Effects of umbilical cord mesenchymal stem cells on expression of CYR61, FSH and AMH in mice with premature ovarian failure

The aim of this study was to objective to investigate the effects of umbilical cord mesenchymal stem cells on the expression of CYR61, FSH and AMH in mice with premature ovarian failure. For this purpose, thirty SPF female SD mice were selected as the research object, 10 of which were control group, namely group α, and 20 mice with premature ovarian failure model were established by cyclophosphamide. The mice were divided into model group, namely β group and the umbilical cord mesenchymal stem cell transplantation group (γ group), with 10 mice in each group. ELSA method was used to determine the levels of follicle-stimulating hormone (FSH), Luteinizing hormone (LH), estradiol (Estradiol) in serum. The changes of E2, Antimullerian hormone (AMH) and cysteine-rich protein 61 in ovarian tissues were determined by the protein imprinting method. Connective tissue growth factor (CTGF) and caspase-3 protein expression. Results showed that in fertility rate, γ group > α group > β group, the difference was statistically significant (P<0.05), in litter size, α group > γ group > β group, the difference was statistically significant (P<0.05). The levels of serum E2 and AMH in α group > γ group > β group, and the levels of serum FSH and LH in β group > γ group > α group were statistically significant (P<0.05). The growth follicles were α group > γ group > β group, and the atresia follicles were β group > γ group > α group, and there was a statistical difference among all groups (P<0.05). There was no difference in luteal number among the three groups (P>0.05). In terms of CYR61 and CTGF protein expression, α group > γ group > β group, and in terms of caspase-3, β group > γ group > α group had statistical significance (P<0.05). It is concluded that intervention with umbilical cord mesenchymal stem cells can significantly improve the expression levels of CYR61 and AMH, reduce the level of FSH, promote cell survival, improve the reproductive quality of mice, and restore the physiological function of the ovary. It is feasible to treat premature ovarian failure with umbilical cord mesenchymal stem cells.

Blood supply to the uterus and ovaries in healthy women and patients with ovarian insufficiency

The aim of this study was to investigate the relation between ovarian blood flow, folliculogenesis and sex-steroid production during normal menstrual cycle and in women with ovarian failure. Ten healthy women and 40 patients with ovarian failure underwent hormonal assays (follicle-stimulating, luteinizing hormones, estradiol, progesterone, prolactine, testosterone) and ultrasound examination of the uterus and ovaries with color Doppler ultrasonography of the uterine and ovarian vessels on the 3 -5th, 11- 13th, 17- 19th and 21 -23rd days оf menstrual cycle. Intraovarian blood flow of the ovary carrying the predominant follicle in healthy women appeared more active than in conrdlateral ovary on the 3-5th days of the cycle. Inpatients with ovarian failure no difference was detected between the ovaries during the periods in question. Ovarian and uterine blood flow inpatients with the ovarian failure was less intensive comparingwith healthy women. Positive correlation between uterine blood flow and estradiol concentration in serum was revealed.

Peritoneal endometriosis and infertility

Peritoneal endometriosis and infertility in most of patients (in 80%) are pathogenetically conjugated. Both peritoneal endometriosis and infertility are based in ovarian failure. These women have a low endometrial receptivity for blastocysts implantation (retardation development of glands, vessels, and stroma; changes in the microrelief of the epithelium). Even at the beginning of the menstruation patients with peritoneal endometriosis and infertility have cells with a great adhesive and proliferative potential in the endometrium. This kind of cells have an ability for long autonomous existence. Ovarian failure in these women is a promotion factor for development of the retrograde menstruation. In these conditions the endometrial cells with adhesive potential are frequently bringing in the abdominal cavity. Active endometrium heterotopias support the ovarian failure and create conditions for uterine infertility (implantation disorders).

