P-83: Development of Mouse Preantral Follicles in Fibrin-Alginate Matrix during In Vitro Culture
نویسندگان
چکیده مقاله:
Background This research was conducted to assess preantral follicle development in fibrin alginate matrix following ovarian tissue vitrification MaterialsAndMethods Ovaries of 13-day-old NMRI female mice were removed and placed in control and vitrification groups. Vitrification group ovaries were transferred in media containing ethylene glycol, dimethyl sulphoxide, and sucrose then were plunged in LN2 by acupuncture needle. Medium sized preantral follicles of fresh control and vitrified-warmed ovaries were mechanically isolated and cultured in fibrin-alginate matrix for 12 days. Finally, survival and growth rate and also quantitative oocyte maturation genes (Gdf9 and Bmp15) expression of follicles were evaluated on 1st and 12th culture days Results Although higher follicle survival rate was shown in control group rather than vitrification one, follicle diameter was being increased until the last culture day in both groups. Quantitative oocyte maturation genes expression evaluation did not reveal any significant difference between control and vitrification groups on first and last days of culture, but they were significantly decreased on 12th culture day compared to the first in both groups Conclusion According to the observed similarities in both groups, it seems that fibrin-alginate could be an appropriate matrix for mouse preantral follicle development and in spite of decreased follicle survival rate in vitrification group, applied vitrification method did not affect developmental competence of ovarian follicles

P-116: Maturation Genes Expression during In Vitro Culture of Vitrified Mouse Preantral Follicles
Background: Evaluation of maturation genes expression and their pattern during in vitro culture of vitrified preantral follicles is an essential and could promote either vitrification procedure or culture condition. Materials and Methods: Preantral follicles (with 100- 130 μm diameter) isolated mechanically from 12-14 days old NMRI mice ovaries and divided into vitrification and control groups....

Background: Cryopreservation of oocytes is an effective technology in assisted reproductive technology. Although successful vitrification of gametes has been reported in several mammalian species, the survival is generally low. The aim of this study was to investigate the effects of fibroblast growth factor (FGF) and hepatocyte growth factor (HGF) on preantral follicle development after vitrifi...

Background: In vitro culture (IVC) of isolated preantral follicles from cryopreserved ovarian tissue might be an efficient method for enhancing mature oocytes in patients who are exposed to infertility. Materials and Methods: Ovaries of 13-day old NMRI mice were removed and randomly placed into control,needle immersed (NIV) and solid surface vitrification (SSV) groups. For vitrification, ovarie...

Objective In the present study, the effects of alginate (ALG) concentration and ovarian cells (OCs) on the development and function of follicles were simultaneously evaluated. MaterialsAndMethods In the first step, preantral follicles (100-130 µm in diameter) were mechanically isolated from the ovaries of 2-week-old NMRI mice, encapsulated in the absence or presence of OCs in 0.5, 0.75 and 1% A...
