Growth differentiation factor-9 (GDF-9) is a transforming growth factor-b (TGF-b) family member which is expressed in the oocytes in mouse ovaries (McGrath, S.A., Esquela, A.F., Lee, S.J., 1995. Oocyte-specific expression of growth/differentiation factor-9. Mol. Endocrinol. 9, 131-136). GDF-9 is indispensable for normal folliculogenesis since female mice deficient for the GDF-9 gene are inferti...

Growth differentiation factor 9 (GDF-9) is a transforming growth factor-beta family member that is required for normal folliculogenesis in female mice, but its role as a regulator of human fertility is still unclear. We determined here by in situ hybridization and immunohistochemical analyses the localization of the GDF-9 messenger ribonucleic acid (mRNA) and protein during human folliculogenes...

Background: Growth differentiation factor -9B (GDF-9B) is an oocyte derived growth factor, this protein is essential for development of ovarian follicles and act mainly by binding to its receptor on the surface of granulosa cells. The effect of this factor on the growth of follicles in various developmental stages particularly primordial and primary follicles is unknown. The aim of this study w...

Background The conventional freezing and vitrification are different cryopreservation protocols for fertility preservation in cancer patients. The high effectiveness of vitrification for human oocytes and embryos is shown, whereas data on human ovarian tissue are limited. Follicular growth, ultrastructure, and apoptosis incidence in human ovarian tissue following vitrification/warming and after...

مقدمه: عامل رشدی تمایزی- b9 ( gdf-9b) یک فاکتور رشد پروتئینی مشتق از تخمک است که در تکوین فولیکول های تخمدان ضروری است، این فاکتور عمدتا بواسطه رسپتور خود بر سطح سلول های گرانولوزا اثر خود را اعمال می کند. اثر gdf-9b بر فولیکول های مراحل مختلف تکوینی بویژه فولیکول های بدوی و اولیه نا مشخص است. هدف از این مطالعه بررسی اثر gdf-9b بر رشد فولیکول های مراحل مختلف تکوینی، بیان ژن شاخص آنتی ژن تکثیر ...

مقدمه: با توجه به نبود گزارشی مبنی بر ارزیابی رشد فولیکولی، فراساختار و وقوع آپوپتوز در بافت تخمدانی انسانی منجمد/ذوب شده در دو مرحله پس از ذوب و پس از کشت در حضور فاکتورهای gdf-9b و یا هدف از این پژوهش ارزیابی آنها برای اولین بار بود. مواد و روشها: بیوپسیهای بافت تخمدان از زنان نرمال تحت عمل سزارین جمع آوری شد و در دو گروه انجماد شیشه ای و غیر انجمادی تقسیم بندی شدند. پس از انجام مراحل انج...

Background The high effectiveness of vitrification, as a cryopreservation protocol, for human oocytes and embryos is shown, whereas data on human ovarian tissue are limited. This study aimed to assessment of follicular growth, ultrastructure, and apoptosis incidence in human ovarian tissue following vitrification/warming and after culture in the presence of LIF.

Growth differentiation factor-9 (GDF-9) is a family member of bone morphogenetic proteins (BMPs), which belong to the TGF-β superfamily. There has been a recent surge of interest in the role of growth differentiation factors and other BMPs in the development and spread of cancer. However, the role of GDF-9 in bladder cancer remains unknown. The present study investigated the expression of GDF-9...

PURPOSE Growth and differentiation factor (GDF)-15 is a member of the transforming growth factor (TGF)-beta family. GDF-15 is necessary for the maintenance of pregnancy but has also been linked to other physiologic and pathologic conditions. EXPERIMENTAL DESIGN The expression of GDF-15 in glioma cell lines was assessed by quantitative reverse transcriptase-PCR and immunoblot. GDF-15 levels in...
