-related genes of bESCs. Results showed that the proliferation of bEFs was significantly repressed while bEFs were treated with 14 ug/mL or 16 ug/mL Mitomycin C for 3 h, and the cell viability within 2-4 days after treatment was consistent with the 1st day. The numbers of bESCs clones in bEF-feeder treated with 14 μg/mL Mitomycin C for 3 h or 16 μg/mL Mitomycin C for 3 h were significantly higher than that in bEF-feeder treated with 8 μg/mL Mitomycin C for 8 h or bEFs treated with 6 μg/mL Mitomycin C for 9 h. The mRNA expression of pluripotency-related genes in bESCs cultured by bEF-feeder were higher than the MEF-feeder, the clone morphology of bESCs cultured in bEF-feeder was rounder and sharper than the MEF-feeder. In conclusion, the bEF-feeder prepared with 14 μg/mL Mitomycin C for 3 h or 16 μg/mL Mitomycin C for 3 h could effectively maintains the growth of bESCs, and bEF-feeder is more suitable for bESCs culture than the MEF-feeder.

Reprod Domest Anim 2023; 58:129-140. [PMID: 36178063 DOI: 10.1111/rda.14272] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2022] [Revised: 09/22/2022] [Accepted: 09/24/2022] [Indexed: 01/07/2023]
Abstract
The aims of this study were to analyse the protein phosphatase 1 regulatory subunit 11 (PPP1R11) expression and cellular localization in yak follicles and investigate its effects on cell proliferation, apoptosis and oestrogen secretion in granulosa cells (GCs). Ten healthy and non-pregnant female yaks (4-year-old) were used as experimental animals. The mRNA relative expression level of PPP1R11 in GCs from small (<3.0 mm), medium (3.0-5.9 mm) and large (6.0-9.0 mm) follicles was detected by RT-qPCR, and the cellular localization of PPP1R11 protein was detected by immunohistochemistry staining (IHC). After isolation, culture and identification of yak GCs in vitro, si-PPP1R11 and si-NC (negative control) were transfected into GCs. RT-qPCR and immunofluorescence staining were used to evaluate the interference efficiency, and ELISA was performed to detect oestrogen concentration. Then, EdU staining and TUNEL staining were conducted to analyse cell proliferation and apoptosis. In addition, the oestrogen synthesis, proliferation- and apoptosis-related genes were detected by RT-qPCR after knockdown PPP1R11. The results showed that PPP1R11 is mainly located in ovarian GCs, and the expression levels of PPP1R11 in GCs from large follicles were significantly higher than that from medium and small follicles. Transfection of si-PPP1R11 into GCs could significantly inhibit the expression of PPP1R11. Interestingly, the oestrogen secretion ability and the expression level of oestrogen pathway-related genes (STAR, CYP11A1, CYP19A1 and HSD17B1) were also significantly downregulated. Moreover, the proportion of positive cells was decreased, and cellular proliferation-related genes (PCNA, CCNB1 and CDC25A) were significantly downregulated after knockdown PPP1R11. However, the proportion of apoptotic cells was increased, and apoptosis-related genes (BAX, CASP3 and P53) were significantly upregulated. Taken together, this study was the first revealed the expression and cellular localization of PPP1R11 in yak follicles. Interference PPP1R11 could reduce oestrogen secretion, inhibit proliferation and promote apoptosis in GCs, which provided a basis for further studies on the regulatory mechanism of PPP1R11 in follicle development.

Abstract
Ovarian granulosa cell (OGC) is a critical somatic component of the ovary, which provides physical support and the microenvironment required for the developing oocyte. Human OGCs are easy to obtain and culture as a by-product of follicular aspiration performed during in vitro fertilization (IVF) procedures. Therefore, OGCs offer a potent cell source to generate induced pluripotent stem cells (iPSCs). This study established a novel OGCs-derived iPSC cell line from the follicular fluid of a healthy female donor with a Chinese Han genetic background and named it IPS-OGC-C1. IPS-OGC-C1 was verified for embryonic stem cell morphology, cell marker expression, alkaline phosphatase (AP) activity, transcriptomic profile, and pluripotency capability in developing all three embryonic germ layers in vivo and in vitro.

Abstract
The female reproductive system represents a sensitive target of the harmful effects of cigarette smoke, with folliculogenesis as one of the ovarian processes most affected by this exposure. The aim of this study was to analyze the impact of tobacco smoking on expression of oxidative stress-related genes in cumulus cells (CCs) from smoking and non-smoking women undergoing IVF techniques. Real time PCR technology was used to analyze the gene expression profile of 88 oxidative stress genes enclosed in a 96-well plate array. Statistical significance was assessed by one-way ANOVA. The biological functions and networks/pathways of modulated genes were evidenced by ingenuity pathway analysis software. Promoter methylation analysis was performed by pyrosequencing. Our results showed a down-regulation of 24 genes and an up-regulation of 2 genes (IL6 and SOD2, respectively) involved in defense against oxidative damage, cell cycle regulation, as well as inflammation in CCs from smoking women. IL-6 lower promoter methylation was found in CCs of the smokers group. In conclusion, the disclosed overall downregulation suggests an oxidant-antioxidant imbalance in CCs triggered by cigarette smoking exposure. This evidence adds a piece to the puzzle of the molecular basis of female reproduction and could help underlay the importance of antioxidant treatments for smoking women undergoing IVF protocols.

