Cardiovascular disease, rare in premenopausal women, increases sharply at menopause and is typically accompanied by chronic inflammation. Previous work in our laboratory demonstrated that replacing senescent ovaries in post-reproductive mice with young, actively cycling ovaries restored many health benefits, including decreased cardiomyopathy and restoration of immune function. Our objective here was to determine if depletion of germ cells from young transplanted ovaries would alter the ovarian-dependent extension of life and health span...

BACKGROUND: Many studies have reported that inflammation and oxidative stress are involved in the pathogenesis of polycystic ovary syndrome (PCOS). Bone marrow mesenchymal stromal cells (BM-MSCs) have anti-oxidant and anti-inflammation properties. In this study, we investigate the beneficial effect of stem cell therapy on folliculogenesis in mice with induced PCOS METHODS: Mouse model of PCOS was performed through daily injection of testosterone enanthate (1 mg/100 g/body weight subcutaneous (s...

INTRODUCTION: Treosulfan is an alkylating agent that is used for the treatment of ovarian cancer and for conditioning prior to stem cell transplantation. It is a prodrug that is activated non-enzymatically to two active epoxides. OBJECTIVES: To optimize a protocol for both in vivo samples handling and in vitro drug preparation. Treosulfan stability was tested in biological fluids at different conditions as well as for its cytotoxicity on cell lines. RESULTS: Plasma samples can be safely frozen for a short period up to 8h, however; for longer periods, samples should be acidified...

The use of secretome may be a new strand of cell therapy, which is equal to or even superior to the injection of live cells, called cell-free therapy. In ovarian transplantation, this approach may be a therapeutic possibility for the ovarian graft in hypoxia. We designed the present study to evaluate whether the cell-free therapy with the secretome of adipose tissue-derived stem cells (ASCs) in rat frozen-thawed ovarian grafts could protect a graft against ischemic injury. A single dose of rat ASCs secretome or vehicle was injected into the bilateral frozen-thawed ovaries of 18 adult female rats immediately after an autologous transplant...

SummaryOvarian biopsies from five health adult monkeys were collected by exploratory laparotomy. Preantral follicles (primordial, primary, and secondary) were classified as normal or degenerated and submitted to morphometric analysis in which granulosa cell counts and the areas of follicles, oocytes, and oocyte nuclei were measured. Ovarian fragments were also immunolabelled for the quantitative analysis of VEGFA and CD31 protein expression in the ovarian tissue and in the preantral follicles. In total, 213 preantral follicles was examined for morphometry and morphological classification...

Endometriosis is a prevalent gynecological disorder that eventually gives rise to painful invasive lesions. Increased levels of transforming growth factor-beta1 (TGF-B1) have been reported in endometriosis. However, details of the effects of high TGF-B1 on downstream signaling in ectopic endometrial tissue remain obscure. We induced endometriotic lesions in mice by surgical auto-transplantation of endometrial tissues to the peritoneal regions. We then treated endometriotic (ectopic and eutopic endometrial tissues) and non-endometriotic (only eutopic endometrial tissues) animal groups with either active TGF-B1 or PBS...

Simultaneous pancreas-kidney transplant is the ultimate therapy for patients who have uncontrolled and complicated type 1 diabetes mellitus with end-stage renal disease. The combined pancreas transplant provides a euglycemic milieu for the kidney and protects it from recurrence of diabetic complications. Our patient, a 41-year-old woman with end-stage diabetic nephropathy and history of multiple abdominal surgeries (ovarian cyst fenestration, adnexal extirpation, abdominal wall reconstruction), including urinary diversion (Bricker loop, above double J stent), underwent simultaneous pancreas-kidney transplant...

One of the challenges that must be overcome during ovarian tissue transplantation is Ischaemia/Reperfusion Injury (IRI). The most important hypothesis explaining the cellular events in I/R processes are calcium overload and oxygen free radicals constitute. Here, we study the effect of verapamil on IRI, and consequently on follicle survival during ovarian transplants in an autograft model. Female mice were randomly assigned into three groups in order to ovarian autotransplantation as follow: Group 1 (Control group), Group 2 (Transplanted group) and Groups 3 (Transplanted + Verapamil group)...

For the precision resection, development of near-infrared (NIR) fluorescent probe based on specificity identification tumor-associated enzyme for lighting-up the tumor area, is urgent in the field of diagnosis and treatment. Overexpression of γ-glutamyltranspeptidase, one of the cell-membrane enzymes, known as a biomarker is concerned with the growth and progression of ovarian, liver, colon and breast cancer compared to normal tissue. In this work, a remarkable enzyme-activated NIR fluorescent probe NIR-SN-GGT was proposed and synthesized including two moieties: a NIR dicyanoisophorone core as signal reporter unit; γ-glutamyl group as the specificity identification site...

BACKGROUND: Ovarian tissue autografting is a fertility restoration technique that is frequently used in young women with cancer who undergo radio/chemotherapy. A limiting factor in this technique is ischemia-reperfusion (I/R) damage. Because adipose-derived mesenchymal stromal cells (ADMSCs) protect different ischemic tissues against I/R damage, we examined the effect of ADMSC transplantation at the graft site in mice ovary autografting. METHOD: Mice were divided into three groups: control, autograft and autograft + ADMSCs...

Implantation of ovarian tissue allografts in outbred Wistar rats and inbred August rats against the background of induction of donor-specific tolerance was accompanied by an increase in liver content of mononuclear cells expressing LMP2 immune of proteasome subunit by day 37 after transplantation in comparison with day 0. Graft rejection, on the contrary, was associated with a decrease in the number of LMP2+ cells in the liver of rats of both lines during this period. The difference in the content of these cells and the graft take rate were higher in Wistar rats...

Placenta-derived mesenchymal stem cells (PD-MSCs) have numerous advantages over other adult MSCs that make them an attractive cell source for regenerative medicine. Here, we demonstrate the therapeutic effect of PD-MSCs in ovariectomized (Ovx) rats and compare their efficacy when generated via a conventional monolayer culture system (2D, naïve) and a spheroid culture system (3D, spheroid). PD-MSC transplantation significantly increased the estradiol level in Ovx rats compared with the non-transplantation (NTx) group...

OBJECTIVE: Hormonal changes, in either men or women experiencing chronic kidney disease, cause decreased libido, erectile dysfunction, dysmenorrhea, and ovarian dysfunction, all of which may contribute to infertility. Patients' endocrinal and sexual function could be rapidly restored after successful renal transplantation (RTx), which may assist in achieving a successful pregnancy. However, fetuses will be exposed to the immunosuppressive agents passed on from the female recipients, which may be another potential factor leading to a poor fetal outcome...
