Ultrastructure and viability of isolated bovine preantral follicles.
Techniques for the isolation of ovarian follicles and maturation of oocytes in vitro have enormous reproductive potential. Preservation of normal tissue function is vital. This study emphasizes the ultrastructure and viability of mechanically isolated bovine small (diameter 40-100 microm) preantral and large (140-450 microm) preantral/early antral follicles. Viability studies were performed for...
متن کاملIn vitro culture of goat preantral follicles
Background: The majority of thousands of oocytes in the ovaries are small, non-growing and reside in preantral follicles (PFs). The development of a culture system for preantral follicle may be very useful for understanding the complex mechanism in folliculogenesis at early stages of development as wells as could offer a significant way for the propagation of livestock, including goats. This pa...
متن کاملP-36: The Effect of Lipoic Acid on Developmental Competence of Cultured Isolated Mouse Preantral Follicles
Background: α-Lipoic acid (LA) is a cofactor in mitochondrial multienzyme complexes and is well-known for its antioxidant properties in both of in vivo and in vitro condition. Materials and Methods: Preantral follicles were isolated from 2 weeks old NMRI mice ovaries. LA at concentrations of 0 and 100 μM was supplemented to culture media (α-MEM medium supplemented with 5% FBS, 100 mlU/ml FSH, 1...
متن کاملIn vitro culture of bovine preantral follicles.
Bovine preantral follicles (40-100 microm diameter at collection) were collected from ovaries of slaughtered cows and cultured in vitro with one of the four treatments: follicle stimulating hormone (FSH; 100 ng/ml) alone; FSH plus epidermal growth factor (EGF; 100 ng/ml); FSH plus insulin-transferrin-selenium (ITS; +1%) or FSH plus hypoxanthine (4 mM) in tissue culture medium (TCM 199) suppleme...
متن کاملMorphological Study of Isolated Ovarian Preantral Follicles Using Fibrin Gel Plus Platelet Lysate after Subcutaneous Transplantation
OBJECTIVE Ovarian and follicle transplantation may preserve fertility in young cancer survivors. In this study, we have transplanted preantral follicles using fibrin gel as a carrier and fibrin gel supplemented with platelet lysate (PL) as a rich source of angiogenic and growth factors. The purpose of this study was to evaluate the role of fibrin gel and PL in follicle transplantation. MATERI...
