BACKGROUND Ovarian tissue cryopreservation is an alternative strategy to preserve the fertility of women predicted to undergo premature ovarian failure. This study was designed to evaluate the expression of folliculogenesis-related genes, including factor in the germline alpha (FIGLA), growth differentiation factor-9 (GDF-9), follicle-stimulating hormone receptor (FSHR), and KIT LIGAND after vi...
The epithelial ovarian carcinomas, which make up more than 85% of human ovarian cancer, arise in the ovarian surface epithelium (OSE). The etiology and early events in the progression of these carcinomas are among the least understood of all major human malignancies because there are no appropriate animal models, and because methods to culture OSE have become available only recently. The object...
background isolation of adipose tissue mesenchymal stem cells (mscs) with current enzymatic methods has some limitations. for example, it is costly and time-consuming and results in a heterogeneous cell population that making compromise proliferation and differentiation of mscs. also, it is accompanied with the increased risk of culture contaminations because of several handling steps.in this ...

Bleomycin (BLM) as an anti-cancer agent causes tissue toxicities through DNA damaging and cell deaths. The aim of this study was to investigate the effects of thymol against genotoxicity and anti-proliferation induced by BLM in normal human lymphocytes and ovarian cancer cells. Peripheral blood samples were collected from human volunteers and were incubated with thymol at different concentratio...
Immunocytogenetic detection of normal and abnormal oocytes in human fetal ovarian tissue in culture.
This study aimed to: (i) determine whether oocytes are present in cultures of human fetal ovary; (ii) identify whether meiotic anomalies are evident; and (iii) assess whether preparation or culture conditions influence oocyte survival and meiotic progression. Ovaries were collected from fetuses after termination at 13-16 weeks. Oocyte assessment utilized antibodies specific for synaptonemal com...
STUDY QUESTION What is the effect of basic fibroblast growth factor (bFGF) on the growth of individual early human follicles in a three-dimensional (3D) culture system in vitro? SUMMARY ANSWER The addition of 200 ng bFGF/ml improves human early follicle growth, survival and viability during growth in vitro. WHAT IS KNOWN ALREADY It has been demonstrated that bFGF enhances primordial follicl...
