Abstract
In mammals, activation of primordial follicles to primary follicle is a progressive and highly regulated process. There is evidence in mice that phosphatase and tensin homologue deleted on Chromosome 10 (PTEN) silencing is an important negative regulator of phosphatidylinositol 3-kinase (PI3K), which initiates activation of dormant follicles. The objective of the study was to evaluate the effect of the addition of PTEN inhibitor (bpV(HOpic)) (10 μM) and/or Kit Ligand (KL) (100 ng/mL) on the in vitro activation and survival of alpaca primordial follicles. Ovarian cortical fragments from 11 adult alpacas were cultured for 24 h in tissue culture medium (α-MEM+ ) supplemented with KL and bpV or the association of both. Subsequently, each sample was processed by classical histology and follicular counting and classification were performed. The results obtained show a reduction (p < 0.05) of primordial follicles in more than 50% in follicular tissue cultured in vitro in α-MEM+ or supplemented with bpV and/or KL versus the control (not cultured). Further, >25% increase in primary follicles in follicular tissue cultured in vitro in α-MEM+ or supplemented with KL and/or bpV versus control. However, the follicular survival rate showed a decrease of 20% in the cultured tissues, except for the α-MEM+ supplemented with KL and bpV. In conclusion, supplementation of bpV (HOpic) (10 μM) and KL (100 ng/mL) increased the activation in vitro of primordial follicles and survival after in vitro culture of alpaca ovarian tissue.

Abstract
BACKGROUND Chlorogenic acid (CGA) is one of the well-known polyphenol compounds possessing several important biological and therapeutic functions. In order to optimize a culture system to achieve complete development of follicles, we focused on the effects of CGA supplementation during in vitro culture (IVC) on follicular development, oxidative stress, antioxidant capacity, developmental gene expression, and functional potential in cultured mouse ovarian tissue. METHODS AND RESULTS The collected whole murine ovaries were randomly divided into four groups: (1) non-cultured group (control 1) with 7-day-old mouse ovaries, (2) non-cultured group (control 2) with 14-day-old mouse ovaries, (3) cultured group (experimental 1) with the culture plates containing only the basic culture medium, (4) cultured group (experimental 2) with the culture plates containing basic culture medium + CGA (50, 100 and 200 µmol/L CGA). Afterward, histological evaluation, biochemical analyses, the expression assessment of genes related to follicular development and apoptosis as well as the analysis of 17-β-estradiol were performed. The results showed that supplementation of ovarian tissue with the basic culture media using CGA (100 µmol/l) significantly increased the survival, developmental and functional potential of follicles in whole mouse ovarian tissues after 7 days of culture. Furthermore, CGA (100 µmol/L) attenuated oxidative damage and enhanced the concentration of antioxidant capacity along with developmental gene expression. CONCLUSION It seems that supplementation of ovarian tissue with culture media using CGA could optimize follicular growth and development in the culture system.

The combination of basic fibroblast growth factor and kit ligand promotes the proliferation, activity and steroidogenesis of granulosa cells during human ovarian cortical culture.

[PMID: 32871128 DOI: 10.1016/j.cryobiol.2020.08.011] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2020] [Revised: 08/04/2020] [Accepted: 08/26/2020] [Indexed: 12/22/2022]
Abstract
Different factors, such as basic fibroblast growth factor (bFGF) and kit ligand (KL), are used in ovarian cortical culture to promote activation of primordial follicles. In the present study, the effects of bFGF and KL, alone and in combination, were evaluated on human follicular activation and growth during in-situ cortical culture. Slow frozen-thawed human ovarian cortical tissues (n = 6) were cultured in 4 different groups: 1) control (base medium), 2) KL (base medium; BM + 100 ng/ml KL), 3) bFGF (BM + 100 ng/ml bFGF) and 4) bFGF + KL (BM + 100 ng/ml KL + 100 ng/ml bFGF) for a week. The proportion of morphologically normal and degenerated follicles at different developmental stages, secreted hormonal levels and specific gene expressions were compared. Although the proportion of growing follicles was higher than primordial counterpart in all cultured groups, no significant differences were observed among the cultured groups. In all cultured groups, anti-Müllerian hormone (AMH), progesterone and estradiol hormones levels increased after 7 days of culture; however, this increase was only significant for estradiol in the bFGF + KL group. The expression of Ki67 gene indicated an increase in ovarian cell proliferation in the three experimental groups compared to the control group, however this increment was only significant for the bFGF + KL group. It can be concluded that KL and bFGF factors individually have no beneficial effects on in-situ follicular growth, but their combination positively influences steroidogenesis of granulosa cells without significantly increasing the number of growing follicles.

