Among commercially available urinary human menopausal gonadotrophin (HMG) material, gonadotrophins comprise <5% of the total protein content. Thus, during a typical ovarian stimulation cycle with HMG, several milligrams of non-relevant proteins are administered that may lead to unwanted side effects, including allergic or other hypersensitivity reactions. The effects of two recombinant and four...
A series of experiments were conducted to evaluate the effects of FSH supplementation during IVM on porcine oocyte nuclear maturation, and subsequent fertilization, cleavage and embryo development. Cumulus-oocyte complexes (COCs) were cultured 40 h without FSH (control), 40 h with FSH (FSH 0-40 h), or 20 h with FSH followed by a 20-h culture period without FSH (FSH 0-20 h). Nuclear stage of ooc...
A sequential medium was evaluated on the survival, activation and growth rates of caprine preantral follicles submitted to a long-term culture period, aiming to establish an ideal in vitro culture system. Ovarian fragments were cultured for 16 days in α-MEM(+) alone or supplemented with hormones (GH and/or FSH) added sequentially on different days of culture. Ovarian fragments were cultured in ...
BACKGROUND The follicle-stimulating hormone receptor (FSH-R) is a seven transmembrane spanning receptor (7TMR) which plays a crucial role in male and female reproduction. Upon FSH stimulation, the FSH-R activates the extracellular signal-regulated kinases (ERK). However, the mechanisms whereby the agonist-stimulated FSH-R activates ERK are poorly understood. In order to activate ERK, some 7 TMR...
Sex hormones regulate cholangiocyte hyperplasia in bile duct-ligated (BDL) rats. We studied whether follicle-stimulating hormone (FSH) regulates cholangiocyte proliferation. FSH receptor (FSHR) and FSH expression was evaluated in liver sections, purified cholangiocytes, and cholangiocyte cultures (NRICC). In vivo, normal female and male rats were treated with FSH or immediately after BDL with a...
در مطالعه حاضر اثرات تزریق گنادوتروپین سرم مادیان آبستن (pmsg) به همراه هورمون محرک رشد فولیکولی (fsh) و هورمون آزادکننده گنادوتروپین (gnrh) بر رشد فولیکولی و برهزایی میشهای نژاد افشاری مورد بررسی قرار گرفت. چرخه فحلی 80 راس میش نژاد افشاری چندشکم با میانگین وزنی 5/2± 68 و bcs 5/3-5/2، با استفاده از سیدرهای پروژسترونی 14 روزه همزمان سازی شد. 400 واحد از گنادوتروپین سرم مادیان آبستن (pmsg) همز...
Transcripts and protein for follicle-stimulating hormone receptor (FSHR) were demonstrated in abdominal adipose tissue of female chickens. There was no expression of the Fsh gene, but FSH and FSHR colocalized, suggesting that FSH was receptor bound. Partial correlations indicted that changes in abdominal fat (AF) content were most directly correlated with Fshr mRNA expression, and the latter wa...
هورمون محرک فولیکول گاوی (fsh) به خانواده هورمون های گلیکوپروتئینی تعلق دارد که از غده هیپوفیز یا جفت ترشح می شوند. این هورمون یک هترو دایمر می باشد که از زیر واحد آلفا (مشترک در همه هورمون های گلیکوپروتئینی) و زیر واحد بتا (اختصاصی هر هورمون) تشکیل شده است. fsh گاوی در تکنولوژی تولید مثل، مانند سوپراوولاسیون حیوانات مزرعه ای و درمان سندرم پلی سیستیک تخمدان استفاده می شود. همچنین این هورمون برا...
It is currently admitted that Follicle-Stimulating Hormone (FSH) is physiologically involved in the development and function of fetal/neonatal Sertoli cells in the rat but not the mouse. However, FSH is produced by both species from late fetal life onwards. We thus reinvestigated the role of FSH in mouse testis development at day 0 (birth) 6, 8 and 10 post-partum (dpp) by using mice that lack f...