Late Endocrine Effects after Stem Cell Transplant in a Young Girl with Griscelli Syndrome

Background. Griscelli syndrome (GS) is a rare disorder characterized by partial albinism and silver hair with alteration in genes necessary for melanin transport. Type 2 GS is fatal due to severe immunodeficiency without curative stem cell transplant (SCT). Late endocrinopathies are quite common in other disorders after SCT. These complications have not been reported in GS. Case Presentation. A 7-year-old female presented for growth failure with a history of GS status post curative SCT and consequently developed graft-versus-host disease (GvHD). She also had a history of eosinophilic enterocolitis, for which she was taking supraphysiologic glucocorticoids for the past year. She presented with severe short stature along with mild hyperthyroxinemia with subsequent diagnosis of Graves’ disease, which was treated with methimazole. GH therapy was commenced due to persistent growth failure, with a robust increase in growth parameters. She started spontaneous puberty; however, initial biochemical evaluation revealed hypergonadotropic hypogonadism with undetectable anti-Mullerian hormone (AMH) consistent with low ovarian reserve and premature ovarian failure. Discussion. Growth failure was multifactorial due to her inflammatory condition and poor weight gain from multiple underlying illnesses, including hyperthyroidism, as well as chronic supraphysiologic glucocorticoid use. Although hypothyroidism is more commonly seen after SCT, rare cases of hyperthyroidism have been reported. In addition to SCTs, GvHD and GS have been associated with autoimmune conditions. It is important to monitor pubertal progression as the majority of those treated with alkylating agents prior to SCT have pubertal and ovarian failure and remain at risk for premature menopause.

Incidence of amenorrhea and premature ovarian failure in women who underwent uterine fibroid embolization: single centre study

Purpose: To retrospectively determine the incidence of amenorrhea and premature ovarian failure in women who underwent uterine fibroid embolization (UFE) in King Fahad Specialist Hospital in Dammam (KFSH-D). Patients and methods: All women who had undergone UFE in KFSH-D from August 2007 to October 2015 were included for a total of 82 patients. Follow up consisted of a questionnaire inquiring about symptoms, improvement after the procedure and whether menstruation resumed or not. The pre-procedure and post-procedure pelvis MRI as well as UFE images and reports were reviewed for all patients. Results: One patient (1.5 %) was found to have amenorrhea out of the 67 patients we were able to contact. She was 52 years old at the time of UFE and had irregular period. Menstruation did not resume following UFE along with menopausal symptoms including night sweats, mood swings and irritability, likely due to premature ovarian failure (POF). The rest of patients had normal resumption of menses. Conclusion: The incidence of amenorrhea is less than what’s reported in the literature could be due to advances in UFE since its introduction as a treatment for uterine fibroids, likely due to advances in image quality, tans-catheter embolization equipments/techniques and embolic material used in UFE.

Assessment of risk factors and prediction of premature ovarian failure

The problem of premature ovarian failure (POF) is currently in the spotlight of obstetricians and gynecologists worldwide. Early diagnosis of this pathology is necessary to prevent the development of serious pathological conditions. The systematization of modern ideas about laboratory and instrumental methods for POF diagnosing, assessing diagnostic value of parameters such as follicle stimulating hormone, anti-Mullerian hormone as well as the count of antral ovarian follicles, intraovarian blood flow and ovarian volume using ultrasound techniques, which can then be used as prognostic criteria for POF comprise a very important modality. Based on the findings obtained, early detection may lead to proposing new prognostic strategies.

Research Progress on the Treatment of Premature Ovarian Failure Using Mesenchymal Stem Cells: A Literature Review

Premature ovarian failure (POF) has become one of the main causes of infertility in women of childbearing age and the incidence of POF is increasing year by year, seriously affecting the physical and mental health of patients and increasing the economic burden on families and society as a whole. The etiology and pathogenesis of POF are complex and not very clear at present. Currently, hormone replacement therapy is mainly used to improve the symptoms of low estrogen, but cannot fundamentally solve the fertility problem. In recent years, stem cell (SC) transplantation has become one of the research hotspots in the treatment of POF. The results from animal experiments bring hope for the recovery of ovarian function and fertility in patients with POF. In this article, we searched the published literature between 2000 and 2020 from the PubMed database (https://pubmed.ncbi.nlm.nih.gov), and summarized the preclinical research data and possible therapeutic mechanism of mesenchymal stem cells (MSCs) in the treatment of POF. Our aim is to provide useful information for understanding POF and reference for follow-up research and treatment of POF.