Abstract
The present study aims to investigate the expression and function of lysine-specific demethylase 4B (KDM4B) in yak cumulus cells (CCs) in order to reveal the mechanisms by which KDM4B regulates biological characteristics and function of CCs. The cellular location of KDM4B and the methylation pattern of H3K9 were detected using immunofluorescence (IF) staining in CCs. The mRNA expression levels of apoptosis-related genes (BCL-2, HAX1 and BAX) and genes related to the estrogen pathway (ESR2, CYP17 and 3B-HSD) were estimated by qRT-PCR after knockdown of KDM4B expression by siRNA in yak CCs. Then, a proliferation assay, Annexin V-FITC staining, and ELISA were utilized to explore the effects of KDM4B silencing on CCs proliferation, apoptosis, and estrogen (E2) secretion, respectively. The results showed that KDM4B is located in the nuclei of yak CCs and is distributed in a dotted pattern. Knockdown KDM4B induced a decrease in cell proliferation, an increase in apoptotic rate and a reduction in the levels of E2 secretion of CCs. Additionally, the methylation patterns of H3K9me2 and H3K9me3 were significantly increased in CCs transfected with KDM4B siRNA-1 (P < 0.05). The mRNA expression level of apoptosis promoting BAX genes was significantly upregulated, but 3B-HSD, ESR2 and anti-apoptotic HAX1 genes were significantly downregulated in transfected CCs (P < 0.05). Furthermore, the rate of embryos developing from the 2-cell stage to blastocysts was lower in the siRNA-1 transfection group than that of the control group (28.6 ± 2.9% vs 40.4 ± 2.4%, P < 0.05). In conclusion, our study indicates that KDM4B regulates the biological characteristics and physiological function of yak CCs mainly through changing the methylation patterns of H3K9 and related gene expression levels.

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.

Abstract
Background Cell banking of initial outgrowths from newly derived human embryonic stem cells (hESCs) requires an efficient freezing method. Vitrification is used for the preservation of gametes and early embryos in assisted reproduction techniques (ART). Moreover, vitrification was applied for cryopreservation of hESCs using open pulled straws. Objective To derive and characterize new hESC lines and then use Cryotech and Cryowin tools for their vitrification. Materials and Methods Human ESC lines were generated in a microdrop culture system using mouse embryonic fibroblasts (MEFs) as the feeder layer; this was later scaled up using both MEFs and Yazd human foreskin fibroblasts batch 8 (YhFF#8). To bank the cell lines, master cell banks of 100 Cryotech and Cryowin tools were produced for each individual cell line using the vitrification method; flasks of hESC lines were also cryopreserved using a conventional slow-freezing method. Results The pluripotency of cell lines was assessed by their expression of pluripotency-associated genes (OCT4/POU5F1, NANOG, and SOX2) and markers such as SSEA4, TRA-1-60, and TRA-2-49. Their in vitro capacity to differentiate into germ layers and germ cells using embryoid body (EB) formation and monolayer culture was assessed by screening the expression of differentiation-associated genes. The chromosomal constitution of each hESC line was assessed by G-banding karyotyping. Conclusion Cryotech and Cryowin tools used to vitrify new hESCs at an early stage of derivation is an efficient method of preserving hESCs.

Abstract
The mammalian ovary is a highly dynamic organ, in which proliferation and differentiation occur constantly during the entire life span, particularly in camels that are characterized by a follicular wave pattern and induced ovulation. Granulosa cells are the main cells of mature follicles. Two distinct cell types, namely, the mural and cumulus granulosa cells are distinguished on the basis of antral fluid increase. The multipotency of follicular fluid and the luteinizing cell were recently demonstrated. However, reports regarding the plasticity of cumulus cells are lacking. We obtained cumulus cells from cumulus-oocyte complexes and showed that camel cumulus cells expressed stem cell mRNA transcripts (POU5A1, KLF4, SOX2, and MYC) and were able to differentiate into other non-ovarian follicular cell types in vitro, such as neurons, osteoblasts, and adipocytes. In contrast, removal of the ooplasm (oocytectemy) showed no effect on cumulus cell proliferation and differentiation. This is the first report to identify an invaluable source of multipotent stem cells, which is routinely discarded during in vitro embryo production. The plasticity and transdifferentiation capability of camel cumulus cells definitely requires attention as it provides a cheap biological experimental model for basic research in stem cells and for understanding ovarian differentiation, both of which are relevant for use in regenerative medicine and tissue engineering in humans and animals.

Abstract
Polycystic ovary syndrome (PCOS) is a common frequent endocrine disorder among women of reproductive age. Although assisted reproductive techniques (ARTs) are used to address subfertility in PCOS women, their effectiveness is not clear. Our aim was to compare transcriptomic profiles of oocytes and cumulus cells (CCs) between women with and without PCOS, and assess the effectiveness of ARTs in treating PCOS patients. We collected oocytes and CCs from 16 patients with and without PCOS patients to categorize them into 6 groups according to oocyte nuclear maturation. Transcriptional gene expression of oocyte and CCs was determined via single-cell RNA sequencing. The ratio of fertilization and cleavage was higher in PCOS patients than in non-PCOS patients undergoing ARTs, and there was no difference in the number of high-quality embryos between the groups. Differentially expressed genes including PPP2R1A, PDGFRA, EGFR, GJA1, PTGS2, TNFAIP6, TGF-β1, CAV1, INHBB et al. were investigated as potential causes of PCOS oocytes and CCs disorder at early stages, but their expression returned to the normal level at the metaphase II (MII) stage via ARTs. In conclusion, ARTs can improve the quality of cumulus-oocyte complex (COC) and increase the ratio of fertilization and cleavage in PCOS women.
