Current achievements and future research directions in ovarian tissue culture, in vitro follicle development and transplantation: implications for fertility preservation. Vrije Universiteit Brussel
Methods: Specialist ...
In vitro oocyte growth is widely studied as an alternative fertility preservation approach. Several animal models are used to generate extensive information on this complex process regulated by the constant and dynamic interaction between the oocyte and its somatic compartment throughout follicle growth and maturation. A 2-dimensional (2D) attachment mouse secondary follicle culture system was used to assess the oocyte's capacity to overcome ...
STUDY HYPOTHESIS: Does in vitro follicle culture (IFC) have an effect on maintenance of imprinted DNA methylation in preimplantation mouse embryos?
STUDY FINDING: We report similar alterations in the methylation pattern of H19 imprinted maternally expressed transcript (H19), small nuclear ribonucleoprotein polypeptide N (Snrpn) and mesoderm specific transcript (Mest) imprinted genes in mouse blastocysts obtained after ovulation ...
The currently available assisted reproduction techniques for fertility preservation (i.e. in vitro maturation (IVM) and in vitro fertilization) are insufficient as stand-alone procedures as only few reproductive cells can be conserved with these techniques. Oocytes in primordial follicles are well suited to survive the cryopreservation procedure and of use as valuable starting material for fertilization, on the condition that these could be ...
