Research Abstract |
In this study, we could activate dormant primordial follicles following the in vitro treatment of ovarian fragments to stimulate PI3K/PKB signaling system. The transplantation of these cultured ovarian fragments allowed to grow the activated primordial follicles to preovulatory stage. We could retrieve mature oocytes from the preovulatory follicles and normal pups were delivered after in vitro fertilization and embryo transfer. This method is expected to develop a novel method for pregnancy by using autologous ooytes in patients who lack follicle development but have residual primordial follicles.