Abstract
This study aimed to evaluate different vitrification methods using distinct cryoprotectants (CPAs) for the preservation of collared peccary ovarian preantral follicles (PFs). Ovarian pairs from six females were fragmented and three fragments (fresh control group) were immediately evaluated for morphology, viability, cell proliferation capacity (assessed by quantifying the number of argyrophilic nucleolus organizer regions - NORs), and apoptosis (by the identification of activated caspase-3 expression). The remaining 18 fragments were vitrified using the solid surface vitrification (SSV) method or the ovarian tissue cryosystem (OTC) with 3 M ethylene glycol (EG), 3 M dimethylsulfoxide (DMSO), or a combination of the two (1.5 M EG/1.5 M DMSO). After two weeks, samples were rewarmed and evaluated as described previously. The OTC with any of the CPAs provided a similar conservation of morphologically normal PFs as the fresh control group (75.6 ± 8.6%); however, the SSV was only efficient with DMSO alone (63.9 ± 7.6%). Regarding the viability or cell proliferation, all tested groups provided post rewarming values similar to those observed for the fresh control group, 84.0 ± 2.9% viable cells with 2.0 ± 0.2 NORs. Related to apoptosis analysis, only the OTC with EG (46.7%) and the SSV method with EG (43.4%) or the combination of EG and DMSO (33.4%) provided similar values to those found for the fresh control group (36.7%). Our findings indicate the utilization of a closed system, the OTC, with 3 M EG as the CPA for the vitrification of collared peccary ovarian tissue.

Abstract
Most of the mammalian follicles undergo a degenerative process called “follicle atresia”. Apoptosis of granulosa cells is the main characteristic of follicle atresia. Follicle stimulating hormone (FSH) and the transforming growth factor β (TGF-β) superfamily have important regulatory functions in this process. FSH activates protein kinase A and cooperating with insulin receptor substrates, it promotes the PI3K/Akt pathway which weakens apoptosis. Both Smad or non-Smad signaling of the transforming growth factor β superfamily seem to be related to follicle atresia, and the effect of several important family members on follicle atresia is concluded in this article. FSH and TGF-β are likely to mutually influence each other and what we have already known about the possible underlying molecular mechanism is also discussed below.

Abstract
AIM To evaluate the mitochondrial DNA (mtDNA) copy number, reactive oxygen species (ROS) level and intensity of mitochondrial enzyme activity in metaphase II oocytes derived from vitrified cultured immature mouse ovarian tissue in comparison with nonvitrified group and in vivo-obtained oocytes. METHODS Vitrified and nonvitrified ovaries from neonate female mice were cultured for 7 days. Then, preantral follicles were isolated and cultured in a three-dimensional culture system. Follicular development and oocyte maturation were evaluated and compared in both groups. Some of the collected metaphase II oocytes derived from in vitro and in vivo conditions were inseminated with capacitated spermatozoa, and then, the fertilization and embryo developmental rates were assessed. In the other series of oocytes, mtDNA copy number, distribution and enzyme activity and ROS level were analyzed. RESULTS The embryo development, mtDNA copy number and mitochondrial enzyme activity in collected metaphase II oocytes from two in vitro-cultured groups were significantly lower, and the ROS level was higher than those of the in vivo group (P < 0.05), but there was no significant difference between vitrified and nonvitrified groups. CONCLUSION This study showed that a two-step in vitro culture of mouse ovarian tissue decreased the mtDNA copy number and cytochrome c oxidase activity of metaphase II oocytes through an increase in their ROS level in comparison with in vivo-obtained oocytes. Thus, the in vitro culture methods should be improved.

Abstract
The aim of this study was to evaluate the effects of ovarian tissue vitrification and two-step in vitro culture on the metaphase II (MII) oocyte reactive oxygen species (ROS) level, mitochondrial transcription factor A (TFAM) expression and succinate dehydrogenase (SDH) activity. After collection of neonatal mouse ovaries, 45 ovaries were vitrified and the others (n = 45) were considered as control. All ovaries were cultured for seven days, and their isolated preantral follicles were cultured in three-dimensional culture system. After 12 days, the follicular development and oocyte maturation were evaluated and compared in vitrified and non-vitrified ovaries. The collected MII oocytes were inseminated with capacitated spermatozoa. Then, the fertilization, embryonic development, ROS level, TFAM gene expression and SDH activity of oocytes were assessed and compared. There was no significant difference between morphology and percentage of normal follicles between vitrified and non-vitrified ovaries at the beginning of culture. The follicular development and hormone level in the vitrified group was significantly lower than non-vitrified group and the ROS concentration in the vitrified group was significantly higher than non-vitrified group after one-week culture. After follicular culture, there was no significant difference in follicular development, oocyte maturation, fertilization rate, TFAM gene expression, ROS level and mitochondrial SDH activity between the groups. This study showed that ovarian tissue vitrification influences the follicular development through increase in ROS level during culture but these harmful effects may be recovered during the follicular culture period. Thus, vitrification and ovarian culture method should be improved.

The Effects of Lysophosphatidic Acid on The Incidence of Cell Death in Cultured Vitrified and Non-Vitrified Mouse Ovarian Tissue: Separation of Necrosis and Apoptosis Border. CELL JOURNAL 2018; 20:403-411.

Abstract
Objective The aim of the present study was to examine whether lysophosphatidic acid (LPA) could decrease cell death and improve in vitro culture (IVC) conditions in cultured vitrified mouse ovarian tissue. Materials and Methods In this experimental study, we collected and randomly divided 7-day-old mouse ovarian tissues into vitrified and non-vitrified groups. The ovaries were cultured in the presence and absence of LPA for one week. Morphology and follicular development were evaluated by hematoxylin and eosin (H&E) and Masson's trichrome (MTC) staining. The incidence of cell death was assessed by flow cytometry using annexin V/propidium iodide (PI) and a caspase-3/7 assay in all studied groups. Results The vitrified groups had a significantly decreased follicle developmental rate compared to the non-vitrified groups (P<0.05). Overall, qualitative and quantitative results showed prominent follicular degeneration in the vitrified groups compared with the respective non-vitrified groups. Both LPA treated groups had a significantly higher proportion of preantral follicles compared to the non-LPA treated groups (P<0.05). Flow cytometry analysis results showed significantly greater early and late apoptotic cells in all groups (17.83 ± 8.80%) compared to necrotic cells (7.97 ± 0.92%, P<0.05). The percentage of these cells significantly increased in the vitrified groups compared with non-vitrified groups. LPA treated groups had a lower percentage of these cells compared to non-LPA treated groups (P<0.05). The lower enzyme activity was observed in non-vitrified (especially in the LPA+ groups) cultured ovaries compared to the vitrified group (P<0.05). Conclusion Both vitrification and IVC adversely affected cell survival and caused cell death. We postulated that LPA supplementation of culture medium could improve the developmental rate of follicles and act as an anti-cell death factor in non-vitrified and vitrified ovarian tissues. It could be used for in vitro maturation of ovarian tissue.

Abstract
Objective This study aimed to evaluate the expression of the genes related to folliculo-genesis after vitrification of mouse ovarian tissues using a two-step in vitro culture.
Materials and Methods In this experimental study, vitrified and non-vitrified ovaries from
7- day old (neonate) female mice were cultured using alpha-Minimum Essential Medium
(α-MEM) supplemented with 5% fetal bovine serum (FBS) for 7 days. Morphology, surface
area of ovaries and percentage of normal follicles were evaluated and compared in both
groups. After one-week culture, in non-vitrified group, preantral follicles of cultured ovaries
were isolated and cultured in a three-dimensional alginate culture system for 12 days.
Then, the collected metaphase (M) II oocytes were inseminated with capacitated spermatozoa derived from 7-8-week old (adult) male NMRI mice. Follicular diameter, oocyte maturation, fertilization, embryo development and the expression of genes related to follicular
development (Pcna, Fshr and Cyp17a1,) using real time reverse transcription-polymerase
chain reaction (RT-PCR) were assessed at the end of last culture period in both groups.
Results The ovarian area in vitrified group (162468.20 703.78) was less than non-vitrified
group (297211.40 6671.71), while the percentage of preantral follicles in vitrified group
(18.40%) was significantly lower than those of non-vitrified group (24.50%) on day 7 of
culture (P<0.05). There were no significant differences between the two groups in terms of
follicular diameter, expression of genes related to development of follicles, oocyte maturation, fertilization, as well as embryo development (P>0.05).
Conclusion The results of this study showed that vitrification of ovarian tissue following
in vitro culture had negative impact on the survival and development of follicles within the
tissue. However, no significant alterations were observed in development, gene expression and hormonal production of in vitro culture of isolated follicles derived from vitrified
ovarian tissues as compared to the non-vitrified samples.

Abstract
Ovarian cryopreservation by vitrification is a highly useful method for preserving female fertility during radiotherapy and chemotherapy. However, cryoinjury, osmotic stress during vitrification, and ischemia/reperfusion during transplantation lead to loss of ovarian follicles. Ovarian follicle loss may be partially reduced by several methods; however, studies regarding the mechanism of ovarian follicle loss have only investigated cell apoptosis, which consists of type I programmed cell death. Autophagy is type II programmed cell death, and cell homeostasis is maintained by autophagy during conditions of stress. The role of autophagy during cryopreservation by vitrification has rarely been reported. The potential role of autophagy during ovarian cryopreservation by vitrification is reviewed in this article.
